                                               CAUTION

Your Universal Diesel engine is supplied with top quality, factory tested components. These will not,
however, replace safe practices in the handling of fuel and the use of your engine. The following pro-
cedures, if observed, will help insure safe operation and prevent damage to your engine and its
components.


SAFETY PROCEDURES:

     KEEP THE ENGINE AND ENGINE COMPARTMENT CLEAN AND FREE FROM OILY WASTE
     AND CLOTHS.

     KEEP FUEL AND OIL OUT OF BILGE.

     PERIODICALLY INSPECT THE ENGINE, EXHAUST SYSTEM, FUEL LINES AND WATER CON-
     NECTIONS FOR LEAKS.

     DO NOT OVERFILL THE FUEL SUPPLY TANK, THIS MAY CAUSE RAW FUEL TO AC-
     CUMULATE IN THE BILGE.

     THE BLOWER SHOULD ALWAYS BE OPERATED FOR APPROXIMATELY FOUR (4) MINUTES
     PRIOR TO STARTING THE ENGINE SO THAT THE ENGINE COMPARTMENT WILL BE COM-
     PLETELY VENTILATED, IF BLOWER IS INSTALLED.


LUBRICATION:

     THE ENGINE IS SHIPPED FROM THE FACTORY WITH THE CRANKCASE EMPTY.
     THE CORRECT GRADE AND AMOUNT OF OIL MUST BE ADDED BEFORE OPERATION, SEE
     SPECIFICATIONS AND FILL TO FULL MARK ON DIPSTICK.

     THE TRANSMISSION IS FILLED BEFORE SHIPMENT BUT THE OIL LEVEL MUST BE CHECK-
     ED BEFORE OPERATION, SEE SPECIFICATIONS, PAGE 41.


ALTERNATOR:

     TO PREVENT ALTERNATOR DAMAGE, DO NOT OPEN OR SWITCH BATTERY CIRCUITS
     WHILE THE ENGINE IS RUNNING.


RACING THE ENGINE:

     DO NOT RACE THE ENGINE. THIS PRACTICE MAY CAUSE SERIOUS DAMAGE.


DECOMPRESSION LEVER:

     DO NOT USE THE DECOMPRESSION LEVER TO STOP THE ENGINE, THIS WILL CAUSE
     SERIOUS DAMAGE TO THE EXHAUST VALVES. MODELS M-12, M2-10, M3-20, M4-30 ANd M-3S
     DO NOT HAVE A DECOMPRESSION LEVER.

MAINTENANCE AND UPKEEP:

     IT IS THE OWNER'S OR OPERATOR'S RESPONSIBILITY TO PERFORM ALL NECESSARY
     PREVENTIVE MAINTENANCE AND UPKEEp, AT LEAST SEMI ANNUALLY.



                                                    4
                                   -CAUTION-

FRESH WATER COOLING SYSTEM: ALL MODELS EXCEPT M-15.

   THIS SYSTEM MUST BE FILLED SLOWLY WITH A SOISO BLEND OF WATER AND A GOOD
   GRADE OF PREMIUM ANTIFREEZE. (THE COOLANT BLEND MAY CHANGE, BASED ON
   CLIMATIC CONDITION IN YOUR AREA.) OR YOU MAY ALSO USE CLEAN FRESH WATER WITH
   AN ANTI RUST INHIBITOR. DO NOT USE PURE ANTIFREEZE. AFTER ENGINE HAS REACHED
   OPERATING TEMPERATURE IT MAY REQUIRE ADDING MORE COOLANT AS THE AIR IS
   PURGED FROM THE SYSTEM. IF ENGINE OVERHEATS, RECHECK LEVEL, IF HOT WATER
   HEATER IS INSTALLED, ALL AIR MUST BE REMOVED FROM THE LINES AND SYSTEM TO
   PREVENT OVERHEATING USUALLY BY MEANS OF AN ADDED BLEED VALVE IN HEATER LINE
   OR EXPANSION TANK IN THE SYSTEM.


COOLING SYSTEM: Model 15

   THE M-15 WHICH IS COOLED DIRECTLY BY SEA WATER, USES A RECIRCULATING SYSTEM
   WHICH DISCHARGES THE WATER AND VAPOR OVERBOARD WITH THE EXHAUST GASES.


EXHAUST SYSTEM:

   IT SHOULD BE INSTALLED WITHOUT SHARP BENDS AND SHOULD BE DESIGNED TO DRAIN
   ANY WATER AWAY FROM THE ENGINE. THE WATER INLET TO EXHAUST LINE MUST BE
   LOCATED TO PREVENT WATER FROM BACKING UP INTO THE ENGINE.lF A WATER-LIFT
   "CAN" TYPE MUFFLER IS USED, BE SURE IT IS LARGE ENOUGH TO HOLD APPROXIMATE-
   LY 3 TIMES THE AMOUNT OF WATER THAT MAY BE IN THE LINES WHEN THE ENGINE IS
   SHUT DOWN SO THAT WATER WON'T BACK UP INTO THE ENGINE.

   CAUTION
   PROLONGED CRANKING OF THE ENGINE WITH FAILURE TO START CAN FILL THE EX-
   HAUST SYSTEM WITH SEA WATER CAUSING IT TO BACK UP INTO THE ENGINE CAUSING
   SERIOUS DAMAGE TO THE ENGINE WHEN CRANKING IS STOPPED.
   CHECK COMPLETE SYSTEM AT LEAST MONTHLY FOR LEAKS.


STARTING & STOPPING ENGINE:

   BE SURE TO CAREFULLY READ INSTRUCTIONS ON HOW TO START AND STOP YOUR
   ENGINE BEFORE STARTING ENGINE.


FUEL SUPPLY:

   DO NOT RUN ENGINE OUT OF FUEL OR RE-BLEEDIN.G OF YOUR FUEL SYSTEM WILL BE
   REQUIRED.

   FUEL MUST BE FREE OF ANY MOISTURE OR IMPURITIES. CHECK CAREFULLY. MOISTURE
   CAN SERIOUSLY DAMAGE PUMP AND NOZZLES. AN ADDITIVE SHOULD BE USED AS
   BACTERIA GROWTH CAN PREVENT GOOD RUNNING CONDITIONS CAUSING THE ENGINE
   TO RUN ERRATIC OR LOSE POWER.


STARTING MOTOR:

   CRANK THE ENGINE FOR ONLY 10 SECONDS AND PAUSE FOR 10 SECONDS. REPEAT UNTIL
   ENGINE STARTS. NEVER CRANK ENGINE LONGER THAN 20 SECONDS WITHOUT A PAUSE
   TO PERMIT STARTER TO COOL DOWN. USE OF GLOW PLUGS WILL AID IN STARTING,
   REDUCE CRANKING TIME AND INCREASE BATTERY LIFE. ENGINE SOLD AFTER EARLY 1983
   REQUIRES GLOW PLUG BUTTON TO BE ENGAGED IN ORDER FOR STARTER BUTTON TO
   ENERGIZE STARTER.

                                      GENERAL INFORMATION


ENGINE:

   Universal Diesel engines are four stroke engines. They are designed with special swirl combustion
   chambers, balanced crankshaft system for minimum vibration and noise levels.


COOLING SYSTEM: All Models Except M-15

   Engines are fresh water cooled, employing a rubber impeller sea water pump moving sea water
   through a heat exchanger thereby lowering the temperature of the fresh water coolant. A fresh
   water coolant supply is maintained in the expansion tank which is an integral part of the exhaust
   manifold. Coolant level should be checked at regular intervals and at least once each season for
   leakage, deposits and general condition. Always close the sea water cock before attempting any
   work on the coolant system. (Note the make of sea water pump for service parts under general
   information. )


COOLING SYSTEM: Model M-15

   Engine is sea water cooled, having a rubber impeller sea water pump, with a recirculating
   temperature control thermostat. The mixing tee is to be located below the engine and sea water
   level to prevent air from entering the system causing overheating.


LUBRICATION SYSTEM:

   Engines are pressure lubricated and use replaceable oil filters which should be changed regularly.


FUEL SYSTEM:

   Tt'le fuel system utilizes either an electric on all current models or mechanical fuel pump on early
   M-15 & M-40, fuel filter, fuel injection pump with injectors and necessary fuel lines. Unused fuel
   coming from the injector nozzles is returned to the top of the fuel supply tank through a fuel return
   line.


ELECTRICAL SYSTEM:

   All models are equipped with a 12 volt starter and a 51 amp alternator. Battery cable connections
   as well as all other electrical connections should be checked regularly. The V-belt driving the alter-
   nator and water pump should have finger pressure deflection of approximately 1/2".

   1.     Battery ground cable (-) should be connected to a component or cylinder block which is
          constructed of cast iron or steel.

   2.     Do not connect to the transmission, bell housing or front timing cover case.

   3.      It is recommended all ground connections are secure and properly coated to prevent corro-
          sion or improper grounding. Check connection semi-annually.




                                                   6
GENERAL CARE:

     If the boat is left afloat for periods of a month or more, the engine should be started at least every
     14 days to prevent internal corrosion.

     Regularly spray external unpainted surfaces and exposed, unpainted electrical equipment with a
     corrosion and moisture protective coating.


ENGINE ALIGNMENT TO SHAFT COUPLING:

     It is the responsibility of the dealer or yard to properly align the engine and shaft to within .002" to
     .004" inches. The boat must be in the water when this is done. Alignment is not the responsibility
     of Universal Motors. If not done properly damage to shaft and engine can occur, usually vibration
     is present if alignment is off.

WARRANTY WORK APPROVAL OR PROOF OF PURCHASE DATE.      --


                    PREPARATIONS FOR STARTING YOUR NEW DIESEL ENGINE

For long dependable service, become familiar with the operating requirements of your engine.

All Universal Diesel engines are completely factory tested under load conditions before shipment.

In preparation for starting engine, oil must be added to the crankcase. Refer to specifications for
lubrication, oil type and capacity. Recheck oil level on dipstick, it should be to full mark, do not overfill,
when checking oil remove dipstick, wait 15 seconds, then recheck.

The oil level should be checked before the first start-up each day. Dipstick has high and low markings.
Oil levels either above or below these marks should never be allowed. Oil is put into the engine by
removing the screw cap on the top of the rocker arm cover. Fill the crankcase with oil to the upper
mark on the dipstick and securely replace the filler cap.

THE TRANSMISSION IS SHIPPED WITH OIL, BUT SHOULD BE CHECKED PRIOR TO OPERATION.
Refer to specification of oil type and capacity. Recheck oil level on dipstick. (DIPSTICK TO BE IN-
SERTED ONLY. DO NOT SCREW IN). See transmission instructions for additional information. FILL
TO INDENTED RING ON DIPSTICK only.

An unrestricted water supply must be provided to the engine. Use a minimum of 1/2" through hull fit-
ting. Locate the scoop where it will have a full supply of water at all times regardless of running posi-
tion or rough seas. A sea cock or gate valve is necessary at the water inlet point. The water pump has
a 3/8" N.P.T. suction inlet and the heat exchanger has a 3/8" N.P.T. water outlet. Use a non-
collapsible hose for the suction side. A water strainer installed in the line ahead of the water pump aids
in preventing clogging of the cooling system. The exhaust pipe is 1-1/4" N.P.T.' on all models except
M-50, which is 1-112" N.P.T.

The fresh water manifold on all models except M-15 should be filled slowly to the bottom of the filler
cap. A 50/50 mixture of fresh water and antifreeze solution is acceptable as an all weather coolant,
eliminating the need to drain the fresh water system for cold weather operation or storage. A coolant
mixture may change based on climatic conditions in your area. The rust preventive will aid in reducing
rust formation if no antifreeze is used.

Model 15, being sea water cooled, draws its water directly from the sea, filling the engine system and
discharging the hot water overboard into the exhaust line.

Be sure water pump is lubricated by turning grease cup (if provided on your engine) clockwise 112 turn
at 30 hour intervals. Pumps with no grease cup do not require lubrications.




                                                       7
Transmission shifting controls must allow the clutch to engage in the full forward and reverse positions.
Restricted or partial engagement will cause undue wear. The transmission should always be in the
neutral position before starting the engine. Also, the transmission shifter arm must be at a 900 angle to
the transmission bracket cable when in neutral.

DO NOT LEAVE GEAR IN FORWARD DURING SAILING WITH ENGINE OFF.

On all models, the fuel line must be connected from the fuel tank to the electric fuel pump, then to the
fuel filter. On Model 15, connect directly to the fuel supply line. A fuel return line must be connected
from the injector nozzles to the top of the fuel tank so that the unused fuel can blow back into the fuel
tank. IT IS VERY IMPORTANT TO KEEP ALL FUEL LINES FREE OF DUST AND IMPURITIES.
THEREFORE, BLOW OUT LINES BEFORE CONNECTING.

Check fuel supply and make sure fuel lines are tight. Any fuel leakage must be corrected before any
attempt to start the engine. If fuel line leaks are discovered or any work is done on the fuel system, it
may be necessary to bleed the fuel system before the engine will start. (Refer to bleeding instructions
in this manual if that procedure becomes necessary.)

Check all electrical connections. A wiring diagram is included in this manual. GROUND IS NEGATIVE
and the ground terminal should be connected to the engine block. Make sure it is metal to metal con-
tact, and securely tightened. Also, check the battery to be sure all cells are covered with electrolyte. Do
not allow flames or sparks near battery openings. Gases produced during normal battery charging are
EXPLOSIVE.




                                     BEFORE STARTING THE ENGINE


  1. HAVE SAFETY EQUIPMENT ON BOARD AND KNOW HOW TO USE IT.

  2. VENTILATE ENGINE COMPARTMENT BY OPENING HATCHES, OR BLOWER IF INSTALLED.

  3.   CHECK CRANKCASE OIL LEVEL ON DIPSTICK, SHOULD BE AT FULL MARK.

  4.   CHECK TRANSMISSION OIL LEVEL. (Refer to transmission servicing.)

  5.   CHECK FRESH WATER LEVEL IN MANIFOLD OR EXPANSION TANK IF INSTALLED, ON ALL
       MODELS EXCEPT M-15.

  6.   CHECK FUEL SUPPLY.

  7    FUEL SHUT-OFF VALVE SHOULD BE OPEN.

  8. SEA WATER VALVE TO WATER PUMP MUST BE OPEN.

  9.   EXHAUST SHUT-OFF VALVE MUST BE OPEN OR END-PLUG REMOVED IF INSTALLED.

 10. REMOVE ANY OBSTRUCTION CAUGHT IN AIR INTAKE SCREEN.

 11. TURN MAIN BATTERY SWITCH "ON".

 12. TURN IGNITION KEY TO "ON" POSITION, TO ENERGIZE ELECTRIC FUEL PUMP ON ALL
     MODELS TO BLEED THE FUEL LINES AND FILTER. (THIS IS USUALLY COMPLETED BY THE
     BOATBUILDER AT THE TIME THE ENGINE IS TESTED AND SHOULD NOT BE REQUIRED BY
     CUSTOMER.)

 9.   Activate "Glow Plug" switch for 30 seconds to 1 minute, depending on the outside air
      temperature. It may be necessary to hold the glow plugs on during the time the engine is cranked
      in very cold outside temperatures.

10. Turn key to full "right" position to crank engine. Release key immediately after start. MAKE SURE
    THE KEY RETURNS TO THE "ON" POSITION.

      NOTE: When cranking engine, only crank engine for 10 seconds and pause for 10 seconds.
      Repeat until engine starts. (See Caution printed on Starter Motor.)

11.   Check oil pressure light. (Should go out after engine starts.)

12. Ammeter should indicate "Charge", depending on battery condition.

12A. If you have a voltmeter in place of an ammeter, it should read 12.5 to 14.5 volts, indicating alter-
     nator is working.

13.   Check cooling system. (Make sure water pump is operating by checking for water coming out of
      exhaust pipe with exhaust gases.) Temperature on gauge should gradually increase to 165°F to
      195°F on all models except M-15. Temperature on Model 15, should read between 135°F and
      155°F.

14.   If oil pressure light does not go out or no water overboard or temperature is not normal, STOP
      ENGINE AT ONCE! Recheck all items listed to correct problem.                              --

15.   If all indications are normal after start-up, continue to run engine for about 10 minutes to be sure
      all systems remain normal and operating temperature is maintained.

16. With boat still SECURED to mooring and throttle reduced to idle, check transmission operation by
    shifting from neutral to forward, to neutral, to reverse to neutral. Make sure no lines or obstruc-
    tions are near the propeller.

17.   Stop engine after above check out has been accomplished and recheck oil and water levels.

                                                 CAUTION

          COOLING SYSTEM IS UNDER PRESSURE AFTER OPERATION. REMOVE CAP
          SLOWLY. COOLANT WILL BE VERY HOT, USE A RAG. YOU COULD GET
          BURNED.

                             ENGINE BREAK-IN AND GENERAL RUNNING

1.   Engine break-in period should be approximately 10 hours of operation at 75% of normal cruising
     speed.

2.   On your trial cruise, check the propeller shaft for abnormal vibration and engine mounts for
     tightness. Realignment of the propeller shaft may be required if noticeable vibration is present.
     Boat should be in the water when checking alignment. Universal is not responsible for shaft align-
     ment, or locking nuts on mounts coming loose.

3.   After the break-in period, an average cruising speed for a sail boat installation is about 80% of the
     maximum engine speed obtainable, to achieve hull speed.

4. Periodically check oil light indicators, ammeter, temperature and exhaust water for normal opera-
   tion, this is the operators responsibility.

5.   When shifting transmission, engine R.P.M. should be reduced to idle, then shift transmission firm-
     ly from one direction to another. A slight pause in neutral will allow propeller to slow and add life
     to transmission. In adverse conditions due to winds, sea, or higher RPM's it may be more difficult
     to shift.


                                           STOPPING THE ENGINE

1. Place throttle in the idle position.

2.   Place transmission shift lever in neutral. (Center position).

3. Leave engine idle for approximately 1 to 2 minutes for it to cool down.

4. To stop engine on early Models 15, 18,20,30 & 40, hold throttle lever in the back position
     against the spring loading until the engine stops. Then release the throttle from the stop position
     and throttle will return to the idle position. Repeat if engine does not stop the first time. Models
     M-12, M-25, M2-12, M3-20, M4-30, M-25XP, M-35, M-40, M-SO have a separate stop lever for shut-
     ting the engine down. All newer models have a shut down lever on panel, pull
     lever to stop engines, then tum off key. The newer models have a separate shut down lever.


5.   Tum key to the "OFF" position to shut off the electric fuel pump and accessories. If not in
     "OFF" position, it may drain the batteries.

6. Open battery master switch ONLY AFTER ENGINE HAS COME TO A COMPLETE STOP!
   This will prevent alternator and regulator damage.

7.   00 NOT USE THE DECOMPRESSION LEVER TO STOP THE ENGINE! This practice could
     seriously damage the exhaust valves.

8.   You may want to close the fuel and sea water valves after stopping the engine. If so, BE SURE
     TO RE-OPEN THEM BEFORE RESTARTING. FAILURE TO 00 SO COULD CAUSE ENGINE
     TO OVERHEAT AND DAMAGE TO THE PUMP IMPELLER, OR FUEL LINES TO BECOME AIR
     LOCKED. THIS SITUATION WOULD THEN REQUIRE BLEEDING OF THE FUEL SYSTEM
     BEFORE RESTARTING ANDIOR REPLACING THE PUMP IMPELLER.

                                          DECOMPRESSION LEVER

A decompression lever fitted to the engine enables the user to start the engine easier when it is ex-
tremely cold, when the battery is low or when bleeding the fuel system. There is no decompression
lever on Models 12, M2-12, M3-20, M4-30 and M-35.


                                                  -CAUTION-

           THE DECOMPRESSION LEVER MUST NOT BE USED TO STOP THE ENGINE
           EXCEPT IN EMERGENCY SITUATIONS SUCH AS RUN AWAY ENGINE OR
           THROTILE DAMAGE, AS SERIOUS DAMAGE CAN BE DONE TO THE EX-
           HAUST VALVES.

When the battery is weak or starting in extremely cold weather:
 (In most cases decompression is not necessary.)

     Models with Glow and Start Buttons and Decompression:

      1.   Pull decompression lever to release position.

      2.   Turn ignition switch to ON position.

      3.   Hold Glow Plug Button in for 30 to 60 seconds then press Start Button to crank engine
           (Models after early 1983).

      4.   After 3 to 5 seconds, when the engine has gained momentum, return decompression lever to
           its original position. Engine should now start.


     Models With Start On Key Switch:

      1.   Pull decompression lever to release position.

      2.   Turn key to ON position.

      3.   Energize glow plugs for 30 to 60 seconds.

      4.   Turn key to start position to crank engine.

      5.   After 3 to 5 seconds, when the engine has gained momentum, return decompression lever to
           its original position. Engine should now start.


                                                  INSTRUMENT PANEL

Refer to the instrument panel drawing when becoming familiar with the start up procedure or any
general operating requirements of the engine.

The "Blower" switch (if equipped with engine) will remain in the "ON" position until it is turned off.

The "Glow Plug" or pre-heat switch requires continuous pressure for whatever time it is necessary to
activate the glow plug.

The "Oil Pressure" light will come on when starting the engine but should go out after the engine
starts. A low oil level in the engine crankcase or a serious oil leakage should be suspected if the light
comes on at any other time during engine operation.
Old style key switch is a four position selector type. Far left, "ACCESSORY"-"OFF"-"ON"-
"START" at the far right moving clockwise. The key will spring return to the "ON" position when
released after start up.

New style key switch is ON-OFF only; glow and start switches are push button type. Both must be
engaged to start engine.


                                                      11
Operating temperature is approximately 165°F to 195°F on all models except M-15. Operating
temperature is approximately 135°F to 155°F on Model 15. The ammeter should indicate the charge re-
quired based on equipment and battery condition.

There are three (3) New style "Universal" panels.

      1. Standard: Includes temp. and AMP gauges, oil light, on-off key switch, glow plug and start
         300680 buttons.

      2.   Deluxe:   Same as Standard plus a tachometer with 4 selection stations on the back. To be
           300685    set to correct Model for accurate readings.

      3.   Custom:   Same as Standard plus a tachometer/hour meter with Model selection station on
           300690    back and a low-oil high-temp audio alarm with red light.

                     PREPARING THE ENGINE FOR WINTER STORAGE OR LAYUPS

Proper preparation of your engine for storage will avoid damage and minimize expense when agai,n
placing your engine in service.

NOTE: It is recommended that your engine be winterized by an authorized Universal mechanic or at
least, a trained mechanic familiar with the engine and its options.


LUBRICATION SYSTEM:

      1.   Before boat is lifted out of the water, run the engine until operating temperature is attained.

      2.   Stop engine after warm up and remove crankcase oil through the dipstick hole using hand
           sump pump designed for that purpose. Replace dipstick after oil has been removed or
           through oil drain hose if one is provided. The newer engines have a drain hose for changing
           crankcase oil.

      3.   Refill crankcase with new oil and replace filler cap.

      4.   Run engine again for about 5 minutes to distribute a protective film of clean oil to act as a
           rust preventive during storage.

TRANSMISSION: (See transmission instructions)

      1.   Fill transmission completely with type AFT or DEXRON II transmission oil. You may just add
           to the existing oil or drain the old oil and completely refill with new transmission oil.

      2.   Be sure both drain and filler plugs are tight after draining or adding to the oil in the
           transmission.

      3.   Transmission is now ready for storage.


SEA WATER COOLING SYSTEM: All Models Except M-15

     OPTION #1 (Dry Storage)

      1. To drain sea water system, disconnect hose end at sea water pump that comes from heat
         exchanger.

           Lower free end of hose to a pOint approximately level with the front engine mount. This will
           allow the sea water to drain from heat exchanger and hoses.

      2.   Loosen the 4 or 6 screws on the sea water pump cover plate. Tap the plate lightly to loosen
           it, this will allow pump to drain.

      3.   After pump has drained, apply a light coat of lubrication to protect pump and impeller during
           storage and replace cover.

      4.   Dr~in   exhaust muffler and system separately.

OPTION #2 (Wet Storage)

           Repeat Steps 1, 2 and 4 of Option #1

      1.   Disconnect sea water inlet hose at sea cock shut off valve. BE SURE SEA INLET VALVE IS
           CLOSED FIRST.

      2.   After the inlet hose has stopped draining, place hose into a (2 Gallon) container of an-
           tifreeze. Start engine and run the two gallons on antifreeze through the system until the an-
           tifreeze comes out the exhaust outlet, stop engine and check item 4. Make sure you do not
           run out of antifreeze while engine is running.


                                                     14
     3.   You should now have antifreeze in sea water pump, hoses, heat exchanger and exhaust
          system.

     4.   If aqua-lift or pot type muffler is used, it is recommended to drain prior to pumping anti-
          freeze thru system and afterwards to prevent coolant from backing up into the engine.


SEA WATER COOLING SYSTEM: Model M-15

    OPTION #1

     1. Open the cylinder block drain cock on the side of the block where hose from water pump
        enters, and drain.

     2.   Loosen water pump cover plate, allowing pump to drain, lubricate and replace cover.

     3.   Remove drain plug or rear bottom of exhaust manifold, and drain.

     4.   When boat is out of water, inlet lines to pump and thermostat will drain. Close sea cock
          valve when completed for storage.

     5.   If aqua-lift or can type muffler is used, it is recommended to drain muffler and lines of water.

    OPTION #2 (With engine at operating temperature and stopped)

     1.   Shut off sea cock valve.

     2.   Remove hose at sea cock. Let water drain from hose. Place inlet hose into container of an-
          tifreeze (with decompression lever on). Crank engine over at 10 second intervals until an-
          tifreeze comes out exhaust outlet.

     3.   If aqua-lift or can type muffler is used, drain prior to pumping antifreeze thru system and
          afterwards to prevent coolant from backing up into the engine.

     4.   You may wish to do option -1 prior to -2 to insure all water is out of engine and exhaust
          system.

     5.   Replace hose to sea cock when complete. Be sure sea valve is closed.

     6.   Antifreeze will aid in coating inside of the engine, reducing rusting.


TO DRAIN FRESH WATER COOLING SYSTEM: All Models Except M-15

     1.   Remove pressure cap from manifold. (when engine is cool)

     2.   Open drain cock located above oil filter to drain engine block and head cylinder.

     3.   Open the in-line drain petcock located below the alternator. This will drain the manifold, heat
          exchanger and engine fresh water pump.

     4.   Remove 1/8" pipe plug at lower rear of manifold, to drain manifold separately.

     5.   Close all drain valves and petcocks when draining has been completed.

     6.   If antifreeze solution is used, it is not necessary to drain the system each year, providing you
          have the correct mixture to prevent freezing during winter storage.




                                                    15
EXHAUST SYSTEM:

    1.   Exhaust pipes and muffler should be drained of sea water. Allow the exhaust pipes to dry
         out. Seal exhaust pipe end to prevent entrance of moisture into the engine through exhaust
         valves that are open.

    2.   See Option -2 under Sea Water Cooling System appropriate for your model.

    3.   All can type mufflers should be drained after any long periods of cranking, as Sea Water
         pump will fill the muffler causing water to backup and enter the engine.


ELECTRICAL SYSTEM:

    1.   Remove battery and store it in a warm dry area.

    2.   Protect other electrical parts against moisture.


FUEL TANK:

    1. To protect against corrosion or moisture in the fuel supply tank, either fill the tank with fuel
       or drain completely and seal top securely for storage.

    2.   A diesel additive is recommended to prevent bacterial growth in the fuel.


GENERAL:

   You may want to completely cover the engine to provide additional protection. Care should be
   taken when covering so that electrical connections are not loosened and that fuel lines are not
   bent or broken.

                                PREPARING ENGINE FOR SPRING SERVICE

Preparation of the engine should include all those items of maintenance necessary to permit satisfac-
tory operation of the engine. A properly serviced engine will give a full season of carefree pleasure.
The amount of service needed will be determined by the storage procedure of the previous fall. Refer
to the section of the manual covering initial start up of the engine.


LUBRICATION SYSTEM:

      1. Drain oil from crankcase using hand sump pump through the dipstick hole or oil drain hose if
         installed.

      2.   Install new oil filter.

      3.   Refill crankcase with recommended grade and amount of engine oil. (Fill to upper or full
           mark on dipstick). Do not overfill.

      4.   Be sure filler cap is secure after filling crankcase and that no oil leaks are apparent.


TRANSMISSION:

      1. If transmission was completely filled for winter storage, some oil will have to be removed to
         attain the correct level in the transmission.

      2.   Check transmission oil level according to specifications found in this manual.

      3.   Be sure all plugs are secure and that no leaks are apparent. The drain plug should be
           checked regularly.

           CAUTION: DO NOT CROSS THREAD THE DIPSTICK THREADS AS IT MAY REQUIRE
           HOUSING REPLACEMENT.


SEA WATER COOLING SYSTEM:

      1. Remove front cover of pump if system was drained for storage. Inspect rubber impeller, light-
         ly lubricate pump impeller, replace gasket and cover securely when inspection and lubrica-
         tion have been completed.

      2.   If impeller is not serviceable, see instructions covering the replacement of the sea water
           pump impeller in the maintenance section of this manual.


COOLING SYSTEM: Model M-15

On Model 15, make sure all plugs and hoses are replaced and secure. Remove inlet hose on pump
and add about 314 oz. of lube oil. This will lubricate impeller when engine first starts until it picks up
sea water.


FRESH WATER COOLING SYSTEM: All Models Except M-15

      1.   Inspect the heat exchanger and exhaust manifold for secure mounting and interior
           cleanliness. If system was filed with a 50/50 water and antifreeze mixture for storage, leaks
           will be easier to detect than if the system was drained. The coolant should be relatively clear
           and should be free of scale or other foreign particles.

      2.   If system was drained and inspection is satisfactory, fill slowly with coolant and replace
           pressure cap. Recheck coolant level after engine has run and reached operating
           temperature. Use caution when removing cap when engine is hot, you could get burnt.

      3.   Use antifreeze or rust preventative in system to prevent rust.

                                                     17
EXHAUST SYSTEM:

    1.   Check all hoses and hose clamps for serviceability and security. Any worn or damaged
         hoses or clamps must be replaced before operation.

    2.   Check all valves and remove all plugs before operation.

    3.   Check complete system monthly for leaks, make repairs as needed.


ELECTRICAL SYSTEM:

    1.   Inspect all wiring, terminals, controls and switches for damage or corrosion.

    2.   Install a fully charged battery and connect it correctly. (NEGATIVE GROUND.) Be careful to
         not short across negative and positive terminals.


FUEL SYSTEM:

    1. Fuel tank must be clean, free of water and securely mounted. If it was filled with fuel for
       storage, FUEL MUST BE CLEAN.

    2.   Check fuel cap vent hose. It must be open for unrestricted air venting.

    3.   Fuel lines must be secure and all clamps and nuts tight. Lines must not be leaking. Fuel
         system will require bleeding before operation, if tank has been drained or filter has been
         replaced. (See instructions covering fuel system bleeding).


GENERAL:

   All of the above items must be carefully checked if satisfactory operation is to be expected, good
   common sense will aid during servicing.

   Refer to the start up check list in this manual after above items have been checked and before at-
   tempting to start the engine so that the proper procedure may be followed. In some cases other
   add ons may require serviCing.

   WITH THE BOAT IN THE WATER, check freedom of the propeller shaft in the bearings and
   alignment of the propeller shaft with the engine. Shaft alignment should not be more than .002" to
   .004" out at four pOints in one position at coupling flange and the same four pOints in the same
   position when shaft and coupling is rotated 1800 from first check. If propeller shaft is out of align-
   ment, we strongly recommend that re-alignment be performed by a qualified mechanic familiar
   with the installation.

   Also, it may be necessary to tighten the stuffing gland just enough to stop excessive leakage
   along the shaft. Excessive tightening will cause power loss and burned stuffing material. A slight
   seepage is necessary to lubricate the stuffing gland.

   Any problems arising from this pre-use inspection requiring special tools or attention should be
   referred to the boat dealer, a Universal Dealer service center, or a qualified diesel engine service
   center.

                                      MAINTENANCE OF YOUR ENGINE

Unless major repair work is done on the engine, timing should not be required.


FUEL INJECTION TIMING:

     Basic tools required: (A) - 10 MM   Socket wrench
                           (B) - 13 MM   Socket wrench
                           (C) - 17 MM   Open end wrench
                           (D) - 12 MM   Box end wrench
                           (E) - 27 MM   Socket (1-1/16")

     Engine firing order - Two cylinder - 1 - 2
     (Front V belt end)
                           Three cylinder - 1 - 2 - 3

                             Four cylinder -   1-3-4-2

      1. Remove fuel lines from injector pump fittings on injector pump (Tool C).

      2.   Pull decompression lever so that it will remain in the decompression position. No decompres-
           sion lever on Model-12.

      3.   Open throttle fully.

      4.   Energize electric fuel pump and turn engine over with starter to ensure that fuel is coming
           out of each injector pump opening. Have clean rags around opening to soak up fuel.

      5.   Wipe off any fuel on injector pump body and the top of each injector opening.

      6.   Turn crankshaft over by hand, being careful not to damage spline on end of crankshaft.
           Engine rotation will be clockwise. STOP IMMEDIATELY at the first sign of fuel movement in
           the injector pump fuel fitting, for whichever injector pump is being checked. (No. 1 injector
           pump is the closest to the V-belt end of the engine).

      7.   Remove cover from flywheel timing mark inspection hold located inside of left engine mount
           (Tool B).

      8.   Check alignment of mark on flywheel with the timing pointer on the wall of the inspection
           hole. The 1-FI mark on the flywheel represents fuel injection of No.1 cylinder.2-FI
           represents No.2 cylinder, etc.

      9. If timing pointer and the flywheel marking 1-FI is aligned then No.1 cylinder is properly tim-
         ed for fuel injection and should require no adjustment. The same will be true for No.2, No. 3
         and No. 4 cylinders if the above steps are followed.
     10. In order to determine if timing is off, or if the injection pump is faulty, it is necessary to
         recheck the timing for each cylinder two or three times.

     11     If there are variations in repeatability in the alignment of pOinter and timing mark, a faulty
           fuel injector pump may be suspected.

     12.   If timing marks repeat to same location but are off 3/16" or more above or below the pointer,
           this indicates that the engine must be retimed.

If alignment of the timing mark is not within 3/16" above or below the pointer, the above steps must be
taken to time the engine. If the timing is found to be satisfactory, then reconnect all fuel lines and fit-
tings and tighten. The fuel system must be bled beforeh)the engine will operate properly. (See fuel
bleeding instructions on page 28).

Turn crankshaft over by hand (Clockwise) being careful not to damage the spline on the end of the
shaft. Turn until pointer aligns with timing mark 1TC on flywheel (Figure 4A). Check to make sure both
intake and exhaust valves on No.1 cylinder are loose. If not, turn crankshaft one more complete revolu-
tion to bring No. 1 cylinder onto compression. Valves can now be set on No. 1 cylinder.. This procedure
is true for No. 1 cylinder on all models. To set the valves on the remaining cylinders, follow the mat-
ching diagrams above being sure that both intake and exhaust valves are loose at the corresponding
cylinder before adjusting.

CAUTION: DO NOT use the timing marks 1-FI, 2-FI, etc. These marks are used for timing fuel injector
pumps only.

                                          ADJUSTING FUEL TIMING

Steps necessary for fuel timing:

 1.   Remove air intake manifold so that the fuel injector pump can be removed without interference.

 2.   Set throttle lever at full speed.

 3.   Remove injector pump side cover. This will enable you to visually check to insure that the fuel rack
      pin jnside the pump properly aligns with the opening in the top of pump housing when being
      removed to prevent binding or shearing of the pin. This pin is critical to proper pump operation
      and if damaged will require replacement of the complete pump.




                                                     20
 4.   The injector pump internal unit can now be loosened and removed. It may be necessary to remove
      fuel lines from injector nozzles to aid in pump removal

 5.   There are several shims located just below the pump top plate which will be used to adjust the
      timing. These shims are .006 inch thick and are equal to 1-V2 ° or approximately 3/16" of distance
      on the circumference of the flywheel. Addition of shims will retard the timing and removing shims
      will advance the timing.

 6.   If the mark on the flywheel is below the pointer, the fuel is being injected sooner than required and
      the fuel timing must be retarded. Shims must be added until the timing marks are aligned. The op-
      posite is true if the flywheel mark is above the pointer. See figure 5.

7.    If at all possible, it is better to operate the engine with the timing advance rather than retarded.

8.    Replace fuel injector pump, making sure the fuel rack pin aligns with the housing opening and is
      properly inserted into the slotted arm. Tighten injector pump cover in place. Reconnect fuel line
      from fuel filter to pump. Repeat steps 2 thru 12 on engine timing.

 9.   If timing is satisfactory, then reassemble. Be certain that all plates, covers, fuel lines and connec-
      tions are tight and free of leaks so that safe operation may be expected when the engine is
      started. Clean engine throughly.

10.   Caution: Be sure all fuel lines and connections are kept clean during adjusting, to prevent fouling
      of nozzles when reassembled.

DECOMPRESSION DEVICE ADJUSTMENT: (on models which have decompression)

The decompression device must be adjusted every time the rocker arm cover is removed or tightened.

       1.   Remove cover over flywheel timing mark inspection hole. (Tool B). No decompression lever
            on models 12 and 35.

       2.   Turn crankshaft over by hand being careful not to damage the spline on end of crankshaft,
            until flywheel mark 1-TC is aligned with the pointer on the wall of the inspection hole.

       3.   Remove decompression covers from top of rocker arm cover over number 1 cylinder. (Tool
            A).

       4.   With the alignment of the pointer and flywheel mark 1-TC the no. 1 cylinder decompression
            adjustment can now be accomplished.

       5.   Pull and hold lever to full decompression position.

      6.   Working through the access hole, loosen the lock nut with a wrench (tool A) and back the
           adjusting screw off until no contact is made on the rocker arm (Using screw driver).

      7.   Now tum adjusting screw in until first contact is made, continue to tum screw in (1) turn.

      8. Lock the screw in this position with the lock nut. Observe the position of slot in screw prior
           to locking nut, recheck after tightening lock nut.
      9. The above stops are to be followed to adjust the decompression for all remaining cylinders.
           After aligning the respective flywheel marks (2-TC, 3-TC, etc.). Adjustments can be made     as
           described in steps 3 thru 7 above.

     10. After all necessary adjustments have been made, be sure to replace and secure all access
           hole covers and the flywheel inspection hole cover.

 FUEL SYSTEM:

The fuel system utilizes either an electric or mechanical fuel pump, fuel filter, fuel injection pump with
injectors and fuel lines. Any fuel not used by the injectors is returned through fuel return lines from the
rear most nozzle to the top of the fuel supply tank.

ALL MODELS AFTER 1986 HAVE ELECTRIC FUEL PUMPS

The canister type fuel filter should be changed each season before the engine is placed back in ser-
vice or more often based on engine usage.

The engine operates on No.2 diesel fuel only and care should be taken to see that no water or dirt
enters the fuel system.

Clean fuel is very important to a smooth, trouble free running engine. Add a fuel additive to prevent
algae growth.

BLEEDING THE FUEL SYSTEM:

It will be necessary to bleed the fuel system to achieve a steady air free flow of fuel if any of the follow-
ing have occured: Models M-12, M2-12, M3-20, and M4-30 have self bleeding fuel systems.                     .

      1.   Running out of fuel.

      2.   If fuel shut off valve is left closed and engine runs out of fuel.

      3.   Replacing fuel filter.

      4.   Fuel injector nozzle or injector pump repair.

      5.   After repairing or replacing any fuel line.

      6.   Before putting engine back into service in the spring, if fuel system has been drained.

      7.   Replacement of electric or mechanical fuel pump.

      8.   Any time air is permitted to enter the fuel system.

BLEEDING PROCEDURE:

Be sure to have some means available to catch or absorb any fuel escaping during the bleeding pro-
cess so that it will not accumulate in the engine compartment or bilge.

      1. Be sure there is a sufficient supply of fuel in the fuel tank.

      2.   Open the fuel shut-off valve at the tank.

      3.   Start the electric fuel pump by turning the ignition key to the "ON" position on models 18,
           20, 25, 30, 50, all models after 1986.

      4.   Model 15 has a mechanical fuel pump. Therefore with decompression on, turn engine over
           with starter. Crank at 10 second intervals while doing steps #5 and 7.

      5.   Slowly loosen the air bleed plug on the fuel filter, letting air escape until an air free flow of
           fuel is evident. (1986 models see item 7).

      6.   At this time, tighten the air bleed plug on the filter.

      7.   Slowly loosen the air bleed plug on the injector pump, letting air escape until an air free flow
           of fuel is evident. Units with a self bleed return valve, open for a short period then start
           engine, as soon as engine runs smooth close valve. Model-12 has continuous fuel bleeding.

      8.   At this time, tighten the air bleed plug or knurled knob on the injector pump.

      9.   The fuel system should now be properly bled and ready for operation.

Refer to starting instructions before attempting to start the engine after bleeding the fuel system.

           CAUTION: Excessive cranking with sea cock valve open can cause water accumulation in
                    the muffler and possibly back up into the engine. Drain muffler as needed.

FUEL INJECTORS:

Fuel injectors should be removed and taken to a qualified diesel engine repair center to be tested for
leakage and spray pattern, if poor engine performance such as loss of power, rough or uneven runn-
ing, sudden notice of dark exhaust, or engine becomes hard to start.




                                                         24
REMOVING INJECTORS:

      1.   Clean the area around the injectors before removing.

      2.   Loosen nuts holding fuel lines to injector pump and injector nozzle and remove fuel lines
           (fool C).

      3.   Loosen "nuts on return line adapters "and remove adapters (fool C.)

      4.   Loosen injectors (using Tool E) and remove injectors.

REPLACING INJECTORS:

      1.   Check to be sure contact surfaces and area around injectors is clean.

      2.   Replace injectors in the same cylinder from which they were removed.

      3.   Torque required to properly seat the injectors will be between 43 and 58 ft./lbs.

      4.   Replace fuel return lines and secure nuts.

      S.   Replace all fuel lines and secure all nuts.

      6.   After all injectors, fuel lines and hoses have been replaced and are secured, the fuel system
           will have to be bled. (Refer to bleeding instructions in this manual. (P-27)

The fuel injection pump has been set at the factory and should need no adjustment. Any apparent pro-
blem with the pump should be referred to a qualified diesel mechanic or to a Universal Diesel dealer as
advised.

           NOTE: NO WARRANTY COVERAGE WILL BE GRANTED IF ANY OF THE FACTORY SET
                 AND SEALED FUEL AND MAXIMUM R.P.M. ADJUSTMENTS ARE ALTERED.

OIL FILTER CHANGE:

After draining engine oil and before refilling with new oil, the oil filter should be changed.

      1.   Unscrew old filter. If it will not loosen, use a speCial oil filter removal tool.

      2. Take care to catch any escaping oil so that it will not accumulate in the engine compartment.

      3.   When installing new filter, moisten the rubber seal with oil, screw new oil filter onto the
           threaded shaft and tighten it. Hand pressure is sufficient to tighten the filter.

      4.   Refill the crankcase with the correct grade and amount of oil as indicated by the full mark on
           dipstick.

      S.   Start the engine according to the starting procedure in this manual. Run only long enough to
           check for any oil leaks and stop engine.

      6. The oil level will have dropped by the amount of oil which enters the oil filter and by the
         amount which has distributed around the engine.

      7.   After engine has stopped and the oil level allowed to settle, recheck the oil level and fill as
           required.

UNIVERSAL RECOMMENDS THAT YOU USE FACTORY REPLACEMENT FILTERS. THE USE OF
OTHERS MAY VOID THE ENGINE WARRANTY.

SEA WATER PUMP:

Your engine is equipped with a rubber impeller type sea water pump.

     CAUTION: DO NOT RUN PUMP DRY AT ANY TIME OR YOU WILL DAMAGE THE IMPELLER,
              CAUSING ENGINE TO OVERHEAT.

You can use methyl alcohol based anti-freeze compounds such as Zerex, Shell Zone, Pyro Permanent,
Permagard and Dowgard.

REPLACEMENT OF SEA WATER PUMP IMPELLER:

      1.   Be sure engine is stopped. Turn off sea water inlet valve.

      2.   Loosen and remove the pump cover screws.

      3.   Tap cover on side to loosen, being careful not to damage cover gasket and remove cover.

      4.   At this time be careful not to pull the pump shaft forward or out of its present position. If the
           shaft does come forward during the changing of impeller, it will be necessary to remove
           complete pump.                                                               .

      5.   Remove the snap ring located on the end of shaft in center of impeller, with shaft held in
           place.

      6.   The impeller can now be pulled off the pump shaft. Be sure to hold shaft in place with a
           screwdriver or etc., when removing the impeller.

      7.   Replace with the new impeller by rotating. (You can lubricate impeller with vaseline or oil
           prior to installing.) This will also prevent burning of new impeller when first starting engine.

      8.   Replace snap ring, being sure it is in the groove all the way around.

      9.   Replace gasket and cover (oil inside of cover).

     10. Replace the cover screws and tighten evenly.

     11. Open sea water inlet valve, check for leaks.

     12. Engine can now be started, check engine temperature.



                                                      26
NOTE: IF DURING IMPELLER REPLACEMENT THE PUMP SHAFT CAME FORWARD, IT
COULD HAVE COME OUT OF THE GROOVE AND DRIVE ADAPTOR. IF SO, YOU MUST COM-
PLETE THE FOLLOWING. NOTE - ON NEWER UNITS WITHOUT A MOUNTING SPACER BET-
WEEN THE PUMP AND ENGINE BLOCK YOU DO NOT HAVE A DRIVE ADAPTOR TO BE CON-
CERNED ABOUT. HOWEVER, YOU MUST ALIGN THE SHAFT TANG AND THE DRIVE
GROOVE WHEN REINSTALLING THE PROPELLER SHAFT.

 1.   Loosen and remove the two capscrews holding the pump body to engine.

 2.   Slowly move pump away from engine as the adaptor will come out.

 3.   Complete the replacement of impeller as noted above.

 4.   The pump shaft will now be protruding through the body mounting flange.

 5. -Place the adaptor on to the pump shaft aligning the pin on the groove. On later models this
     may not be present, the pump may mount direct to engine block.

 6.   Align the slot on the other side of adaptor with the drive shaft in engine and place pump on
      engine.

 7.   Hold in place and start the two mounting capscrews. TIGHTEN FINGER TIGHT SO PUMP
      IS FREE TO MOVE AND ALIGN ITSELF. ON 1987 MODELS THE PUMP HAS A PILOT
      FOR SELF ALIGNING, JUST MOUNT AND TIGHTEN.

 8.   Open sea water valve and start engine at idle. This will align pump to the drive and adaptor.

 9.   Stop engine - now tighten capscrews carefully.

CAUTION: BE VERY CAREFUL DUE TO V-BELT MOVING ON FRONT OF ENGINE.

10.   Feel the bearings to make sure they ·are not hot; they are located in the center of pump
      body.

11.   Alignment of pump can also be accomplished by turning engine over with the starter while
      decompression lever is in the open position, approximately 5 to 10 revolutions. Release
      starter button and decompression lever - tighten water pump screws.

NOTE: THERE ARE TWO TYPES OF SEA WATER-RUBBER IMPELLER PUMPS USED. ORBER-
DORFER PUMP HAS 4 SCREWS SECURING COVER TO PUMP BODY AND SHERWOOD
PUMP WHICH HAS 6 SCREWS SECURING COVER TO PUMP BODY. NOTE WHICH PUMP
YOU HAVE ON COVER OF THIS MANUAL. IT IS RECOMMENDED TO HAVE A SPARE IM-
PELLER AND COVER GASKET ON BOARD AT ALL TIMES.

ORBERDORFER IMPELLER NO. 295628                        COVER GASKET NO. 295626

SHERWOOD IMPELLER NO. 287439                     COVER GASKET NO. 295745

CAUTION: DO NOT RUN PUMPS DRY OR WITH SEA INLET VALVE CLOSED. LACK OF
WATER WILL CAUSE EXCESSIVE HEAT BUILD UP DAMAGING OR DESTROYING THE RUB-
BER IMPELLER, AND ENGINE WILL OVERHEAT.

IF VANES COME OFF IMPELLER THEY MUST BE LOCATED AND REMOVED TO INSURE
THEY ARE NOT BLOCKING OR RESTRICTING THE COOLING WATER FLOW IN THE ENGINE,
HOSES, OR FITTINGS.                 \

NEW STYLE PUMPS HAVE A PILOT AND CAN BE MOUNTED AND BOLTED TIGHT WITHOUT
TURNING THE ENGINE OVER.

 8.   Enters thermostat which remains closed during warm up, permitting a small amount of water
      to enter exhaust system for cooling and overboards.

 9.   As engine temperature rises the     thermostat starts to open, permitting hot water to enter ex-
      haust line. At the same time the    same amount of cool sea water is drawn in by the pump to
      replace the discharge hot water.    This is done through the mixing tee which is located below
      engine (or water line) to prevent   air from entering the system.

10. There may be some fluctuation in engine temperature until engine stabilizes.

11.   In areas of cold inlet say 50°, you may notice some movement from 135° to 155° as engine
      R.P.M. are changed. This is less noticeable with warmer inlet water. The reason being that
      the colder water causes thermostat to react faster than engine temperature stabilizes.

12.   It may appear at first that no water is being pumped overboard with the exhaust gases.
      However as long as water temperature is within operating range (135° - 155°), there is a flow
      of water being pumped overboard which may be noticed ·only as a fine mist. This will con-
      tinue until the thermostat directs the water flow overboard to allow for greater intake of
      cooler sea water.

FRESH WATER

   1.   Coolant (fresh water with antifreeze) is introduced into the system from the coolant section of
        exhaust manifold by removing pressure cap and filling manifold tank to within one inch of
        lower rim of fill port.

   2.   Fresh water engine driven circulating pump moves coolant from heat exchanger through
        engine block circulating pump and thermostat back through exhaust manifold into heat ex-
        changer to be cooled.

        The manifold serves as the engine expansion tank to allow for expansion of coolant as it is
        heated. You also fill the system at this point. In some cases when hot water heaters are in-
        stalled an expansion or surge tank may be required to prevent air from entering the system.

        Should your engine overheat, first check coolant level to make sure it is not low which would
        cause air locks to develop. If air does enter the system, it may require a couple of fillings to
        remove the air pocket. A momentary increase of engine R.P.M. to approximately 2800 to
        3000 R.P.M. may aid in moving the air from the system. In some cases it may require dOing
        this 2 or 3 times. Do this just as you notice the temperature starting to rise above normal.

 A.   DESCRIPTION:

      The Hurth transmission housing is made of a high strength aluminum alloy that is resistant to sea
      water. The transmission is equipped with shaved and case hardened helical gears and with shafts
      mounted in heavy-duty roller bearings. Forward and reverse is accomplished by a mechanical fric-
      tion clutch.

      Gear shifting is mechanical and requires only a minimum effort on the gear lever. Precision set-
      ting or readjustment of the shifting control (Morse or Teleflex) is not required.

      The transmission is designed to permit reversing at full engine speed. TO BE USED ONLY IN
      THE EVENT OF AN EMERGENCY!

 B.   SERVICING:

      The transmission is filled with Type AFT or DEXRON II transmission fluid at the factory during the
      engine load test.

            Recheck and fill the gear box with the prescribed oil up to the FULL INDENTED RING
            MARK ON THE DIPSTICK (approximately 1/4" up from bottom of stick). Do not overfill.

            When checking the oil level, DIPSTICK TO BE INSERTED ONLY - DO NOT SCREW IN.

            Tighten the dipstick after adding oil or checking the oil level.

FULL 1.     Placing in service after storage.


            If the transmission was completely filled with oil for storage and preservation, make sure to
            drain the excess oil to the proper level. Use new oil if necessary.

       2.   Oil quantity.      Transmission Fluid           Quantity
                                   HBW50            0.29 Quarts (O ..30 Liters)
            Approximately          HBW100           0.33 Quarts (O.35 Liters)
                                   HBW150           0.59 Quarts (O.56 Liters)

            (General Motors) and M2 C33 G (Ford).

            ALWAYS USE THE SAME GRADE AND TYPE OF OIL WHEN ADDING OR CHANGING OIL.

            WARNING: ADDITIVES SUCH AS MOYBDENUM SULPHITE OR THE LIKE MUST NOT BE
                     CONTAINED IN THE OIL UNDER ANY CIRCUMSTANCES.

 C.   MAINTENANCE:

       1. Oil level in the transmission should be checked weekly.
          Oil level: See Servicing.

       2.   Changing oil.

            Change oil after first 25 hours of operation. Then change every 300 hours of operation, or at
            least at intervals of once a year or season.

       3.   Placing transmission in storage.

            If the transmission is put out of operation for long periods of time under unfavorable en-
            vironmental conditions, it should be protected against corrosion by filling it completely with oil
            of the same, grade and type. Otherwise, it should be operated briefly, with a good oxida-
            tion inhibiting oil to allow the agent to contact all parts of the gearbox.

                                                                                  REVISED NOVEMBER 1997
D.   GENERAL INFORMATION:

     1.   General

          If the transmission is being painted, care should be taken to protect the oil seals at the out-
          put shaft in back of the coupling. Make sure the venting hole on the oil filter screw is not
          covered with paint.

          The assembly - (engine/transmission) should be flex mounted in the boat to avoid distortion
          of the transmission housing.

     2.    Angle of installation

          The angle of installation must not exceed 150 in relation to the water line in operation. See
          illustration (Figure 13-A)

     3.   Operating temperature

          Proper ventilation of the engine and transmission compartment should be insured. The
          operating temperature of the transmission oil should not exceed 2500 F. (130 0 C)

     4.   Flexible couplings (Optional)

          The flex coupling between engine coupling and propeller shaft should be designed to absorb
          bending stresses to compensate for minor angular deviations after installation.

          Coupling alignment must be checked with the boat in the water, both rigid and flexible.

     5.   Gear shifting

          Shifting requires little effort, therefore, both the single and dual lever control works well on
          this transmission. Dual lever is considered the standard in most cases.

          Shift lever: Upon loosening the retaining screw, the shifting lever can be rotated as required
          to meet the control cable connection. The operating cable or rod assembly should be posi-
          tioned perpendicular to the shifting lever in its neutral position (Figure 13-8).

          The shifting travel, measured at the pivot pOint of the shifting lever, must be at least 1-3/8"
          (35mm) from neutral to forward and neutral to reverse position. Longer shifting movements
          have no detrimental effect on the transmission (Figure 13-8), however, insure lever travels
          beyond the detent in both directions when shifting.

          When shifting transmission, engine R.P.M. should be returned to idle, then shift transmission
          firmly from one direction to another. A slight pause in neutral will allow propeller to slow and
          add life to transmission.

          When running the engine to charge batteries in neutral, engage transmission for 1 or 2
          minutes every 2 or 3 hours to lubricate all internal parts.

          To lock the propeller vertically in line with the keel, mark the coupling and POSITION GEAR
          IN REVERSE. This will prevent slippage and damage to the clutch.




                                                     37
CAUTION: THE CABLE MUST BE MOUNTED TO THE SHIFT LEVER AT A 90° ANGLE TO
         INSURE EQUAL TRAVEL FROM NEUTRAL TO FORWARD AND NEUTRAL TO
         REVERSE (See Fig. 13-B).

CAUTION: TRANSMISSION MUST BE LEFT IN NEUTRAL WHEN SAILING, DO NOT
         LEAVE IN FORWARD GEAR WHEN SAILING WITHOUT POWER AS IT WILL
         DAMAGE GEAR.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
