will varyaccording to your crafts specific design It is not the intent of this section to advise boatyards or installerson procedures and wellunderstood However it is important that the there are details of the installation which require periodic checks to ensure the best operating conditions for the equipment and safe operating conditions for the personnel on board Proper location and installation of the diesel engine in the vessel are of prime in the installation that must be considered are ventilation to aid in cooling and to provide air for engine combustion exhaust system to properly discharge raw cooling water quiet the exhaust and expel exhaust gas cooling water supply fuel supply and electrical connections CAUTION For safety reasons the engine and transmission are NOT filled with lubricating oil for ship ment Before leaving the factory however each engine with transmission is thoroughly tested with oil in it This testing among other things provides all internal parts with a coating of 011 This oil acts as a preservative providing reliable protection against corrosion for at least one year if the engine and transmission are properly location should be such that it is dry and in an area where bilge water or water from above cannot splashon the engine The engine should be properly ventilated and accessible for minor servicing and repairs access for major repairs should be given consideration as well The location must be properly ventilated toprovide fresh air for engine combustion The engines lubrication oil sump dipstick the fresh water and oilfills and the transmissions dipstick and transmission or oil fill port must be accessible FILL CAoP COOLANT RECOVERY COCKPIT TANK ALTRNT MOUN11NO STRAP POSITIONS CABIN INSTALLATION ANGLE MUST HOT EXCEED l Please note that the engines installation angle cannot exceed 17 from the horizontal Diesel Engines 10Rigging and LiftingThe engine is fitted with lifting eyes Rope or chain slings capable of supporting the engines weight shouldbe attached to the eyes and the engine lifted by means of tackle attached to these slings The lifting eyeshave been designed to carry the full weight of the engine therefore auxiliary slings are not required or desired CAUTION Slings must not be so short as to place signaicant sheer stress on the engines lifting eyes Strain placed on the engines lifting eyes by the lifting sling must not be in excess of 10 from the vertical plain 10 SLXNG LIFTJNG ANGLE IoiUST NOT EXCEED 10 LIFTING EYE ENGINEThe general rule in moving engines is to see that all of the equipment used is amply strong and firmly fixedin place Move the engine a little at a time and see that tt is firmly supported Eliminate the possibility of accidents by avoiding haste Do not lift the engine by tts propeller coupling or pry against this coupling witha crowbar because excessive pressure of this type may distort the couplingIn certain situations it may be necessary to lift the engine in positions other than the horizontal position Certain situations exist by which the engine must be lowered endwise through a small hatchway which cannotbe made larger Under these conditions if the opening of the hatchway is extremely narrow tt is possibleto reduce to some extent the outside dimensions of the engine by removing external components such asthe alternator the cooling systems piping the heat exchanger certain filters the mounting lugs and equipment This accessory equipment should be removed by a competent mechanic and special care should be taken to avoid damaging any exposed parts In addition be careful not to allow dirt fromentering any opening created by the removal of equipment Parts removed should be returned to their respective position as soon as the engine has cleared the hatchwayIn case it becomes necessary to hoist the engine either frontend upwards or upwards theattachment of slings must be done carefully to avoid the possibility of damaging the parts on which the weightmay bear Special rigging work is best done by someone experienced and competent in handling heavymachinery 11 Westerbeke Diesel EnginesEngine BoltsBronze or stainless steel hanger bolts of appropriate size are recommended for use through the mounts Less preferred are lag screws because their hold on the Wood is weakened every time theyare moved whereas the hanger bolts stay in position If the nut on top of the hanger bolt is removed to allowthe engine to be lifted from s resting place the hanger bolt self remains in place as a stud Consequently the bond between the hanger bolt and the wood is not weakened by the removal of the nut or the for the EngineA good engine bed contributes much toward the satisfactory operation of the engine The engines bedmust be rigidly constructed and neither deflect nor twist when it is subjected to the engines weight or to thepressures that the boat may experience while operating in rough seas The bed must keep the within one or two thousandths of an inch of this position at all times The bed has to withstandthe forward push of the propeller shaft which pushes against the thrust washer bearing which finally pushesagainst the engines bolts and bedIn fiberglass hulls we recommend that similar wooden stringers as in wooden hulls be formed fitted andthen glassed securely to the hull This allows the hanger bolts to be installed firmly in the wood noise and transmitted vibrationThe engine support stringers must be as wide or wider than the engine mounting isolator Isolator overhangandor rounded stringer surfaces are detrimental to the isolators ability to retain fiberglass engine beds when used should be of sufficient thickness to properly support the engine and should be wellglassed to the hull temptation to Install the engine on a pair offiberglass angle Irons must be resisted will allow engine vibration to passthrough to the hull Flexible mounts require a firmfoundation against which they must act ifthey areto perform their function When possible followbed design A and avoid bed design B refer tothe illustration ASupports between the bed stringers and extending from the stringers to the hull may be requiredfor proper support and to aid in the absorption ofvibrations BAD B Note Avoid excessive height use solid stringer construction A Westerbeke Diesel Engines 12Propeller Shaft CouplingThe propeller shaft coupling fitted to the transmissions output flange must transmit not only the power of theengine to turn the propeller shaft and propeller but must also transmit the thrust of the ahead or asternThe coupling bore should be carefully machined for a slight forced fit onto the shaft and an accurate matingsurface for the coupling to the output flange of the W 40NA engine is equipped with a Federal Flexible Coupling The Federal Flexible Coupling consists ofa metal hub and a flange The hub Is accurately bored to accept the rubber bushings and the face of theflange Is machined to match the engines coupling The neoprene rubber bushings have a bonded innerbrass sleeve and the entire bushing is pressed into the flange using the correct compression pressure Alloysteel spider pins screw through the bushings into the hub which are locked into posttion The rubber bushings are ample to absorb vibration from the propeller and to allow a slight angular misalignment The is not designed to do the work of a universal joint The engine must be properly aligned before theFlexible Coupling is installed Afterthe coupling has been installed the coupling will compensate for misalign ments caused by hull distortion and from engine movement The Federal Flexible Coupling will absorb boththrust and torsional loads The pins and rubber bushings are replaceable in case of damageWhen ordering replacement parts refer to the Parts List at the back of this type and size of propeller varies with the gear ratio and must be selected to Itt the application basedupon boattests To utilize the full power olthe engine and to achieve ideal loading conditions use a propellerwhich will permit the engine to reach tts full rated RPM at full throttle while under a normal load and while itis moving the boat forward through the waterAlignment of the EngineThe engine must be exactly aligned with the propeller shaft using a solid coupling before installing the No matter what material is used to build a boat the material will be found to be flexible to some extent hence the boats hull will change its shape to a greater extent than is usually realized when the boat islaunched and operated in the water Therefore it becomes extremely important to check the engines alignment at frequent intervals and to correct any errors when they between the engine and the propeller shaft often creates serious problems which are oftenblamed on other areas suspected of causing the trouble Misalignment will cause excessive bearing wearrapid shaft wear and will in many cases reduce the life of the boats hull by loosening the hulls fasteningsA bent propeller shaft will have the exact effect as those just stated therefore a perfectly straight propellershaft is absolutely necessary One particularly annoying result of misalignment may be leakage of transmission oil through the transmissions rear oil sealNever attempt a final alignment with the boat on land The boat should be in the water and have had an opportunity to assume its final water form The best time to perform the propeller is with the fuel and water tanks about half full and all the usual equipment on board and after themain mast has been stepped and the final rigging has been accomplished 13 Westerbeke Diesel EnginesTake plenty of time in making this alignment and donot be satisfied wtth anything less than perfect resultsThe alignment is correct when the shaft can be easily 093 FEELER GAGEslipped backward and forward into the counterboreand when a feeler gauge indicates that the flangescome together at all points The alignment between PROPELLER SHAFTthe propeller shaft coupling and the engines couplingcan contain an error no greater than one thousandthof an inch per Inch of the coupling diameter For example if your propeller shaft coupling is three inchesin diameter the maximum error that can be allowed inthe alignment is three thousandths of an inch 003In making the final check for alignment theengines half coupling should be held in oneposition and the alignment with the tested wtth the propeller coupling ineach offour positions A while rotated 90 between each position This test will also checkwhether the propellers halfcoupling is in exactalignment on its shaft Then keeping thepropeller coupling in one position the alignment should be checked by rotating theengines halfcoupling in 90 increments checking dimension A while in each 90 position until the halfcoupling has been rotated full circle The engines alignment should be recheckedafter the boat has been in service for one tothree weeks and if necessary perform thealignment again Usually tt will be found thatthe engine is no longer in alignment This doesnot mean that the work has been done improperly at first rather tt means that the boathas taken some time to take its final shape andthat the engines bed and stringers haveprobably absorbed some moisture It may even be necessary to realign the coupling halves again at a later time Westerbeke Diesel Engines 14Exhaust SystemThe exhaust system provides an outlet line to vent engine exhaust gases out of and away from the vesselThe system also discharges sea water which has passed through the engines sea water circuit by mixing itwith hot exhaust gases This mixing helps cool the exhaust gases and exhaust elbow and plumbing The exhaust system and the sea water supply to the exhaust must be configured to prevent the siphoning of seawater into the exhaust through the sea water cooling circuit and to prevent the entry of sea water into the exhaust through the circutts throughhull discharge port If not prevented sea water entering through the discharge port can fill the exhaust system muffler and enter the engines cylinders This will prevent properstarting and possibly cause damage to internal engine componentsThe sea water supply hose to the exhaust system water injection elbow should be routed looped at least12 inches above the vessel water line An antisiphon break should be installed when needed at the top ofthis loop The top of the loop should be placed high enough above the vessels water line so as to remainabove the water line when the vessel is underway no matter what the angle of heel or roll may be 74 or 1 It LD hose NOTE The engines heat exchanger outlet will determme the Ik or 1 ff dimenSion lor the vented loop 48 max Installation with exhaust J elbow at a minimum of 6 above vessel water line HydrOHush Waterline Insulate 48 mal CAUTION Vented loop must be in a location where it will remain above the water line during all aHitudes of the vessels operation installation with exhaust HydroHush elbow at or below vessel water lineThe sea water supply throughhull sea cock fittings must be of the flushhull type Highspeed scoop typeof fittings should not be used as they tend to encourage siphoningThe exhaust discharge from the water lift muffler should be routed well above the water line then downwardto the throughhull discharge This routing will prevent sea water entry if the throughhull discharge fittingbecomes submerged when the vessel heels or rolls while under way or is subjected to following sea conditions Refer to the figures shown above for recommended exhaust system installations 15 Westerbeke Diesel EnginesExhaust exhaust discharge hose must be of adequate size andminimal run to prevent excessive exhaust backpressure should be checked before the engineis put into service Refer to the illustration Excessive backpressure will affect the engines performanceTo measure for backpressure use a mercury manometer apressure gauge or a water column A boatyard or marine should have a manometer or a pressure gauge ElbowMeasure backpressure at the exhaust elbow when the en gine is running at 3000 rpm Backpressure as measured by Exhausta manometer a pressure gauge or water column should not be over the following specifications I Mercury Manometer NOTE Other pressure gauges may be available to test for exhaust backpressure Check with a competent mechanicRefer to the pressure specifications belowA water column can be made by taking a clear plastic tubeand taping one end of the tube along a yardstick and fittingthe other end of the tube with a 14 inch NPT National PipeTap pipe fittingMeasure backpressure at the exhaust elbow when the engine is running at 3600 rpmDimension A cannot exceed 39 inches of waterBack pressure as measured by a gauge instrument shouldnot exceed the following specifications 3 inches of mercury 0104 kgcm 2 39 inches of water in a water column 099 kgcm2 at 4 C 22 ounces psi 1 12 psiExcessive backpressure can be caused by a small diameter exhaust hose a small muffler sharp bends inthe exhaust hose improper fittings water pockets and a high volume of water in the exhaust system dueto the length of the exhaust discharge hose The use of elbows and fittings in the exhaust discharge hosesrouting should be limited since these will create flow restrictions and contribute to exhaust engines exhaust system must be separate from any other engines exhaust system Dry portions of theexhaust system between the engines exhaust manifold and the water injected exhaust elbow must be insulated to hold in the heatWesterbeke Diesel Engines 16Exhaust System FailuresWhen the engines sea water is fed into an exhaust system so that the full stream of this water strikes a surface erosion takes place This erosion may cause premature failures The proper design of either a waterjacketed or water injected wet exhaust system to prevent this problem requires that the sea water inlet bepositioned so that the entering stream of sea water does not directly strike a surface In addition the velocityof the entering sea water stream should be as low as possible which can be achieved by having inlet fittingsas big in diameter as possibleThe best protection against exhaust system leaks is to routinely inspect the complete exhaust system Checkfor leaks around manifolds gaskets and welds Make sure exhaust lines are not heating surrounding If excessive heat is present correct the situation immediately If you notice a change in thesound or appearance of the exhaust system inspect the exhaust system and correct the causeExhaust risers installed off the exhaust mannold should not exceed 8 Ibs in total weight wen rigidly connected Excessive weight and vibration can result in a manifold failure andor the fracturing of the riser fromthe manifold at tts attachment Dry portions of the exhaust connected to the manifold which lay before thewater Injected exhaust system MUST be properly insulated to retain the exhaust heat wtthin the exhaustpipe iWARNINGI Although diesel engine exhaust gases are not as toxic as exhaust fumes from gasoline en gines carbon monoxide is present in diesel exhaust fumes in less concentration Carbon monoxide is a dangerous gas that can cause and is potentially lethal Some of the symptoms or signs of carbon monoxide inhalation or pOisoning are as follows a Dizziness a Vomiting a Intense Headache a Muscular Twitching a Weakness and Sleepiness a Throbbing in Temples If you experience any of the above symptoms get out into fresh air sure there are no unnecessary objects suspended from any portion of the exhaust lines could cause deflection or distortion of the lines resulting in damage or leaks Inspect insulated portions of the exhaust system to ensure there is no deterioration of the insulationOil Drain HoseAn oil sump drain hose is located at the lower front of the engine Oil may be drained from this hose byremoving the cap and the discharge end of the hose from the support bracket and lowering the hose into acontainer The hose cap fitting is 14 inch NPT National Pipe Tap and can be extended or have a pumpadded for easier removal of the old oil if desired 17 Westerbeke Diesel Pressure Sensing Devices to Oil GalleriesOil pressure sensing devices such as senders and switches must not be connected to an engines oil gallery with the use of extended nipples or tees The reason is simply that continued engine vibration causesfatigue of the fittings used to make such a connection If these fittings fail the engine loses its oil pressureand quickly seizesWhen additional sensing devices such as switches or sensors need to be installed that function on engineoil pressure these devices must be and connected to the oil gallery using an of lubricating oil hose Any fittings used to connect the hose to the gallery must be of steel or malleable iron composition Brass must not be used for this Alarm System High Water Temperature AlarmA high water temperature alarm buzzer has been supplied with the instrument panel If the engines freshwater coolant reaches 2100 F 988 C a water temperature switch on the engine closes causing the alarmto emit a continuous signal Refer to the DESCRIPTION OF INSTRUMENT PANEL section of this manualfor the location of the alarm in your engine panel page 24 Low Oil Pressure AlarmA low oil pressure alarm switch is located off the engines oil gallery This switch monitors the engines oilpressure Should the engines oil pressure fall to 10 15 psi the switch will close sounding this same alarmIn this event the alarm will emit a pulsating signal Refer to the DESCRIPTION OF INSTRUMENT PANELsection of this manual for the location of the alarm in your engine panel page 24Cooling SystemThe engine is fresh water cooled by an enginemounted heat exchanger Sea water is used as the heatexchangers cooling medium Sea water is pumped into the exchanger by a sea water pump where it coolsthe fresh water that circulates through the engine block and is then injected into the exhaust elbow carrying with it the heat removed from the engines fresh water cooling systemSea water should be supplied to the sea water pump through a flushtype hull fitting using a between the throughhull fitting and the sea water pump The sea water should be directed through avisualtype sea water strainer which will trap debris before it reaches the sea water pump and the heat exchanger and then be delivered to the pump Hoses routed from the throughhull fitting to the strainer andto the sea water pump should be wirereinforced to prevent the hose from collapsing while the engine is running suction from the pump may collapse a nonreinforced hose The sea water strainer should be mountedat or below the water line to make sure the sea water line remains Diesel Engines 18 CAUTION DO NOT use a scooptype throughhull fitting as a means of supplying sea water to the en gine Water pressure against this type of fitting while the vessel is under sail can push sea water past the sea water pumps impeller into the engines exhaust system filling it and the engine as well Flushtype clear throughhull fittings are recommended and should be lo cated on the hull so as to be below the waterline during all angles of boat operation The use of commontype street elbows is not recommended for plumbing the sea water cir cuit These generally have very restrictive inside diameters Machine fittings are preferred To Fresh Water Circulating Pump

that the throughhull inletsea cock and strainer are unobstructed Sea cocks and strainers should be at least one size greater thanthe inlet thread of the sea water pump The strainer should be of the type that may be withdrawn for cleaning while the vessel is at sea and should be mounted below the water line to ensure selfpriming Inspectthe sea water lines to ensure there are no collapsed sections which would restrict water flow Make surethere are no air leaks at any of the connections Placing double clamps at the sea water plumbing connection located below the water line is strongly SystemThe fuel system should be installed in such a manner as to allow the enginemounted mechanical fuel liftpump to maintain a positive inlet pressure to the fuel injection pump under all operating conditions Theminimum size of the fuel supply line and fuel return line is 14 inch inside diameter and there should be aprimary fuel filter installed between the fuel tank and the fuel lift pump Only one fuel filter is installed on theengine between the mechanical fuel lift pump and the injection pump this filter has a replaceable filter elementThe fuel tanks fuel pickup tube should be clear and unobstructed No screen or gauze strainers should beincorporated in the fuel pickup tubeMake sure that the fuel supply and return lines are securely anchored to prevent chafing and that all fillingsare sufficiently tightened to prevent leaking Also make sure your fuel system has a positive shutoff valveknow its location and how it operates NOTE DO NOT use springloaded check valves in the fuel supply line in lieu of mechanical shutoff valves This type of valve can create fuel starvation problems for the engines fuel sys temFuel tanks that are located below the engines fuel system level must have its fuel return at the tank extending down into the tank in the same manner as a pickup tube otherwise fuel siphoning out of the enginesfuel system through the return will take placeEnsure that the fuel tank filler is properly sealed to prevent water entry should tt become awash The fueltanks vent should be routed so as to prevent water entry as wellBe sure there is a fire extinguisher Installed near the unit and that it is properly maintained Be familiar withits use An extinguisher with the NFPA rating of ABC is appropriate for all applications in this environment Westerbeke Diesel Engines 20Electrical SystemThe electrical system should be checked to ensure that all wiring harnesses are tied down properly withclamps or plastic ties spaced at intervals close enough to prevent chafing from vibration Check to ensurethat all the engines harness connections are tight and that they are connected to the appropriate terminals WARNINGI Do not smoke or allow an open flame near batteries Lead acid batteries emit hydrogen a gas Turn off the emergency switch in the positive line of batteryMake sure the positive battery connection is connected to the battery connection of the starting solenoidThe negative battery connection should be connected to the system ground the engine block IWARNINGI When servicing the battery or checking the electrolyte level wear rubber gloves a rUbber

startEnsure that the Installation Checks have been made in accordance with those specified in the INSTALLATION CHECKS section of this manual refer to page 10Westerbeke Diesel Engines 22Starting SystemThe W 40NA diesel engine uses an electric starter for both normal and cold weather starting A cold start aidsystem is furnished on the W 40NA engine as standard equipment part 36258 Both the thermostart deviceand the cold start aid are located on the air intake manifold side of the engine The PREHEAT button energizes the thermostart device assists in vaporizing the fuel at the intake manifold inlet The vaporized dieselfuel is drawn into the cylinder during cranking and allows for easy combustion during compression Thisprocess allows the engine to start rapidly and reduces wear on the starter Air I ntake Screen Stand Pipe Thermostart Cold Start AidThe W 40NA engines electrical system is designed so that the PREHEAT button must be depressed for thetime specified in the Preheat chart shown on page 26 While keeping the PREHEAT button depressed theSTART button must be pressed to crank the engine NOTE The START button will not crank the engine unless the PREHEAT button is depressed atthe same time When the PREHEAT button is depressed the thermostart device is activated USE THE PREHEAT BUnON ONLY AS NECESSARY Overuse of the PREHEAT button will overheat the thermostart deviceRefer to the STARTING PROCEDURE section of this manual for starting instructions page 26 23 Westerbeke Diesel Engines STOPPING PROCEDURESIn the cockpit of the boat there Is a tee handle or a knobtype shutof control When this control is pulledOUTWARD the control will STOP the engine The other end of the shutoff control is attached to a lever onthe top of the fuel Injection pump Pushing the shutoff control fully inward will place the engine in the RESTART RUN positionWhen the engine is stopped turn the Circuit Breaker located in the vessel to the OFF position If the CircuitBreaker is left ON the battery will discharge CAUTION DO NOT attempt to shutdown the engine by turning the Circu Breaker OFF The Circuit Breaker only provides power to the instrument panel and to the DC alternator the engine will continue running even if the Circuit Breaker is turned OFF Stop the engine by pulling the shutoff control fully OUTWARDEngine BreakIn your engine has experienced a minimum of one hour of test operations to ensure accurate assembly and proper operation of all systems breakin time is required The service life of your engine is dependent upon how the engine is operated and serviced during s initial hours of useYour new engine requires approximately 50 hours of Inial conditioning operation to break In each movingpart in order to maximize the performance and service life of the engine Perform this conditioning carefully keeping in mind the following 1 Start the engine according to the STARTING PROCEDURE section found on page 26 run the engine at fast idle while checking that all systems sea water pump oil pressure battery charging are function ing 2 Allow the engine to warm up preferably by running at fast idle until the gauge moves into the t 30140 F range 3 While using the vessel under power vary the engines rpm cruise settings during the engines initial 25 hours of operation 4 Avoid rapid acceleration especially with a cold engine 5 Use caution not to overload the engine The presence of a gray or black exhaust and the inability of the engine to reach its full rated speed are signs of an overload that is a propeller that is too large 6 During the next 25 hours the engine may be operated at varying engine speeds with short runs at full rated rpm Avoid idling the engine for prolonged periods of timeBreakingin a new engine basically involves seating the piston rings to the cylinder walls This cannot be accomplished by long periods of running at Idle nor by early running at full speedIdle running may glaze the cylinder walls resulting in excessive oil consumption and smoky operation Excessive speed or heavy overloading especially with a cold engine may cause scoring of the cylinder wallsproducing similar Diesel Engines 28As indicated above operate the engine in moderation during the 50hour breakin period On one handdont baby the engine but on the other hand however dont abuse itStarting Under Normal the procedure below for normal starting of the engine 1 Check the engine and transmission lubricant levels and fill if necessary 2 Make sure there is sufficient fuel on board Keep fuel tanks as full as possible Check the fuel filters and water separators for the presence of contaminants andor water Drain and clean them as needed 3 Check the coolant level in the plastic recovery tank Add coolant solu1ion as needed NOTE Excessive loss of coolant from the plastic recovery tank indicates a cooling system leak Check the entire cooling system and the recovery tank and s connections at the ex haust manifold and pressurize the system to locate the leak In cases of excessive coolant loss the system must be refilled as outlined under the PREPARATION FOR STARTING sec tion of this manual page 22 4 Check for oil and fuel leaks particularly if signs of such leaks are found on the bottom of the engine or below the engine 5 When checking your engines coolant and oil levels check the engine for any noticeable

SystemThe W 40NA engine has only one replaceable fuel filter located on the enginemounted fuel system Thisfuel filter is located just after the discharge side of the mechanical fuel lift pump Gust below the fuel filterThe manualbleeding design of the fuel system allows the fuel filter to be easily serviced To replace the fuelfilter remove and replace filter elements as described in the Replacing Filter Elements section of thismanual page 35 Be careful to catch any fuel that may spill from within this fuel filter assembly NOTE Any primary fuel filterWater separator installed between the fuel tank and the engines fuel lift pump that is a Raycor Dahl or other similar filters should be manually filled before an attempt to bleed the fuel system between the fuel tank and the engine is madeTo bleed remaining air from that portion of the fuel system which runs between the fuel tank and the engineonce the primary fuel filter has been manually filled move the mechanical fuel lift pumps priming lever upand down using steady even strokes one stroke per second for a period of one minute For this no fittings should be open Refer to the illustration of the fuel system when following the procedure described above page 33 Fuel Supply IN Manual Priming Lever Mechanical Fuel Lift PumpRefer to the illustration on the next page when following the procedures described below1 After all air has been bled from between the fuel tank and the engine proceed to either one of the two bleed points 1 located on top of the fuel filter see the next page Choose the one that is easily asses sable Loosen the banjo bolt on top of the filter or the plug on the side of the filter housing one to two turns DO NOT remove the bolt or the plug2 Move the priming lever up and down as described on the previous page to purge the air out of the secon dary fuel filter through the open banjo bolt or plugWesterbeke Diesel Engines 32 NOTE As a safety precaution place a small plastic trash bag containing a few cloth rags around and under the secondary filterto catch any fuel that may spill from within the filter when it is removed Also note that when working the manual priming lever on the fuel lift pump move the lever up and down using long even strokes DO NOT operate the lever using rapid jerks In some rare instances the fuel lift pump may be at or near its internal maximum pump stroke In this situation no pumping action will be accomplished using the external manual priming lever In this case turn the engine over one or two turns do not attempt to start the engine to reposition the pumps internal pumping lever Now attempt to bleed the fuel system using the manual priming leverOnce the fuel system is bled which is indicated by a flow of bUbblefree fuel from bleed point 1 the banjo bolt or the plug and proceed to point 23 Using either a 516 box wrench or a 14 drive 516 socket wrench open the 516 2 bleed screw lo cated on the side of the fuel injection pump onehalf to one turn only DO NOT remove this special bleed screw Once again move the manual priming lever up and down to purge all of the air from this area of the fuel Injection pump When the fuel flows bubblefree from the 2

and bleed this portion of the fuel Injection pump in the same manner as described in step 3 Proceed to step 5 NOTE Make sure that the throttle Is fully open and the engines shutoff lever is in its RUN poslon before proceeding to step 55 Using a 58 open end wrench loosen all four high pressure injector line nuts 4 located at the base of each injector one to two turns Using the starter motor crank the engine over to bleed any air in the high pressure lines between the fuel Injection pump and the injectors Crank the engine until fuel spurts from between the injector nut and the high pressure injector line NOTE Only spurts of fuel should come from this bleed point not a steady flow of fuel DO NOT crank the engine for long periods of time Excessive cranking will cause the starter to overheat and will flood the exhaust system with sea waterRetighten ali four high pressure injector line nuts with the 58 open end wrench NOTE Excessive torque is not required to properly tighten the injector line nuts to the base of the high pressure injectors6 The engine is now primed and ready to start Leaving the throttle in the FULL OPEN posion make sure that the engines STOP lever is in the RUN posion and that the transmission is in NEUTRAL At this point proceed to start the engine Use the PREHEAT button as required and crank the engine using the starter Once the engine fires return then throttle to its IDLE position Check to make sure that the engines In struments indicate the proper oil pressure reading and that sea water is discharged with the exhaust Allow the engine to idle between 1000 to 1200 rpm for five minutes to make sure that all air in the fuel system has been bledIf the engine fails to start reprime the fuel system and try to start the engine once again CAUTION Prolonged cranking intervals without the engine starting can result in filling the engine mounted exhaust system with sea water coolant This may happen because the sea water pump is pumping sea water through the sea water cooling system during crank ing This sea water can enter the engines cylinders by way of the exhaust manifold once the exhaust system fills Prevent this from happening by closing the sea water supply throughhull shutoff drain the exhaust muffler and correct the cause for the excessive engine cranking needed to obtain a start Engine damage resulting from this type of sea water entry is not a warrantable issue the owneroperator should keep this in mind NOTE When the secondary onengine fuel filter has been serviced the 1 and 2 bleed points should only be bleed to make sure that ali air has been removed from the fuel system No other bleed points need to be opened at this time may find daubing white paint on each of the bleed points helpful If an un expected problem occurs in which the fuel system needs bleeding these points will be clear Diesel Engines 34While the likelihood of having to service the fuel system at sea is small the possibility does exist Thereforewe recommend that a replacement fuel filter be carried on board at all times Each fuel filter comes with twoOring gaskets Select the part numbers for this fuel filter from your Parts List and purchase spares from yourlocal Westerbeke Dealer or DistributorIf a leak should develop at a banjo or sealing washer that cannot be corrected by a simple tightening of thefitting replace the leaking washer A Fuel Hardware Kit is available for this engine which contains all the sealing washers used in the fuel system except those noted in the fuel filter replacement cartridge below Replacing the

time is required The service life of your engine is dependent upon how the engine is operated and serviced during its initial hours of useYour new engine requires approximately 50 hours of initial conditioning operation to break In each movingpart in order to maximize the performance and service life of the engine Perform this conditioning carefully keeping in mind the following 1 Start the engine according to the STARTING PROCEDURE section found on page 26 run the engine at fast idle while checking that all systems sea water pump oil pressure battery charging are function ing 2 Allow the engine to warm up preferably by running at fast idle until the water temperature gauge moves into the 130140 F range 3 While using the vessel under power vary the engines rpm cruise settings during the engines initial 25 hours of operation 4 Avoid rapid acceleration especially with a cold engine 5 Use caution not to overload the engine The presence of a gray or black exhaust and the inability of the engine to reach its full rated speed are signs of an overload that is a propeller that is too large 6 During the next 25 hours the engine may be operated at varying engine speeds with short runs at full rated rpm Avoid idling the engine for prolonged periods of timeBreakingin a new engine basically involves seating the piston rings to the cylinder walls This cannot be accomplished by long periods of running at Idle nor by early running at full speedIdle running may glaze the cylinder walls resulting in excessive oil consumption and smoky operation Excessive speed or heavy overloading especially with a cold engine may cause scoring of the cylinder wallsproducing similar Diesel Engines 28As indicated above operate the engine in moderation during the 50hour breakin period On one handdont baby the engine but on the other hand however dont abuse itStarting Under Normal the procedure below for normal starting of the engine 1 Check the engine and transmission lubricant levels and fill if necessary 2 Make sure there is sufficient fuel on board Keep fuel tanks as full as possible Check the fuel filters and water separators for the presence of contaminants andor water Drain and clean them as needed 3 Check the coolant level in the plastic recovery tank Add coolant solution as needed NOTE Excessive loss of coolant from the plastic recovery tank indicates a cooling system leak Check the entire cooling system and the recovery tank and its connections at the ex haust manifold and pressurize the system to locate the leak In cases of excessive coolant loss the system must be refilled as outlined under the PREPARATION FOR STARTING sec tion of this manual page 22 4 Check for all and fuel leaks particularly if signs of such leaks are found on the bottom of the engine or below the engine 5 When checking your engines coolant and all levels check the engine for any noticeable abnormalities such as loose or missing bolts loose brackets and mounts loose hose

the STARTING PROCEDURE section of this manual page 26 Westerbeke Diesel Engines 30Fresh water is pumped through the engine by a beltdriven fresh water circulating pump absorbing heat fromthe engine The fresh water coolant circulates through the engines block absorbing heat then passesthrough the thermostat into the exhaust manifold to the heat exchanger where it is cooled and then isreturned to the engine block through the suction side of the fresh water circulating pump When the engineis started cold external fresh water flow is prevented by the closed thermostat although some fresh waterflow Is bypassed around the thermostat to prevent the exhaust manifold from overheating As the enginewarms up the thermostat gradually opens allowing full flow of the engines fresh water coolant to flow unrestricted to the external portion of the cooling system A Fresh Water Coolant Antifreeze MixtureA freshwater and antifreeze mixture should be used yearround in the fresh water cooling system Waterwhen it freezes expands sufficiently to split the heat eXChanger and crack the engine block A mixture of proper concentration will prevent freezing see below for an mixture chartUse soft water with few Impurities such as tap water potable water or rainwater Never use hard or foulwater Use of hard water or water containing Impurities will lead to the collection of scale in the engine andheat exchanger which will reduce the cooling systems of poor quality or without rust inhibitors will cause corrosion within the COOling system Jwaysuse antifreeze which is compatible with aluminum cooling system components and is made by a Never mix different brands of antifreezeMake sure that the cooling system of the engine is well cleaned before adding antifreeze Recommended antifreeze for year round use is ZEREX or PRESTONE with rust inhibitorsIn order to control the concentration of the mixture mix the antifreeze and freshwater thoroughly before adding it to the cooling system

AFI specifications Into service grades CA CB CC and CD The use of CC or higher CD grades madeby wellknown manufacturers is recommended The oil selected should be used Oil Viscosity SAE NumberUse an oil having a viscosity best suited to the atmospheric temperature Use of an allseason oil SAE 10W30 with minimum viscosity change under different temperatures is suggested Atmospheric Temperature Viscosity 68 F 20 C or higher SAE 30 or 1OW3 41 F 5 C 68 F 20 C SAE 20 or 1OW3 41 F5 C or lower SAE 10W30 NOTE Do not usean engine lubricating oil with an SAE number greater than 30 in the engineOil PressureThe engines oil pressure during operation is indicated by the oil pressure gauge on the instrument panelsee page 24During normal operation the oil pressure will range between 30 and 60 psi At idle speed the oil pressurewill range between 20 and 35 psi At the time of cranking the oil pressure will rise with speed NOTE A newly started cold engine can have an oil pressure reading upwards of 60 psi A warmed engine can have an oil pressure reading as low as 35 psi These readings will vary depending upon the speed at which the engine is running 47 Westerbeke Diesel EnginesEngine Oil Change

THE HBW 150 HBW 150 transmission Is equipped with a helical gearing system The servooperated multlpledisc clutch requires only a minimum effort to change drives This featuremakes the transmission suitable for a singlelever remote control with a rod linkage such as a Morse or Bowden cable For safety reasons the transmission is NOT filled with transmission fluid for shipment Beforeleaving the factory however each transmission is thoroughly tested with fluid in the transmission This testing among other things provides all internal parts with a coating of transmission fluid This fluid acts as apreservative providing reliable protection against corrosion for at least one year if the transmission is proper1y stored DIPSTICK AND FIll HBW 150 transmission is an type Fill the transmission up to or near the top ofthe machined notch cut on the dipstick with approximately 060 US quarts 056 liters of automatic transmission fluid ATF The HBW 150 has its own dipstick and oil sumpChange the transmission fluid after the first 30 hours of engine operation and thereafter every 250 hours oronce per year minimum The HBW 150 transmission has a drain plug for draining the old transmission fluidTo ensure that most of the old fluid is drained from the transmission run the engine in NEUTRAL for approximately 10 to 15 minutes so the transmission fluid may warm and flow better from the transmission fluid may also be removed by inserting a small tube through the dipstick opening where fluid is added and attaching a pump onto the tube so the old fluid may be sucked out NOTE When removing the dipstick or drain plug make sure the thin aluminum sealing washer located under the plug is not lost Leakage will result if the sealing washer is not Diesel Engines 50 NOTE To check the transmission fluid level remove the dipstick and wipe off all transmission fluid on the dipstick and place the dipstick back in the hole where it was removed making sure that the base of the dipsticks threaded portion rests on the transmission housing Now remove the dipstick and see where the fluid measures on the dipstick If the transmissions fluid level lies below the notch add enough transmission fluid to raise the level back up to the notch Do not overtill the transmission DO NOT screw the dipstick into this hole to check the transmission fluid level Screw the dipstick into this hole only after an accurate reading of the fluids level has been taken Make sure that the dipstick is screwed in before and while the engine is operating Ensure that the sealing washer is present and that the dipstick Is not crossthreaded or overtightened TO CHECK OIL LEVEL TRANSMISSION IN OPERATION b FLUID LEVEL DAAINPLUGThe Transmission drain plug is located directly below the dipstick and is

their craft including engines and generators for layup duringthe offseason or for long periods of inactivity Others prefer to accomplish layup preparation themselvesThe procedures which follOW will allow you to perform your own layup and or to use asa check list others do the procedures should afford your engine protection during a layup and also help familiarize you with themaintenance needs of your engineIf you have any questions regarding layup procedures call your local servicing dealer he will be more thanwilling to provide CouplingThe transmission and propeller half couplings should always be opened up and the bolts removed wheneverthe boat Is hauled out of the water or moved from land to water and during storage in a cradle The flexibilityof the boat often puts a severe strain on the propeller shaft or coupling or both while the boat Is taken outor put in the water I n some cases the shaft has actually been bent by these strains This does not apply tosmall boats that are hauled out of the water when not in use unless they have been dry for a of timeFresh Water Cooling SystemA 5050 solution of antifreeze and fresh water is recommended for use in the fresh water cooling system atall times This solution may require a higher concentration of antifreeze depending on the areas winterclimate Check the solution to ensure that the antifreeze protection is adequateShould more antifreeze be needed drain an appropriate amount from the engine block and add a more concentrated mixture Operate the engine to ensure a complete circulation and mixture of the antifreeze concentration throughout the cooling system Now recheck the antifreeze solutions SystemWith the engine warm drain all the lubricating oil from the oil sump Remove and replace the oil filter Placesome paper towels and a plastic bag around the filter to catch the oil during its removalWhen installing the new oil filter be sure to apply a small amount of oil on the rubber sealing gasket at thebase of the filter Fill the sump with the correct amount of oil for your engine Refer to section of this manual page 8 Use an oil with an API specicatlon of CC or CD Runthe engine and check for proper oil pressure and ensure that there are no leaks 63 Westerbeke Diesel Engines CAUTION Do not leave the engines old lubricating oil in the sump over the layup period Lubricating oil and combustion deposits combine to produce harmful chemicals which can reduce the life of your engines internal partsFuel SystemTop off your fuel tanks with No2 diesel fuel Fuel additives should be added at this time to control algaeand condition the fuel Care should be taken that the additives used are compatible with the primary filterwater separator used in the system Change the element in your primary fuel filterWater separator if thefuel system contains one and clean the separator sediment bowlChange the fuel filter elements on the engine and bleed the fuel system as needed Start the engine andallow it to run for 5 10 minutes to ensure that no air is left In the fuel system Check for any leaks that mayhave been created in the fuel system during this servicing correcting them as neededSea Water

lubricating oil in the opening of the intake manifold to block the opening Do not shove the cloth out of sight If it is not visible at and an attempt is made tostart the engine you may need the assistance of a servicing dealer Make a note to remove the cloth priorto startup The throughhull exhaust part can be blocked in the same mannerStarter and cleaning of the starter drive pinion is advisable if access to the starter permits its easyremoval Ensure that the battery connections are shut off before attempting to remove the starter Take carein properly replacing any electrical connections removed from the Diesel Engines 64Cylinder LubricationIt is not necessary to remove the fuel injectors from the cylinder head to squirt light lubricating oil into thecylinders for the few months of normal layup However if you anticipate a longer layup period 12 monthsormore we recommended that this procedure be performed The light oil in the cylinders will prevent thepistons rings from sticking to the cylinder walls Make sure you have replacements for the injector and returnline sealing time provides a good opportunity to inspect your Westerbeke engine to see if external ITems such asdrive belts or coolant hoses need replacement Check your basic spares kit and order items not on handor replace those items used during the layup such as filters and zinc batteries are to be left on board during the layup period make sure they are fully charged and that theywill remain that way to prevent them from freezing If there exists any doubtthat the batteries will not remainfully charged or that they will be subjected to severe environmental condITions remove the batteries andstore them In a warmer more compatible of your Westerbeke engine after a seasonal layup generally follows the same procedures as those presented in the PREPARATIONS FOR STARTING section page 22 regarding preparationfor starting and normal starts However some of the layup procedures will need to be counteracted beforestarting the engine1 Remove the oilsoaked cloths from the intake manifold and from the throughhull exhaust port2 Remove the sea water pump cover and gasket and discard the old

I do not sell or share any user data or anything else for that matter. The only personal information I save is in the site log which has a line for each page view which includes the IP address your browser sends in the header as well as which page you requested. I use this to block hackers and other bad actors. I do not use this raw data to create profiles on users. I periodically delete the log files.
If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
