This manual has been compiled to provide the user with important information and
recommendations to ensure a trouble free and economical operation of the engine.

For further advice or technical assistance, application should be made to BETA MARINE LIMITED
or its distributors.

All information and recommendations given in this publication are based on the latest
information available at the time of publication, and are subject to alteration at any time. The
information given is subject to the company's current conditions of Tender and Sale, is for the
assistance of users, and is based upon results obtained from tests carried out at the place of
manufacture and in vessels used for development purposes. We do
not guarantee the same results will be obtained elsewhere under
different conditions.




ENGINE IDENTIFICATION
NOTE: In all communications with the distributor or Beta Marine,
the engine number, type, and W.O.C. number must be quoted.

The engine serial number is stamped above starter motor on the                         K12345
port side of the engine, and is shown on the rocker cover label.
                                                                                       43bhp 2800rpm


INITIAL RECEIPT OF THE ENGINE
A full inspection of the engine must be made immediately on
delivery to confirm that there is no damage. If there is any damage then write this clearly on the
delivery note and inform your dealer or Beta Marine within 24 hours.


ENGINE STORAGE
The engine must be stored in a dry, frost free area and this is best done in its packing case. If
storage is to be more than six months then the engine must be inhibited (contact your dealer or
Beta Marine). Failure to inhibit the engine may result in the formation of rust in the injection
system and the engine bores, this could invalidate the warranty.

IMPORTANT CHECKS PRIOR TO INITIAL USE
1. Generally, a new engine has the oil and anti-freeze removed after the works test. Fill the engine with the correct oil and
   anti-freeze (see sections on ENGINE OIL and COOLING). Check gearbox oil level - see separate operator's hand book.
2. Ensure the engine is free to turn without obstructions.
3. Ensure battery is fully charged and connected (the isolator is in the 'ON' position).
4. Ensure Morse speed and gearbox cables are fitted correctly and that cable travel lengths are correct.

   Gear selection lever ­all mechanical gearboxes: care must be taken to ensure that the remote control cable is
   adjusted so that the selector lever on the gearbox moves FULL travel and brought "hard up" against its end stop in
   both directions. Failure to achieve the correct adjustment will reduce efficiency
   of the clutch and may cause slippage at low revs. Warranty will not be accepted
   on gearboxes returned in the warranty period for failure due to incorrect
   adjustment.

5. Ensure engine is out of gear with 1/3 throttle - see single lever control instruction
   manual.
6. Open the fuel stopcock and bleed the fuel water separator of air as shown in
   manufacturers literature.
7. Fuel should now be at the fuel lift pump, see diagram 1a, open the sea cock

INITIAL STARTUP AND BLEEDING THE SYSTEM                                                              Diagram 1a
(a) Open fuel bleed screw on fuel filter assembly by 11/2 turns. See diagrams 1a & 1b.
(b) Move hand priming lever on fuel lift pump up and down until fuel with no
    bubbles comes out of the bleed screw.
(c) Shut/tighten the bleed screw. Clean area thoroughly with tissue paper.
(d) Continue to hand prime for 30 seconds to push fuel through the fuel pump.
(e) Start engine (see normal starting).
    Note the engine may have to be turned over with the starter for a few seconds
    before it fires. Do not run the starter for more than 20 seconds. If the engine
    has not started after 20 seconds then disengage the starter and continue to
    hand prime for a further 30 seconds, then repeat.
(f) If engine does not start after 3 attempts then allow 5 minutes for the starter to                Diagram 1b
    cool down before repeating (a) to (e).
    Note: The starter windings can be burnt out with continuous cranking

CAUTION
To avoid personal injury:
· Do not bleed a hot engine as this could cause fuel to spill onto a hot exhaust manifold creating a danger of fire.
· Do not mix gasoline or alcohol with diesel fuel. This mixture can cause an explosion.
· Do not get diesel on the flexible mounts ­ they will deteriorate rapidly if soaked in diesel.
· All fuel must be removed from skin to prevent infection.

alternator warning lights are still on, then increase engine speed to excite the alternator - then return to
idle. The battery charge lights should then go out. The run light will remain on (green lamp).
Check for sea water flow. If no flow then SWITCH OFF IMMEDIATELY AND CHECK SEA WATER SYSTEM.

STOPPING
Every propulsion engine is fitted with a stop solenoid which is energised to stop. To stop engine simply press stop push
button, hold in until engine stops, then turn key from `RUN' to `OFF' position.
When leaving the boat for an extended period,
· Turn off sea-cock (heat exchanger cooled engines).
· Turn off battery isolator.
Do not turn the key to the off position when the engine is running. This will damage the alternator.

*WARNING
Do not leave the key in `HEAT' position for more than 15 seconds - this will damage the heater plugs and eventually
lead to poor starting.
Do not depress stop button for more than 10 seconds as this will lead to overheating and failure of the solenoid.
                                                                                                                   Speed
Notes for all panel types:                                                                                         Lever

Do not depress the stop button for more than ten seconds as this will lead to
overheating and failure of the solenoid.

This range of engines are equipped with a mechanical stop lever in the event of
electrical system failure. This lever is located on the starboard side of the engine
above the speed control lever. See illustration right:                                                             Stop

CHECKING ENGINE OIL LEVEL                                                                            in here
For quantities of oil required see section marked `Technical Specification', Page 4
When checking the engine oil level, do so before starting, or more than five
minutes after stopping.
1. To check the oil level, draw out the dipstick, wipe it clean, re-insert it, and draw
    it out again. Check to see that the oil level lies between the two notches.
2. If the level is too low, add new oil to the specified level - Do not overfill

                                                                                                     Fig. 2a
IMPORTANT
When using an oil of different make or viscosity from the previous one, drain old         Dipstick

oil. Never mix two different types of oil. Engine oil should be changed after first
50 hours running time and then every year or every 250 hours if sooner. Oil
filter is a cartridge type mounted on the starboard side of the engine.

CHANGING ENGINE OIL

(1) Run the engine for 10 minutes to warm up the oil.

(2) Your engine is provided with a sump drain pump. Unscrew the end cap on the
                                                                                                     Fig. 2b
    end of the pump, turn the tap to `on'. Use the hand pump as shown to pump
    out the oil into a bucket. Turn the tap to off position and replace end cap. See
    diagram 2c.                                                                           Sump
                                                                                          Pump

(3) Unscrew the oil filter and replace with a new one. See diagram 2d.

    Note: It is best to have a plastic bag wrapped round the filter to catch any oil
    left in the system. (Always keep your bilges clean!) Before screwing in the new
                                                                                          End
    filter spread a thin film of oil round the rubber gasket to ensure a good seal        Cap
    and screw in ­ hand tight.

(4) Fill the engine with new oil as described on the previous page.

(5) Run the engine and check for oil leaks.
                                                                                                     Fig. 2c

CHECKING GEARBOX OIL LEVEL
(1) The gearbox is fitted with a dipstick and oil filler plug, see fig 2e.
(2) Each engine is supplied with a gearbox operators manual which specifies
    the type of lubricating oil to be used, the capacity and frequency of
    changing of the oil.
(3) New engines are normally supplied with the gearbox topped up with
    lubricant but Check the level before starting the engine for the first time.
(4) The oil can be changed via the drain plug at the bottom of the box or
    sucked out with a hand pump via the filler plug.
                                                                                            Fig 2d - oil filter removal

Note: ATF is Automatic Transmission Fluid


FUEL SYSTEM          (see page 24 for a typical installation)

IMPORTANT
· Always fit a fuel/water separator in the fuel supply system. Water in the fuel can seriously damage the injection
  system.
· If a fuel supply shutoff valve is fitted do not use a taper tap, only use a ball valve tap. The ball valve type are more
  reliable and less likely to let air into the fuel system.
· Be sure to use a strainer when filling the fuel tank. Dirt or sand in the fuel may cause trouble in the fuel injection
  pump.
· Always use diesel fuel.
· Do not use kerosene, which is very low in cetane rating, and adversely affects the engine.
· Be careful not to let the fuel tank become empty, or air can enter the fuel system, necessitating bleeding before
  next engine start.
· The fuel lift pump will only lift fuel through 0.25 metres. If this is insufficient then an electric fuel lift pump must
  be fitted. Drawing 202-06421, illustrating recommended wiring for this pump can be supplied upon request.


FUEL FILTER REPLACEMENT
1. The fuel filter is a spin on type. Remove by turning anti-clockwise when
   viewed from below.
2. Replace the fuel filter cartridge every 750 hours or every 2 years. See fig. 2g.
3. Apply fuel oil thinly over the gasket and tighten into position - hand tight.
4. Bleed as detailed - see initial start up.
5. Check for leaks.
6. Do not get fuel on the flexible mounts.
                                                                                                      Fig. 2g

HEATING EXCHANGER COOLED                                                    Heat Exchanger Cooled
Fresh water circulates through the engine and on to a heat
exchanger where it is cooled by sea water which is pumped
through the cooling tubes. The sea water is then injected into
the exhaust system (see diagram).


FILLING THE FRESHWATER SYSTEM
New engines are supplied with the freshwater drained off. The
following instructions must be followed to fill the system.
                                                                                    Drain
(a) Mix up in a clean bucket a 33 to 50% anti-freeze to                             Tap
    freshwater solution (see page 10). For the volume required
    see technical specification page 4.

(b) Check that the drain tap or plug is turned off. (see fig 2l)

(c) Fill engine with freshwater/anti freeze solution through the top
    of the heat exchanger or header tank with the filler cap
    removed. (see fig 2m).

(d) Fill header tank to the top of the filler neck and replace cap.
    Press down firmly on filler cap and hand tighten in a clockwise
    direction.

(e) Run the engine for 5 minutes on no load (out of gear) and
    check coolant level. Top up as necessary.

(f) Check system for leaks.

(g) If a calorifier is fitted care must be taken to see that this is also
    full of coolant and all the air is expelled. (See calorifier fitting                      Fig. 2l
    notes under Section 3).

(h) Run the engine on one third load for 15 minutes, preferably with the boat
    tied up. As the system warms up coolant may be expelled from the
    overflow pipe into the bilge. Stop the engine and allow the engine to cool
    down before removing the pressure cap and top up the coolant to 1" below
    the filler neck.


IMPORTANT
Removal of the pressure cap when the engine is hot can cause severe injury
from scalding hot water under pressure. Always allow the engine to cool and
then use a large cloth when turning the cap anti-clockwise to the stop. This
allows the pressure to be released. Press firmly down on the cap and continue
to turn anticlockwise to release the cap.

(i) Repeat (h) if coolant level is more than 1 inch below the base of the filler
    neck when the engine has cooled down.

(j) Run engine on 2/3 full load for 20 minutes, check for leaks and repeat (i).                         Fig. 2m


(k) Anti-freeze solutions should be drained off every 2 years and replaced with a new solution.

Note: When draining fresh water system, ensure the engine has cooled sufficiently to prevent scalding from hot
pressurised water. Prior to draining a cold engine, remove the filler cap from the header tank and then open the
water drain tap. This allows the water to drain freely from the system.




                                                               9
Yachts and Launches with Heat Exchanger Cooling
It is essential that a 33% to 50% anti-freeze/water mixture is used. This not only stops freezing up in winter, but it
prevents overheating and corrosion.
The warranty is invalid unless the correct ratio is used.
Concentration of ethylene should not exceed 50%.

The anti-freeze in the fresh water system enables the boiling point of water to rise to 124°C with a 13 psi pressure
cap fitted. The water temperature alarm switch will however be activated at 95° to 100°C. If no anti-freeze or a very
weak solution is used, then the water temperature switch may not be activated before coolant is lost.


SEA WATER PUMP AND COOLING SYSTEM
(Heat exchanger-cooled engines)

CAUTION
Before working on the sea water system ensure that the sea cock is in the off
position.

(1) It is very important that the correct sea water flow is maintained to cool the
    closed circuit system of the engine. The key component in this system is the sea
    water pump impeller. This should be checked every year by removing the
    circular plate (see fig. 2h).

(2) Withdraw the rubber impeller from its drive shaft as shown. See diagram 2i.

(3) Check impeller for cracks in the rubber, excessive wear or lost vanes. Replace                 Fig. 2h
    with a new impeller as necessary.

   Note: If any pieces of rubber impeller are missing then they must be found as they
   are most likely to be trapped in the entrance to the heat exchanger cooling stack. See
   `Cleaning Tube Stack'.


CLEANING THE HEAT EXCHANGER TUBE STACK AND REPLACING
WASTING ZINC ANODE

(1) The wasting zinc anode should be checked every six months and replaced every year
    or as necessary. The anode is attached to the bolt inserted in the end cap of the heat             Fig. 2I
    exchanger. See Fig 2j. On most engines this is on the aft end.

(2) Unscrew the bolt and replace the complete unit with a new one.

(3) Check for leaks.

(4) It is possible for fine sea weed and other debris to get past the inlet filter and
    into the tube stack. This should be removed and cleaned. See fig. 2k.

(5) Drain off coolant into a bucket.

(6) Unscrew the 2 end cap retaining bolts (one each end of the tube stack). Remove       Zinc       Fig. 2j
    the `O' rings and pull out tube stack. Clean tube stack and end caps.                Anode

(7) Re-assemble using new `O' rings. Do not overtighten end cap bolts and make
    sure the tube stack is the right way round.

(8) Re-fill engine with water/anti-freeze solution and run engine up to temperature
    to check for leaks.

65 AMP ALTERNATOR (Heat Exchanger Cooled)

WARNING

Belt tension must only be checked with the engine switched off.

(1) On heat exchanger cooled engines a single 65 amp is fitted as standard.
    This alternator is adjusted as follows.

(2) The belt tension is adjusted by swinging the alternator outboard as it
    pivots on its support bolts.

(3) With the engine stopped, loosen the support bolts and the link adjusting
    bolt.

(4) Push alternator outboard to tension and tighten link bolt. Check that the
    depression of the belt at position shown is approximately 1/2" or 12 mm
    when pushed down firmly by thumb. Tighten support bolts.

(5) Belt tension should be regularly checked especially during the first 20
    hours of running in a new belt, as stretching occurs.



100 Amp alternator (option):
The same method applies as outlined above, but final tensioning must be by
hand only. Over tensioning will cause premature failure of components.




AIR INTAKE FILTER
These engines are fitted with an air intake filter which should be checked every season and changed every 2 years
or sooner if badly clogged. If badly clogged check more often

MAINTENANCE - ELECTRICAL

WARNING

Under no circumstances should the battery be disconnected or switched off when the engine is running. This will
seriously damage the alternator



PANELS AND WIRING
See installation notes, page 27.


General maintenance
(1) The panel must be protected from rain and sea water, see installation. Sea water entering the key switch will
    eventually cause corrosion and could result in the starter motor being permanently energised and burning out.
    Spray key switch every month with WD 40 or equivalent.

(2) Check batteries for acid level and top up if required. For low maintenance and `gel' batteries see manufacturers
    instructions.

(3) Loose spade terminal connections are the most common cause for electrical faults - check on a regular bases
    (see maintenance instructions).


WINTERISING AND LAYING UP
Heat Exchanger Cooled Engines Left Afloat And Ashore

(a) The engine oil and oil filter should be changed at the end of the season rather than in the spring. See section 2.

(b) The closed circuit system should contain a 30 to 50% solution of anti-freeze to water (this also applies to warm
    and tropical climates).

(c) For cold climates where the air or water temperatures can fall below 3°C, the sea water circuit must be protected
    in addition to the fresh water system. This is best achieved as follows:

   (i)   Close the inlet seacock to the engine (engine stopped).

   (ii) Disconnect the sea water inlet pipe and dip it into a small bucket containing 50/50 anti-freeze solution.

   (iii) Start the engine (out of gear) and run for 5 to 10 seconds until the anti-freeze is used up and can be seen
   coming out of the exhaust outlet.

   (iv) Shut engine off and reconnect the inlet pipe to the seacock.

   The sea water or raw water circuit is now protected by anti-freeze.

(d) Ensure instrument panel is well protected and give the key switch a spray of WD 40 or equivalent.

(e) With the engine stopped, disconnect the battery (always disconnect the negative cable first and re-connect the
    negative cable last) and take it ashore for trickle charging and top up as necessary. If AC power is available then
    this can be done on the boat.

(f) Fuel tanks should be kept full during the lay up period to eliminate water condensation in the tank. Water
    entering the fuel injection system can cause considerable damage.


LAYING UP ASHORE
(a) Change the engine oil before the boat is taken out of the water. Warm engine oil is much easier to pump

                                      TROUBLE SHOOTING
Beta diesels are very reliable if installed and serviced correctly, but problems can occur and the
following list gives the most common ones and their solution.

Problem: Engine does not start but starter motor turns over OK

Possible Cause                   Solution
No fuel:                         Turn fuel cock on and fill tank.
Air in fuel system:              Vent air (see initial start-up)
Water in fuel:                   Change fuel filter and bleed system.
Blocked fuel pipe:               Clean out and bleed system.
Fuel filter clogged:             Change filter and bleed system.
Fuel lift pump blocked:          Remove and replace.
Blocked injector:                Remove and clean.
Fuel return not fed back
to the tank:                     Re-route fuel return pipe.
Heater plugs not working:        Check wiring to the plugs, and replace plugs if they are burnt out.
Stop solenoid stuck in off
position:                        Check solenoid is free to return to run position.

Problem: Starter motor will not turn or turns over very slowly

Possible Cause                   Solution
Battery discharged:              Charge battery or replace. Check alternator belt tension.
Starter motor flooded with
sea water:                       Remove and clean or replace.
Wiring disconnected or loose:    Check circuit for loose connections.
Water in cylinders:              Incorrect installation. This is serious ­ check engine oil for signs
                                 of water (creamy-coloured oil). Ring your dealer.
Engine harness fuse blown:       Replace fuse (located by starter motor or above flywheel
                                 housing) and check for wiring faults



                                                 FUSE (If located by starter motor, usually it is
                                                positioned above flywheel housing at rear of
                                                engine)

                                                Note: For convenience, some engines are
                                                supplied with a spare fuse and holder attached to
                                                the main engine fuse holder.

Problem: Water in lubricating oil (keel cooled)
Possible Cause                     Solution
Oil goes "milky" due to water Check installation - has dry exhaust system been fitted correctly,
entering exhaust manifold and ensuring rain water cannot enter the exhaust port and run back?
then into the sump:           (See DRY EXHAUST SYSTEM) Change engine oil and run
                              engine for 10 minutes each time to eliminate any water. Get
                              injection pump checked by Service Agent.

Problem: Low oil pressure warning light comes on when engine speed reduced to tick over:
Possible Cause                     Solution
Faulty switch sender:              Replace.
Engine running too hot:            Check cooling water flow (see section 2 Cooling).

                                                    15
Problem: Engine overheats

Possible Cause                   Solution
Check coolant level:             Top up.
Insufficient sea water flow:     Clear blocked intake or filter.
Damaged or worn pump
impeller:                        Replace.
Blocked tube stack in heat
exchanger:                       Remove tube stack and clean ­ replace `O' rings.
Zinc anode flakes blocking tube
stack:                          Remove and clean tube stack as above.
Pressure cap loose:              Replace.
Switch sender faulty:            Replace.
Inlet sea cock is too small:     Replace (see heat exchanger cooled seawater inlet system in
                                 section 3).
High exhaust back pressure:      Must not exceed 3.1" of Hg.
Air locks in cooling pipe work
to keel cooler:                  Vent the system and top up coolant.
Keel cooler insufficient size:   Contact boat builder

GENERAL -HEAT EXCHANGE ONLY: The most common cause of overheating is insufficient
seawater flow due to a blocked intake (weed or a plastic bag!). If this happens then clear the
blockage. If the problem is not cured then check the system for sea water flow which should be
15 litres / minute minimum at 1,500 rpm as follows:
(a) With the boat tied up and out of gear run the engine up to 1500 rpm. *Hold a plastic bucket
over the exhaust outlet for 10 seconds and measure the amount of water collected. Multiply this
value by 6 to give the flow in litres/min. Repeat twice and take an average. If the flow rate is
noticably less than the 15 litre per minute minimum at 1,500 rpm, then:
(b) Check impeller in sea water pump - if worn replace.
(c) If impeller has a vane missing then this will be lodged either in the pipe to the heat exchanger
or in the end of the exchanger. This must be removed.
(d) Check flow again as in (a).
*Note: This operation must only be done in safe conditions, in port and with two assistants.
Working from a rubber dinghy is best. The person holding the bucket should take precautions
against breathing in the exhaust gasses.

Problem: Knocking noise

Possible Cause                   Solution
Propshaft touching gearbox
output coupling through split
boss or Type 16 coupling:        Adjust, giving correct clearance (10mm) between gearbox and
                                 propeller shaft
Flexible mount stud touching
engine bed:                      Adjust stud to clear
Drive plate broken               Replace / repair
Engine touching engine bed       Re-align engine / modify bed

Problem: Battery quickly discharges
Possible Cause                    Solution
High load and insufficient        Reduce load or increase charging time. Large domestic battery
running:                          banks subject to high electrical loads will take a considerable
                                  time to recharge from a single alternator.
Low electrolyte level:            Top up.
Fan belt slipping - black dust in
engine compartment, engine
compartment temperature too Adjust tension / replace belt with a high temperature type and /
high:                             or improve engine compartment ventilation.
Alternator defective:             Check with Agent.
Battery defective:                Replace.
Poor wiring connection:           Check wiring system.

Problem: Transmission noise

Possible Cause                    Solution
Check gearbox oil level:          Top up.
"Singing" propeller:              Check with supplier.
Drive plate rattle at tickover:   Check engine rpm (must be 850 rpm minimum in gear).
Worn drive plate:                 Change.
Propeller shaft hitting the       Move shaft back to give at least 5mm clearance (Type 12/16
Gearbox half coupling:            couplings only)
Problem: Vibration

Possible Cause                    Solution
Poor alignment to shaft:          The alignment must be accurate even if a flexible coupling is
                                  used (see section 3 ALIGNMENT).
Flexible mounts not adjusted
correctly to take even weight:    Check relative compression of each mount.
Flexible mount rubber perished: Replace. (Diesel or oil will eventually perish most rubbers.)
Loose securing nut on flexible
mount:                            Check alignment and then tighten the nuts.
Insufficient clearance between There must be at least 10% tip clearance between propeller and
the propeller tip and the bottom bottom of the boat (ie 10% of the propeller diameter as
of the boat:                     clearance). Refer to boatbuilder.
Loose zinc anode on the shaft: Tighten or replace.
Worn cutless bearing or shaft:    Replace.
Weak engine support/bearers: Check for cracked or broken feet.
Problem: Morse control cable will not fit

Possible Cause                    Solution
Fitting incorrectly               Cables are being fitted the wrong way around, switch over and fit
                                  the opposite way.

           Electrical fault finding & trouble shooting ­engines built after July 2005 only
The following chart is compiled to aid diagnosis of electrical faults, based on the Beta 10-90hp range of
engines. If your engine was built before July 2005, contact Beta Marine for the relevant electrical
trouble shooting guide.
Standard sea specification engines (heat exchanger cooled) are supplied with a single alternator,
mounted port side, supplying power to starter battery and control panel.
Standard canal specification engines (keel cooled) are supplied with twin alternators:
·     1st alternator, mounted port side, supplying power to starter battery and control panel
·     2nd alternator, the standard mounting position for this is above the engine on the starboard side (or
                st
      below 1 alternator on 75 & 90hp), supplying power to the domestic battery system.
Both of these alternators work independently, if the domestic battery system is disconnected, the engine
will still run correctly but:
·     Domestic charge warning lamp will not function
·     Warning buzzer will remain on at all times
Standard control panels are supplied with four or five lamps:
Four lamp panels:         2a, 2ab'V', 2ab'V'W and 2b, these panels utilise bulbs inside sealed lamp
                          holders
Five lamp panels:         2ab'd' and 2c'd', these panels also utilise bulbs inside sealed lamp holders,
                          having an additional lamp for domestic battery charge
All Beta panels have the following warning lamps:                     (2a, 2ab'd', 2ab'V', 2ab'V'W, 2b, 2c'd')
Starter battery charge warning lamp                                              Red
·   High engine temperature warning lamp                                         Red
·   Low engine oil pressure warning lamp                                         Red
All panels also have:
·    Panel power on (this is not a warning lamp)                                 Green
In addition to above the domestic panels also have:                   (2ab'd', 2c'd' only)
·    Domestic battery charge warning lamp                                      Red
With keyswitch* in run position & engine off:
·     Red lamp for no starter battery charge should function
·     Red lamp for no domestic battery charge should function (Note: this will only function if a second
      alternator is fitted to the engine and connected to a charged battery)
·     Red lamp for high engine temperature should not function (when engine is cold / cool / warm). This
      lamp will only ever function if the engine is over temperature.
·     Red lamp for low oil pressure should function
·     Green lamp for panel power on should function
·     Buzzer should sound
* For operation of engines controlled with keyless panels refer to `Correct operation of keyless
panels' later in this section
When the engine is started, all the red warning lamps should switch off leaving just the green power on
indication lamp illuminated. The oil pressure lamp may take a few seconds to switch off and the charge
fail lamp may remain on until engine rpm is increased to approximately 1,000rpm if the engine was
started at tickover).
Before investigating any specific electrical problem, always check:
·   Connection between panel harness and panel loom. It must be clean, dry and secured with a cable tie.
·   Check the start battery is connected to the correct terminal on the starter motor.
                                                                                               nd
·   Check the domestic battery is switched on and connected to the correct terminals for the 2 alternator.
·   Battery connections, inspecting condition of cables from battery to engine. If in doubt measure the voltage at
    the engine.
·   If alternator charge problem, measure battery voltage with engine off
    and again with engine running, if there is an increase alternator is
    functioning correctly, if not refer to check list.
                   Typical start battery positive

                   Typical start battery negative

Note: The two way plug on panel loom will only have a
corresponding socket to connect into from the engine if a 2nd
alternator is fitted which requires this connection. Engines with
only one alternator do not utilise this connection.

Electrical ­Correct operation of keyless panels
These panels control the engine with three water resistant push buttons instead of a keyswitch, which
are less prone to damage and corrosion from sea water spray than a keyswitch.
To operate the engine:
1. Press and hold `HEAT' button for ten seconds maximum
·    Red lamp for no starter battery charge should function
·    Red lamp for high engine temperature should not function (when engine is cold / cool / warm). This
     lamp will only ever function if the engine is over temperature.
·    Red lamp for low oil pressure should function
·    Green lamp for panel power on should function
·    Buzzer should sound
2. Press `START' button and hold in position until engine fires (see initial start-up section for maximum
     time starter can be operated). Release button (when engine has started)
·     All red warning lamps should extinguish and buzzer should stop sounding. The oil pressure lamp
      may take a few seconds to switch off and the charge fail lamp may remain on until engine rpm is
      increased to approximately 1,000rpm if the engine was started at tickover.
·     Green lamp for panel power on should still function
3. To stop the engine press the `STOP' push button, hold in until engine stops. This button also
     switches the power off to the gauges, engine and power on lamp.
4. To re-start the engine, simply repeat steps from `1' above, there is not need to switch battery
     isolators off whilst remaining on board.
5. If leaving the boat, isolate start battery from engine and panel, to prevent accidental start up of
     engine.

Electrical fault finding ­Non Beta Panels

Engines can be supplied wired up to suit VDO switch senders, usually fitted to a non-Beta control panel.
If so refer to our wiring diagram 200-60971/01 (also part number for replacement harness)
·   Loom is configured differently in the 11-way plug to accommodate the extra wiring.
·   Small brown wire (battery sensed alternator feed) fitted with bullet connection beside harness plug.
·   Oil pressure & water temperature switch / senders fitted to engine, requiring individual connections
    for driving gauges & warning lamps.

Electrical fault finding ­Extension harnesses
Some installations require one of the panel extensions 11 way connectors to be removed to allow the
cable to be passed through bulkheads etc. If any panel problems are experienced after this may have
been carried out, visually check all 11 way connections on engine harness to panel extension (and
panel extension to panel on 2c deluxe) to ensure wire colours to each terminal match up to the
correct colour in its corresponding terminal. Extra attention must be given to black (ground) and
black/blue (tacho), also brown (switched positive to alternator) and brown/yellow (charge fail) as these
connections are harder to distinguish between in poorly lit areas. Whilst doing this check integrity of
each connection to ensure terminals have not become damaged. Once checked, re-fit cable tie around
each connection to keep them secure

Note: the above part numbers are suitable for earth return installations only (where battery negative
cable is connected directly to engine ground). For insulated earth (where battery negative cable is
isolated from engine ground) different harnesses, alternators, switches for oil pressure and engine
temperature will be required. If your application is wired as insulated earth return and the engine will not
operate correctly, always check starter battery negative is connected to the correct terminal on the
isolating solenoid. It should be connected to the terminal which is also used for all the small black wires,
NOT the terminal with the single black wire connected directly to engine ground.

craft it is impossible to give definitive instructions. Therefore Beta Marine can accept no responsibility for any damage
or injury incurred during the installation of a Beta Marine Engine whilst following these guidelines.
·       All engines shall be placed within an enclosure separated from living quarters and installed so as to minimise
        the risk of fires or spread of fires as well as hazards from toxic fumes, heat, noise or vibrations in the living
        quarters.
·       Unless the engine is protected by a cover or its own enclosure, exposed moving or hot parts of the engine
        that could cause personal injury shall be effectively shielded.
·       Engine parts and accessories that require frequent inspection and / or servicing must be readily accessible.
·       The insulating materials inside engine spaces shall be not combustible.

ENGINE MOUNTING
To ensure vibration free operation, the engine must be installed on substantial
beds, extending as far forward and aft as possible and well braced to form an
integral part of the hull.
The engine must be installed as low as possible on the flexible mount pillar stud.
This will limit vibration and extend the life of the flexible mount. If necessary, fit
spacer blocks below the mounts.
A flexible coupling should be fitted. Flexible couplings do not accommodate bad
alignment. The mating faces of the gearbox and tailshaft must be checked for
alignment, they must be parallel and concentric to within 0.005" (0.127mm).


ALIGNMENT
Alignment must be checked for parallel (A) and concentric (B) misalignment using
a set of feeler gauges.
To obtain accurate alignment the flexible mountings must be adjusted until
alignment is attained, and the mountings must be locked in position.
Once mounts are tightened, alignment must be re-checked. Coupling can now be
fitted in accordance with instructions supplied with coupling.


WARNING
(1) Do not set the engine feet high up the flexible mount pillar stud. This will cause
excessive engine movement and vibration. Pack under the flexible mount with
steel shims securely bolted into the engine bearer.
(2) The pillar stud on the flexible mount is secured into position by the lower
locknut, do not forget to tighten this. Also ensure that the stud is not screwed too far through the mounting
body so that it can touch the mounting bearer. This will cause vibration and knocking noises which are very
hard to find!




Exhausts
(a)        A correctly installed engine as described in this handbook will meet the exhaust emission requirements of
           Directive 2003/44/EC amending the Recreational Craft Directive 94/25/EC.

(b)        For compliance with exhaust emissions requirements, engines must have correctly installed exhaust
           systems. To ensure exhaust emissions are kept within permissible limits it is most important to reduce
           exhaust back pressure to a minimum, whilst ensuring exhaust is adequately muffled. Back pressure
           increases as exhaust length increases and from bends in the exhaust system. The exhaust back pressure,
           measured with the exhaust system connected and the engine running at full speed, must not exceed
           80mmHg (3.1inchesHg / 42 inches WG). The correct measuring point is at the position where the exhaust
           connects to the exhaust manifold. That is before the water injection elbow or dry exhaust bellows.


Wet Exhaust hose should be matched to the following injection bend sizes.

WARNING:

(1) One of the most common problems with engine installation is water entering the exhaust
    manifold from the exhaust system by syphoning. This can occur when the point of water
    injection (X) on the engine is close to or below the water line. Water entering the pistons
    can cause bent con rods, emulsified engine oil and a wrecked fuel pump! Its best
    avoided!

(2) The diagram shows a typical installation. It is essential that the small black rubber hose
    connecting the heat exchanger with the injection bend is removed and replaced by a
    hose marked `a'. This must be of sufficient length to supply either a T piece or an anti-
    syphon valve sited at least 300mm (12 inches) above the water line and on the centre
    line of the boat. The pipe then returns to the injection bend and the sea water is
    pumped down the exhaust pipe.

(3) The exhaust back pressure should not exceed 3.1 inches of Hg.




                                                      24
1. The mechanical fuel lift pump is fitted to all engines as standard, but if a suction head of 0.25m is
required then an electric fuel lift pump must be fitted (ask your dealer or Beta Marine).
2. It is very important that the excess fuel from the injectors is fed back to the fuel tank and not back to
any point on the supply line. This will help prevent air getting into the system.
3. Fuel pipe sizes are:               Supply (mm)                  Leak off (mm)
                                                8                           8
4. Any fuel leaks in the system are likely to cause poor starting and erratic running and must be
corrected immediately.
5. A fuel/water separator must be installed. (See 7).
6. The fuel return (leak off) pipe must loop down to be level with the bottom of the tank before it enters
the top of the tank - see 12. This prevents fuel `drain down'. This can cause poor starting. (See 12).
7. Fuel lines and hoses must be secured and separated or protected from any source of significant heat.
The filling, storage, venting and fuel supply arrangements and installations must be designed and
installed so as to minimise the risk of fire and explosion. Flexible fuel hoses connecting the engine to
fuel tank supply and return lines must meet the requirements set in standard ISO 7840:1995/A1:2000
and as required by your surveyor / authority.
SEAWATER INLET SYSTEM (Heat exchanger cooled engines)
Your engine is fitted with a gear driven sea water pump which sucks in seawater or raw water to cool the
closed circuit system via the heat exchanger.
1. It is very important that the seawater inlet should
have a strainer system either built into the sea cock or a
high level system with visual inspection glass, as
shown, mounted just above the water line.
2. The inlet sea cock and pipe work to the sea water
pump should be 25mm ID or 1" minimum.
3. Good access to the inlet sea cock is essential so that
plastic bags or seaweed trapped in the intake can be
poked out!
4. All pipe work should have approved marine grade
stainless steel hose clips. Any loose clamps or bad
connections can cause flooding and sinking the vessel.
5. If water is required for stern tube lubrication then this should be taken from a `T' piece in the pipe
going from the heat exchanger outlet to the water injection bend.
6. Scoop type water pickups should never be used, as water will be forced through the pump and into
the exhaust system whilst the vessel is in motion. This is very dangerous as the exhaust will eventually
fill and raw water will back up into the engine through the exhaust valve. Catastrophic failure will result
as soon as the engine is restarted.
Note: The maximum lift of the sea water pump is 2m




                                                      25
CALORIFIER SYSTEM
All Beta engines can be fitted with the engine tappings
to allow the hot water from the closed fresh
water/antifreeze system to circulate through a calorifier
tank, which in turn heats up domestic water.

Calorifier tappings on this range of engine are shown.

1. The big problem with a calorifier is to remove all the
air from the system. If this is not achieved then they
don't work!

2. Try and keep the supply and return pipes either
horizontal or sloping down in a continuous fall towards
the calorifier. This avoids air pockets being created.

3. Extra care must be taken when first filling the
calorifier circuit system with 50% antifreeze to water
solution as the engine may appear to be full but it soon
disappears into the calorifier pipe work. Run the engine
off load for 10 minutes then check the level as
described in `Filling The Fresh Water System'.
Also check to see if the pipe going to the calorifier is getting warm. Top up the water level as required
and run for another 10 minutes then repeat.
4. If the water level is steady but no warm water is getting to the calorifier then very carefully open the
calorifier bleed valve (see manufacturers instructions) or if none is provided then very carefully loosen
the jubilee clip securing the supply pipe to the calorifier. Air should escape. Refasten securely when no
further bubbles are seen.

CAUTION
Do not do this when the engine is hot as scalding hot water may be forced out of the pipe under
pressure.

ELECTRICAL INSTALLATIONS
Beta has 4 panel options: 2a
                          2ab'D' or 2ab'V' or 2ab'V'W
                          2b
                          & 2c'D'
The engine harness is common to all.
1. These panels must not be installed where sea water spray can get at them. A suitable flap or cover
must be fitted.
2. Panels must be fitted in a location where the helmsman can either see or hear the alarm system.
3. For standard wiring diagrams see following pages.
4. Extension looms longer than 3m (10 feet): As an option, Beta can provide various lengths of
extension looms for runs of over 3m, but this kit includes a start relay to overcome the voltage drop.
(See drawing 300-58520)
5. All electrical equipment must be protected from sea water. Sea water or rust in the starter will
invalidate warranty. Care must be taken when pushing the two halves of the plug together to ensure
that individual pins do not push out. To prevent corrosion and assist in assembly we recommend that
the plug is packed with petroleum jelly (Vaseline) and then carefully pushed together. The plastic boots
should cover both halves and overlap. A cable tie is then put round to hold the two halves in position
and help prevent any ingression of water.
6. All cables must be adequately clipped and protected from abrasion.
7. Electrical systems shall be designed and installed so as to ensure proper operation of the craft under
normal conditions of use and shall be such as to minimise risk of fire and electric shock.
8. Attention shall be paid to the provision of overload and short-circuit protection of all circuits, except
engine starting circuits, supplied from batteries.
9. Ventilation shall be provided to prevent the accumulation of gases, which might be emitted from
batteries. Batteries shall be firmly secured and protected from ingress of water

1. Keyswitch terminations
The standard panel keyswitch can be used to tap off a switched positive ignition feed to
power additional gauges. In this way these gauges will only be live whilst the engine is
running, the engine is starting or the heaters are being used.

For silver keyswitches, the terminal to achieve this ignition switched positive is marked `AC'.

For black keyswitches, the terminal to achieve this ignition switched positive is marked `15/54'.

For panels without any keyswitch, gauges can be driven from the 1mm2 brown wire, which
terminates at the 11 way connector terminal 4. This is a low power switched positive, any
additional power required from this connection must be fed through a relay, as noted below.

Note: these keyswitch terminals are rated at 10 amps maximum, since they are already
utilised for panel and alternator feeds Beta Marine recommends any additional
requirements from these terminals must be fed through a relay. This relay should then be
connected to it's own fused positive supply directly from the engine battery. Beta
drawing 202-06421 illustrating the wiring of a typical electric fuel lift pump with ignition
switched relay can be supplied upon request.

                           BETA CONTROLLER
                                SEA SPEC ENGINES
The BETA CONTROLLER is an integrated battery charging external regulator. It
is designed to be used with Beta s 70 and 100am p Iskra alternators.
The system utilises a three stage charging characteristic which optimises the rapid
charge of battery systems.
The first stage (A mode) is a boost charge, which is indicated by the indicator LED
showing red.
The second stage (B mode) is where the voltage is kept at a high level and where
the current is between 10% and 95% of the nominal alternator current, the LED
shows orange.
The third and last stage (C mode) is intended for maintenance of battery voltage
only. When the alternator current is under a predetermined value for a time greater
than 2 minutes, the regulating mode is changed from B to C mode.
The system automatically adjusts the charge mode to suit the load and is set in our
works for conventional lead-acid batteries. It can easily be re-set for deep cycle or
gel batteries. A more detailed specification can be obtained from BETA MARINE.

INSTALLATION

The Beta Controller has been designed
for mounting off the engine in a location
away from vibration, water and
condensation. Ideally as there is a
charge mode status LED, the unit should
be positioned to allow for inspection of
charge operating condition.
