the cooler for leaks and corrosion Make certain the air vent is clear and when checking the fluid level look for signs of water contamination fluid will appear as strawberry Storage requires special care Follow these procedures o Drain the water from the transmission oil cooler and replace it with a proper mixture of antifreeze coolant NOTE This operation will usually occur when the engine raw water cooling system is properly winterized o Clean up the transmission and touchup unpainted areas use heat resistant painto Fill the transmission with Dextron III ATF fluid to prevent internal corrosion Extended storage only 12 months or moreo Loosen attaching hardware froin the transmission output flange and propeller shaft coupling flange before removing the boat from the water Separate the flanges and spray with lubricant o Inspect the gear shift cable linkage and attachments Look for corrosion of the end fittings cracks or cuts in the conduit and bending of the actuator rods Lubricate all moving parts NOTE ljthe transmission is to be storedfor a long time twelve months or moreit slwuld be topped offwith fluid to prevent internal corrosion Reduce the fluid level before putting tlze engine back into service OIL COOLERS The continued flow of raw water through the cooler will in time erode the inside of the cooler causing cross leaks to occur These internal cooler leaks will cause one of the following two problems 1 Transmission fluid will leak into the flow of raw water and be discharged overboard through the engine exhaust A loss of transmission fluid will cause tlze transmission to faiL 2 The raw water will leak into the transmission fluid caus255ing an increase in transmission fluid This contaminated fluid will appear as strawberry cream The transmission will eventually fail Either case requires an immediate response 1 Install a new oil cooler 2 Refill the transmission with DEXTRON III ATF WARRANTY NOTES Service manuals are available from your BORG WARNER dealer For assistance contact BORG WARiTER 200 Theodory Rice Blvd New Bedford MA 02745 Tel 5089794881 BORG WARNER is aware of the shock loads that can be placed on its gears as the result of mechanical propeller oper255ation or fully reversing of the propeller blades while shifting Therefore torque loads and directional changes should be made at low engine speeds If it is found that a failure was caused by a shock load any warranty claim will be denied A CAUTION Systemrelated noises or vibrations can occur at low engine speeds which can cause gear rattle resulting in damage to the engine andor transmission BORG WARNER is not responsible for total torsional vibration of this type If any problems occur with the transmission see TRANSMISSION in this manual If water has contaminated the fluid the transmission fluid needs to be cleaned out and replaced with fresh fluid It will take several fluid changes to get rid of the contamination Check your dipstick each time until it appears as pure fluid Change the transmission filter and clean out the fluid lines that connect to the cooler If the transmission fails to shift properly it will most likely need the attention of a qualified transmission service facility A transmission cooler may last ten years or more but in some circumstances depending on operating hours tropical waters maintenance etc it might only last half that time WESTERBEKE recommends having a spare cooler aboard Engines Generators 57 BORG WARNER VELVET DRIVE TRANSMISSION FORWARD NEUTRAl REVERSE TRANSMISSION ACTUATING LEVER POSITIONS DAILY OPERATION o Check the transmission fluid o Visually check the gear shift linkage and transmission o Start the engine in neutral Allow a few minutes at idle for the fluid to warm NOTE Too Iowan idle speed will produce a chattering noise from the transmission gear and damper plate In such cases the idle speed should be increased o Shift into gear A CAUTION Shifting gears above 1000 rpm can cause damage to the engine damper plate Pulling the throttle back to Idle when shifting gears will save wear on the transmission and the damper plate INSPECTION o Visually check for oil leaks at the hydraulic connections Check for wear on the hydraulic lines and replace if worn o Lubricate the detent ball and shift cable attachments Inspect the shift linkage o Inspect the transmission bolts retorque if necessary A CAUTION Clutch failure will occur if the shift lever does not fully engage the detent ball posItions CHANGING THE TRANSMISSION FLUID After the initial 50 hour change the transmission fluid should be changed at every 300 operating hours thereafter or at win255ter haulout However the fluid must be changed whenever it becomes contaminated changes color or smells rancid o Remove the oil filler cap and dipstick Remove the oil cooler return line and allow the oil to drain into a container o Reconnect the oil cooler return line o Use a suction pump to remove the transmission oil through the filler capdipstick hole o Clean off the transmission and properly dispose of the used fluid o Refill the transmission with DEXTRON III ATF The quantity will vary depending on the transmission model and the installation angle Fill through the dipstick hole D Check the dipstick for the proper fluid level Replace the oil filler cap and dipstick press the dipstick into place and tum clockwise until fingertighto Run the engine shutdown and recheck the fluid level A WARNING Never pullout the dipstick while the engIne is running Hot fluId will splash from the dipstick hole This could cause severe burns Oil Capacity Approximately 25 quarts 236 literswill fill most to the oilleveI fill mark on the dipstick Many variables have a direct relationship to the oil capacity Additional oil will be required to fill the oil cooler and the cooler lines The angle of installation will make a difference in the quantity of oil required to fill the transmission CERTAIN THE RUBBER

the transmission is not filled with transmission fluid during shipment and the selector lever is temporarily attached to the actuating shaft Before leaving the WESlERBEKE plant each transmission undergoes a test run with Dextron III ATF transmission fluid The residual fluid remaining in the transmission after draining acts as a preservative and provides protection against corrosion for at least one year if properly stored TRANSMISSION fLUID Check the transmission fluid level on the dipstick If the transmission has not been filled fill with Dextran III and continue to use this fluid During the first 25 hours of operation keep a lookout for any leakage at the bell housing output shaft and transmission cooler This fluid should be changed after the first 25 hours and approximately every 300 operating hours thereafter andlor at winter layup A CAUTION Bs CBrtain the transmission Is filled and the correct size cooler is properly instaled before starting the engine SHIFT LEVER POSITION The gear shift control mechanism and linkage must position the actuating lever on the transmission exactly in Forward FNeutral Nand Reverse Rshifting positions A deteball located behind the transmission lever must work freely to center the lever in each position The gear shift positions at the helm must be coordinated with those of the Velvet Drive actuating lever through shift mechanism adjustments An improperly adjusted shift mechanism can cause damage to the transmission The shifting mechanism and transmission actuating lever should be free of dirt and well lubricated to ensure proper operation Shifting Into Gear Place the gear shift in Neutral before starting the engine Shifting from one selector position to another selector posi255tion may be made at any time below 1000 rpm and in any order Shifts should be made at the lowest practical engine speed Start the engine and set the throttle at idle speed allow the transmission fluid to warm up for a few minutes Neutral Move the gear shift lever to the middle position You should feel the detent This centers the actuating lever on the With the control in this position hydraulic power is completely interrupted and the output shaft of the does not turn NOTE Some transmissions are equipped with a neutral safety switch Unless the transmission actuating lever is perfectly aligned in neutral the engine starter will not activate Forward Move the gear shift lever to the forward position You should feel the detent The actuating lever267 on the transmission is in the forward position The output shaft and the propeller shaft move the boat in a forward direction Reverse Move the gear shift lever to the reverse position You should feel the detent The actuating lever on the transmission is in the reverse position The output shaft and the propeller should move the boat in a reverse direction asternNOTE Moving the transmission actuating lever from Neutral Position to Forward is always toward the engine Reverse is always away from the engine If boat moves backwards with the gear shift control in the forward position shut off the engine This problem may be a result of incorrect movement of the actuating lever by the gear shift lever WESIERBEKE I Engines Generators 55 ZF MARINE TRANSMISSIONS OPERATING TEMPERATURE A CAUTION If the transmission fluid temperature is too high stop the engine immediately and check the transmission fluid Norn1al operating temperature of the transmission fluid should be in the range of 1220 F 500 Cto 2120 F 1000 C A maximum temperature of 2660 F 1300 Cmay only reached for a short time Make certain there is enough space around the transmission to provide good ventilation and cooling TRANSMISSION COOLER Coolers are standard equipment for the ZF 10M ZF 12M ZF 15M ZF 15MA ZF 15MIV and the ZF 25M The cooler is a separate part of the transmission which prevents any possibilities of coolant diluting the transmission fluid However the continued flow of coolant thru the cooler will

housing output shaft and transmission cooler for leakage The fluid should be changed after the first 25 hours and every 300 hours thereafter NEUTRAL SWITCH These transmissions are equipped with a neutral safety switch This is to prevent the engine from starting in gear Unless the transmission selector lever is perfectly aligned in neutral the engine starter will not activate INITIAL OPERATION Set the shifting lever to neutral position NStart the engine and let it run long enough in idle to fill the cooler and hoses with transmission fluid Shift into gear forward and reverse shifting should be smooth and positive Direct changes from forward to reverse are permissible since the multiple disc clutch permits changing at high rpm including sudden reversing at high speeds in the event of danger After initial operation make a visuaI inspection of the output coupling oil cooler and hoses and the cable connections to the transmission LOCKING THE PROPELLER Locking of the propellyr shaft by an additional brake is not required use the gear shift lever position opposite your direction of travel for this purpose Never put the gear shift in the position corresponding to the direction of travel of the boat WHEN UNDER SAIL OR BEING TOWED Rotation of the propeller without a load such as when the boat is being sailed being towed or anchored in a river as well as operation of the engine with the propeller stopped for charging the batterywill have no detrimental effects on the transmission NOTE When the boat is being sailed engine stoppedthe gear shift must be in the neutral position The propeller is at idle and can freewheel DAILY OPERATION o Check the transmission fluid Visually check the gear shift linkage and transmission Start the engine in neutral allowing a few minutes at idle to warm the fluid D Shift into gear NOTE Too Iowan idle speed will produce a chattering noise from the transmission gear and damper plate In such cases the idle speed should be increased

MARINE TRANSMISSIONS DESCRIPTION The information below is specific to the ZF Transmissions the TRANSMISSION SECTION applies to aU models CONNECTION OF GEAR BOX WITH PROPELLER HEW recommend a flexible connection between the transmission gearbox and the propeller shaft if the engine is flexibly mounted in order to compensate for angular deflections The installation of a special propeller thrust bearing is not required since the propeller thrust will be taken by the transmission bearing provided the value specified under SPECIFICATIONS is not exceeded However the output shaft should be protected from additional loads Special care should be taken to prevent torsional vibration When using a universal joint shaft make certain to observe the manufacturers instructions Even with the engine solidly mounted the use of flexible coupling or DRIVESAVER will reduce stress in the gearbox bearings caused by hull distortions especially in wooden boats or where the distance between transmission output flange and stem gland is less than about 800mm ZF 15M A CAUTION The position of the mechanism behind the actll6ting lever is to ensure equal shift lever travel from neutral position A and B If this mechanism is in any way tampered with the transmission warranty will be void DID v is a product of Globe Marine Rockland MA NOTE When installing the transmission make certain that shifting is not impeded by restricted movability of the Bowden cable or rod linkage by unsuitably positioned guide sheaves too small a bending radius etc In order to mount a support for shift control cable connections use the two threaded holes located above the shift cover on top of the gear housing Refer to the WESTERBEKE parts list CONTROL CABLES The transmission is suitable for single lever remote control Upon loosening the retaining screw the actuating lever can be moved to any position required for the control elements cable or rod linkageMake certain that the shift lever does not contact the actuating lever cover plate the minimum distance between lever and cover should be O5mm The control cable or rod should be arranged at right angle to the actuating shift lever when in the neutral position The neutral position of the operating lever on the control console should coincide with the neutral position of this lever The shifting travel as measured at the pivot point of the actuating lever between the neutral position and end positions A and B should be at least 35mm for the outer and 30mm for the inner pivot point A greater amount of shift lever travel is in no way detrimental and is recommended However if the lever travel is shorter proper clutch engagement might be impeded which in tum would mean premature wear excessive heat generation and clutch plate failure This would be indicated by slow clutch engagement or no engagement at all NOTE Checkfor proper lever travel at least each season CONTROL CABLE NEUTRAL SHIFT LEVER N I COVER O5rnrn J MINIMUM

infomtation below is provided to assist the mechanic DESCRIPTION The lubricating system is a pressure feeding system using an oil pump The engine oil is drawn from the oil sump by the oil pump which drives the oil under pressure through the oil filter and various lubricating points in the engine The oil then returns to the oil sump to repeat the continuous cycle When the oil pressurc exceeds the specified pressure the oil pushes open the relief valve in the oil pump and returns to the oil sump keeping the oil pressure within its specified range TESTING OIL PRESSURE To test the oil pressure remove the oil pressure sender then install a mechanical oil pressure gauge in its place After warming up the engine set the engine speed at 1800 rpm and read the oil pressure gauge Oil Pressure Between 55 and 75 psi at 1800 rpm Note A newly started coldengine may have an oil pressure up to 70 or 80 psi A warmed engine can have an oil pressure as low as 40 psi Oil pressure will vary depending on the load placed on the generator OIL PRESSURE The engines oil pressure during operation is indicated by the oil pressure gauge on the ins1n1ment panel During normal operation the oil pressure will range between 40 and 85 psi NOTE A newly started cold engine can have an oil pressure reading up to 85 psi A warmed engine can have an oil pressure reading as low as 25 psi These readings win vary depending upon the temperature of the engine and the pms Low OH Pressure The specified safe minimum oil pressure is 5 10 psi A gradual loss of oil pressure usually indicates worn bearings For additional information on low oil pressure readings see the ENGINE chart Testing Oil Pressure To test oil pressure remove the oil pressure sender then install a mechanical oil pressure gauge in its place After warming up the engine set the engine speed at idle and read the oil pressure gauge MECHANICAL OIL PRESSURE GAUGE OIL PRESSURE SWITCH TYPICAL ARRANGEMENT Engines Generators 44 charging

ENGINE IDLING SPEED The engine idling speed is preset at the factory but once the boat is operating in the water other variables such as pro255peller size shaft length and the transmission can affect the idle speed The normal idle speed for these engines is 650950 RPM however simply put the idle speed should feel comfortable It should be quiet and smooth not racing but not so low that it causes transmission damper plate chatter SETTING THE IDLING SPEED To adjust the engine idle speed engine runningloosen the locknut of the idle adjustment bolt and tum the bolt clockwise to increase idle speed and to reduce Once the speed is set to your satisfaction tighten the locknut FUEL INJECTION PUMP TOPENGINE COMPRESSION Check the compression pressure To do this warm the engine remove all fuel

terminal R on the alternator and the negative probe to the ground terminal E on the alternator 2 Turn the ignition switch to the on position and note the multimeter reading The reading should be 13 to 25 volts see illustration3 If the reading is between 75 and 11 volts the rotor field circuit probably is shorted or grounded 4 If the reading is between 60 and 70 volts the rotor field circuit probably is open 5 If no reading is obtained an open exists in the lead or in the excitation circuit of the regulator Disconnect the lead from exe terminal R Connect the positive multimeter probe to the excitation lead and the negative multimeter probe to ground terminal E If the multimeter now indicates an approximate battery voltage the voltage regulator is defective and must be replaced If no voltage is indicated check the excitation circuit for loose or dirty connections or damaged wiring CHECKING THE SERVICE BATTERY Check the voltage of the service battery This battery should have a voltage between 13 and 14 volts when the engine is running If not there is a problem in the service battery charging circuit Troubleshoot the service battery charging circuit by checking the wiring and connections the solenoid isolator battery switch and the battery itself When the problem has been solved and before the alternator is back in operation take the time to tighten and clean the terminal studs Also clean the connecting tenninals from the wiring harness ALTERNATOR REPAIR If tests indicate a failed alternator it will need to be disassembled and repaired Any good alternator service shop can do the job NOTE WESTERBEKES Service Manual has detailed instructions for the disassembly and repair of their standard altemators BATTERY CARE The minimum recommended capacity of the

WIRING DIAGRAM FOR WIRE CONNECTIONS TO OPTIONAL ALTERNATORS 50AMP ALTERNATOR EXCITER TERMINAL l NOTE FOR CORRECT WIRING HARNESS CONNECTIONS TO THE ALTERNATOR REFER TO THE WIRING DIAGRAMS IN THIS MANUAL DESCRIPTION The following infonnation applies to the standard alternators that are supplied with WESTERBEKES Marine Engines and Marine Generators ELECTRICAL CHARGING CIRCUIT The charging system consists of an alternator with a voltage regulator an engine DC wiring harness a DC circuit breaker and a battery with connecting cable and wires Because of the use of integrated circuits Iesthe electronic voltage regulator is very compact and is mounted internally or on the back of the alternator It is desirable to test the charging system alternator and voltage regulatorin the boat using the wiring harness and electrical loads that are a pennanent part of the system Inboat testing will then provide the technician with an operational test of the charging system as well as the major components of the electrical system ALTERNATOR DESCRIPTION The stator is connected to a threephase fullwave bridge rectifier package which contains six diodes The bridge converts the AC generated in the stator to a DC output for battery charging and accessories such as a radio heater lights refrigerator depth sounder etc Power to the regulator and the field of the integral regulator alternator is provided by the field diode or diode triopackage contained in the alternator These alternators produce a rated output of 50 or 51 amps Rated output is achieved at approximately 6000 alternator rpm at an ambient temperature of75260F 238260CThe alternators are designed to operate in an ambient temperature range of 40260 to 212260F 400 to 100260CVOLTAGE REGULATOR The integral voltage regulator is an electronic switching device which senses the system voltage level and switches the voltage applied to the field in order to maintain a proper system voltage The regulator design utilizes allsilicon semi conductors and thickfilm assembly techniques After the voltage has been adjusted to the proper regulating value the entire circuit is encapsulated to protect the circuit and the components from possible damage due to handling or vibration and moisture encountered in a vessel ALTERNATOR Use this section to determine if a problem exists with the charging circuit or with the alternator If it is determined that the alternator or voltage regulator is faulty have a qualified technician check it LOW BATTERYFAULTY CIRCUIT If the starter only moans or makes a clicking sound instead of spinning the engine to life it is likely a low battery or a faulty connection in the starting circuit and not an alternator problem A simple test is to try starting again with a cabin light on if the light dims significantly or goes out the battery is dead If the light remains bright look for a poor connection in the starting circuit A WARNING A working alternator runs hot i a failed alternator can become very hot Do not touch the alternator until it has cooled fIVIWESTERBEKE I Engines Generators 34 the positive AdobeUCSwire to the alternator pulley If voltage is present you should feel the magnetic

engine in case the engine startsup Also warn other crew members of the danger POSITIVE TERMINAL IGNITION TERMINAL Test again by jumping the two large terminal studs Hold the screwdriver blade finnly between the studs Do not allow the screwdriver blade to touch the solenoid or starter casing this would cause a short A WARNING There will be arching as the full starting current should be flowing thru the blade of the screwdriver If the starter spins the solenoid is faulty If the starter fails to spin the motor is probably faulty If no arching occurred there is no juice reaching the solenoid NOTE Starter motors are either inertia type or preengaged In the preengaged model the solenoid also moves an arm that engages the starter motor to the flywheel of the engine using a screwdriver to bypass the solenoid on such a starter will run the motor without engaging the flywheel Tum the starter switch on to provide power to the solenoid Hopefully it will create enough magnetic field for the arm to move even though the contacts inside the solenoid are bad EMERGENCY START Corrosion to the starter brushes andor the solenoid contacts can cause the sporadic problem of the engine starting one time but not another If corrosion is the problem the starter will need to be rebuilt It is however sometimes possible to get started by taping the starter lightly with a small hammer With the battery switch off and no ignition tap lightly on the casing as shown then try to start the engine CAREFULLY NOT TO HIT FITTINGS OR WIRE CONNECTioNS I TAP LIGHTLY WHERE INDICATED If that fails tum the battery switch on and have a crew member tum the ignition on and off rapidly as you tap again with the hammer This may loosen the brushes and allow contact to start the engine When you reach a repair facility the starter will need to be repaired SERVICE WESTERBEKE uses a standard starter motor which can be serviced or rebuilt at any starter motor automotive service center If replacing the starter motor make certain the new motor is certified for marine use Automotive starters do not meet USCG standards If in doubt contact your WESTERBEKE dealer TO REMOVE FOR SERVICE 1 Disconnect the negative battery cable 2 If necessary remove any components to gain full access to the starter motor 3 Label and disconnect the wiring from the starter Do not allow wires to touch tape over the terminals4 Remove the starter mounting bolts 5 Remove the starter from the engine In some cases the starter will have to be turned to a different angle to clear obstructions En Jines Generators 3D AdobeUCSthe solenoid

water pump is a selfpriming rotary pump with a nonferrous housing and a Neoprene impeller The impeller has flexible blades which wipe against a curved cam plate within the impeller housing producing the pumping action On no account should this pump be run dry There should always be a spare impeller and impeller cover gasket aboard an impeller kitRaw water pump impeller failures occur when lubricant raw wateris not present during engine operation Such failures are not warrantable and operators are cautioned to make sure raw water flow is present at start255up The raw water pump should be inspected periodically for brokeno tom impeller blades See MAINTENANCE SCHEDULE NOTE Should a failure occur with the pump s iliternal parts seals and bearingsit may be more cost efficient to purchase a new pump and rebuild the original pump as a spare AIR INTAKE NOTE To operate efficiently a diesel engine must intake a continuous volume of clear air Hard starting an erratic idle and black

RAW WATER STRAINER OWNER RAW WATER SEACOCK INSPfCTAND CLEAN EVERY 100 HOURS Engines Generators 16 SYSTEM FRESH WATER COOLING CIRCUIT NOTE Refer to the ENGINE COOLANT page for the recommended antifreeze and water mixture to be used as the fresh water coolant Fresh water coolant is pumped through the engine by a circulating pump absorbing heat from the engine The coolant then passes through the thermostat into the manifold to the heat exchanger where it is cooled and returned to the engine block via the suction side of the circulating pump When the engine is started cold external coolant flow is prevented by the closed thermostat although some coolant flow is bypassed around the thermostat to prevent the exhaust manifold from overheatingAs the engine warms up the thermostat gradually opens allowing full flow of the engines coolant to flow unrestricted to the external portion of the cooling system Coolant Recovery Tank A coolant recovery tank allows for engine Coolant expansion and contraction during engine any significant loss of coolant and without introducing air into the cooling system This tank should be located at or above the engine manifold level and should be easily accessible COOLANT RECOVERY TANK NOTE PeriodicaUy check the condition of the manifold pressure cap Ensure that the upper and lower rubber seals are in good condition and check that the vacuum valve opens and closes tightly Carry a spare cap SEAL CHECKING THE PRESSURE CAP CHANGING COOLANT The engines coolant must be changed according to the MAINTENANCE SCHEDULE If the coolant is allowed to become contaminated it can lead to ovetbeating problems A CAUTION Proper cooling system maintenance is triflcal a substantial number of engine failures can be traced back to cooling system corrosion Drain the engine coolant by removing the drain plug on the engine block and opening the manifold pressure cap Flush tQe system with fresh water then reinstall the drain and start the refill process Refer to

walls are scored which is caused by overloading the engine during the breakin period Your new engine requires approximately 50 hours of initial conditioning operation to break in each moving part in order to maximize the performance and service life of the engine Perfonn this conditioning carefully keeping in mind the fol255lowing 1 Start the engine according to the STARTING PROCE255DURE section Run the engine at fast idle while checking that all systems raw water pump oil pressure battery chargingare functioning 2 Allow the engine to wann up preferably by running at fast idleuntil the water temperature gauge moves into the 130 140260F 55 60260Crange 3 While using the vessel run the engine at various engine speeds for the first 25 hours Avoid prolonged periods of idling 4 Avoid rapid acceleration especially with a cold engine 5 Use caution not to overload the engine The presence of a grey or black exhaust and the inability of the engine to reach its full rated speed are signs of an overload 6 During the next 25 hours the engine may be operated at varying engine speeds with short runs at full rated rpm Avoid prolonged idling during this breakin period CHECK LIST D Monitor the control panel gauges D Check for leaks of fuel and engine oil D Check for abnormal noise such as knocking friction vibration and blowback sounds D Confinn exhaust smoke When the engine is cold white smoke When the engine is warm almost smokeless When the engine is overloaded some black smoke and soot NOTE See the TRANSMISSION section of this manual for breakin information on your transmission Engines G200merators 10 STARTING STOPPING PROCEDURE CHECKLIST Follow this check list each day before starting your engine D Visually inspect the engine for fuel oil or water leaks D Check the engine oil level dipstickD Check the coolant level in coolant recovery tank Periodically check the manifold coolant leveL D Check the transmission fluid level D Check your fuel supply D Look for clean fuel in the fuel filterwater separator transparent bowL Check for loose wires at the alternator and make sure its mounting is secure D Check the starting batteries weeklyD Check drive belts for wear and proper tension weeklyD Visually inspect the raw water pump for leakage STARTING THE ENGINE 1 Place the transmission in neutral throttle advanced NOTE Hydraulically operated transmissions have a neutral safety switch through which the starter solenoid energizing circuit passes This switch is open when the transmission is in gear so the starter solenoid will not energize 2 Tum the KEY SWITCH to the ON position 2 oclockIf the panel is energized gauges are litand the alarm buzzer will pulse 3 Press the PREHEAT BUTfON and hold for 5 to 15 seconds depending how cold it is The foellift pump is priming the engine and the preheat is activated4 Continue pressing the PREHEAT BUTTON and press the START BUTTON The starter motor is cranking the engine5 Release the START and PREHEAT BUTTON as the engine starts The alarm buzzer should silence as the oil pressure rises 6 With the engine running check the instruments for proper oil pressure and battery charging voltage Also check for overboard discharge of exhaust water The water temperature will rise slowly until the thermostat opens Do not engage the gear shift until the temperature is close to nonnal NOTE Never attempt to engage the starter while the engine is ntnning It is important to closely monitor the panel gauges Become aware of the normal engine readings and take immediate action if these readings start to vary If a smart regulator is part of the charging system allow about 50 for the RPM gauge to activate FAILURE TO START If the engine fails to start when the start button is pressed for 5 seconds wait for at least 30 seconds and repeat the starting procedure Make certain the transmission control is in neutral position as some engines have a neutral safety SWItch to prevent starting in gear Never run the starter for more then 30 seconds If the engine fails to start refer to the CHART in this manual A CAUTION Prolonged cranking intervals without the engine starting can result in the engine exhaust system filling with raw water This may happen because the pump is pumping raw water through the raw water cooling system during cranking This raw water can enter the engines cylinders by way of the exhaust manifold once the exhaust system tills Prevent this from happening by clOSing the raw water supply throughhull shutoff draining the exhaust muffler and correcting the cause of the excessive engine cranking Engine damage resulting from raw water entry is not a warrantable issue the owneroperator should keep this in mind STOPPING PROCEDURE To stop the engine bring the throttle to an idle position and place the transmission in neutral Allow the engine to idle for a few moments to stabilize temperatures then shut the engine down by turning off the key switch NOTE When starting A voltage drop will occur when the preheat button is depressed Engines Generators 9 FOR INITIAL STARTUP Before starting your engine for the first time or after a prolonged layoff check the following items o Check the engine oil level Add oil to maintain the level at the high mark on the dipstick o Turn on the fuel supply then check the fuel supply and examine the fuel filterwater separator bowl for contaminants o Check the transmission fluid level o Check the DC electrical system Inspect wire connections and battery cable connections Make certain the positive battery cable is connected to the starter solenoid and the negative cable is connected to the engine ground stud this location is taggedo Check the coolant level in both the plastic recovery tank and at the manifold NOTE If the engine has not yet been filled with coolant refer to the COOliNG SYSTEM section of this manual D Visually examine the engine Look for loose or missing parts disconnected wires and unattached hoses Check the threaded connections and engine attachments D Make certain there is proper ventilation around the engine An ample supply is necessary for proper engine performance D Make sure the mounting installation is secure D Ensure the propeller shaft is securely attached to the transmission D Open the thruhull and make certain raw water is primed to the raw water strainer SIDE OIL FILL

ASTMand has a cetane rating of 45 or better Care Of The Fuel Supply Use only clean diesel fuel The clearance of1he components in your fuel injection pump is very critical invisible dirt particles which might pass through 1he filter can damage these finely finished parts It is important to buy clean fuel and keep it clean The best fuel can be rendered unsatisfactory by careless handling or improper storage facilities To assure that the fuel going into the tank for your engines daily use is clean and pure the following practice is advisable Purchase a wellknown brand of fuel Install and regularly service a good visualtype fuel filterwater separator between the fuel tank and the engine The Raycor 500 FG or 900 FG are good examples of such filters ENGINE OIL Use a heavy duty engine oil with an API classification of Cf or CG4 or better Change the engine oil after an initial 50 hours of breakin operation and every 100 hours of operation 1hereafter For recommended oil use sAE 15W40 oil viscosityand stay with 1he same brand of oil thruout the life of the engine A CAUTION Do not allow two Dr mDre brands of engine oil to mix Each brand contains its own additives additives of different brands could reacl in the mixture to produce properties harmful tD your engine ENGINE COOLANT WESTERBEKE recommends a mixture of 50 antifreeze and 50 distilled water Distilled water is free from the chemicals that can corrode internal surfaces The antifreeze performs double duty It allows the engine to run at proper temperatures by transferring heat away from the engine to the coolant and lubricates and protects the cooling circuit from rust and corrosion Look for a good quality antifreeze 1hat contains Supplemental Cooling Additives SCAsthat keep the antifreeze chemically balanced crucial to long term protection The distilled water and antifreeze should be premixed before being poured into the cooling circuit NOTE Lookfor the new long lasting antifreeze that is now available PURCHASING ANTIFREEZE Rather than preparing the mixture WESTERBEKE recommends buying the premixed antifreeze so that so that when adding coolant the mixture will always be correct There are two common types of antifreeze Ethylene Glycol greenand Propylene Glycol can be used but do not mix the two and if changing from one to another flush the engine thoroughly Premixed antifreeze for DIESEL Engines Specification ASTM 5345 MAINTENANCE Change the engine coolant every five years regardless of the number of operating hours as the chemical additives that protect and lubricate the engine have a limited life COOLANT RECOVERY TANK A coolant recovery tank kit is supplied with each generator The purpose of this recovery tank is to allow for engine coolant expansion and contraction during engine operation without the loss of coolant and without introducing air into the cooling system II Engines Generators 7 CONTROL PANEL DESCRIPTION This control panel is equipped with a KEY switch an RPM
