the gasoline engine since the mechanism is essentially the same Thecylinders are arranged above a closed crankcase the crankshaft is of the same general type as that of agasoline engine and the diesel engine has the same type of valves camshaft pistons connecting rods andlubricating to a great extent a diesel engine requires the same preventive maintenance as a gasoline engineThe most important factors are proper ventilation and proper maintenance of the fuel lubricating and cooling systems Replacement of fuel and lubricating filter elements at the time periods specified is a must andfrequent checking for contamination that is water sediment or algae in the fuel system is also important factor is the use of the same brand of high detergent diesel lubricating oil designed specifically for diesel engines Be careful not to put gasoline in the diesel fuel tanks Gasoline does not have thesame lubricating qualities as diesel fuel consequently gasoline in the fuel lines will damage components inthe fuel lift pump assembly fuel injection pump and injectorsThe diesel engine does differ from the gasoline engine however in its handling and firing of fuel The carburetor and ignition systems are done away with and in their place are two components the fuel injectionpump and the fuel PartsWhen contacting your Westerbeke dealer parts distributor or the factory concerning

Diesel Engines 20 INSTALLATION the crafts in which Westerbeke engines are installed vary in design installation procedures will varyaccording to your crafts specific design The intent of this section is not to advise boatyards or installerson procedures and wellunderstood However the owneroperator must realize thereare details of the installation which require periodic checks to ensure the best operating conditions for theequipment and safe operating conditions for the personnel on board Proper location and installation of thediesel 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 oil 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 dry and in an area where bilge water or water from above cannot splash on the engine The engine should be properly ventilated and accessible for minor servicing and repairs access formajor repairs should be given consideration as well The location must be properly ventilated to providefresh air for engine combustion The engines lubrication oil sump dipstick the fresh water and oil fills andthe transmissions dipstick and transmission or oil fill port must be accessible FILL

plain 21 Westerbeke Diesel EnginesRigging 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 ordesired CAUTION Slings must not be so short as to place significant sheer stress on the engines lifting eyes Strain placed on the engines lifting eyes by the lifting sling must not be in excess of 100 from the vertical plain 10 SLING LIFTING ANGLE MUST NOT EXCEED 10 LIFT ING 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 it is firmly supported Eliminate the possibility of accidents by avoiding haste Do not lift the engine by its 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 otherthan 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 it 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 position as soon as the engine has cleared the obstructionIn 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 Diesel Engines 22Engine BollsBronze 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 its resting place the hanger bolt itself 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 lor the Eng ineA 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 when installedThe temptation to install the engine on a pair offiberglass angle irons must be resisted Such construction will allow engine vibration to pass through GOODto the hull Flexible mounts require a firm which they must act if they are to perform theirfunction When possible follow bed design A andavoid bed design B refer to the illustration ASupports between the bed stringers and extendingfrom the stringers to the hull may be required forproper support and to aid in the absorption of vibrations BAD B Note Avoid excessive height use solid stringer construction A 23 Westerbeke Diesel Shaft CouplingThe propeller shaft coupling fitted to the transmissions output flange must transmit not only the power ofthe engine to turn the propeller shaft and propeller but must also transmit the thrust of the either 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 all engine models a propeller halfcoupling bored to shaft size for the specific order is supplied Thecoupling either has a keyway with set screws or is of the clamping typeThe forward end of the propeller shaft has a long straight keyway Any burrs should be removed from theshafts end The coupling should be a light drive fit on the shaft and the shaft should not have to be scrapeddown or filed in order to get a fit It is important that the key be properly fitted both to the shaft and to thecoupling The key should fit the side of the keyway closely but should not touch the top of the keyway inthe hub of the couplingIf driving the coupling over the shaft is difficult the coupling can be expanded by heating it in a pail of boiling water The face of the propeller coupling must be exactly perpendicular to the centerline or axis of thepropeller type and size of propeller varies with the gear ratio and must be selected to fit the application basedupon boat tests To utilize the full power of the engine and to achieve ideal loading conditions use a propellerwhich will permit the engine to reach its full rated RPM at full throttle while under a normal load and while itis moving the boat forward through the walerAlignment of the EngineThe engine must be exactly aligned with the propeller shaft in the proper fashion No matter what materialis used to build a boat the material will be found to be flexible to some extent hence the boats hull willchange its shape to a greater extent than is usually realized when the boat is launched and operated in thewater Therefore it becomes extremely important to check the engines alignment at frequent intervals andto 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 me 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 seal If oil is leaking from this seal check and make sure that thecouplings alignment is within the limits prescribed on page 25 Never attempt a final alignment with the boa on land The boat should be in the water and have had an op portunity to assume its final water form The best lime to perform the propeller coupling alignment is with the fuel and water tanks about half full and all the usual equipment on board and after the main mast has been stepped and the final rigging has been accomplished Westerbeke Diesel Engines 24Take plenty of time in making this alignment and do not besatisfied with anything less than perfect resultsThe alignment is correct when the shaft can be easily B93 FEELER GAGEslipped backward and forward into the counterbore andwhen a feeler gauge indicates that the flanges cometogether at all points The alignment between the propeller PROPELLER SHAFTshaft coupling and the engines coupling can contain anerror no greater than one thousandth of an inch per inch ofthe coupling diameter For example if your propeller shaftcoupling is three inches in diameter the maximum errorthat can be allowed in the alignment is three thousandthsof an inch 003In making the final check for alignment theengines half coupling should be held in oneposition and the alignment with the tested with the propeller coupling ineach of four 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 dimension A while in each 90 position until the halfcoupling has been rotated full circleThe engines alignment should be recheckedafter the boat has been in service for one tothree weeks and if necessary perform thealignment again Usually it will be found thatthe engine is no longer in alignment This doesnot mean that the work has been done improperly at first rather it means that the boathas taken some time to take its final shape andthat the engines bed and stringers haveprobably absorbed some moisture It mayeven be necessary to realign the coupling halves again at a later time 25 Westerbeke Diesel EnginesExhaust SystemThe exhaust system provides an outlet line to vent engine exhaust gases out 01 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 Theexhaust 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 theexhaust through the circuits throughhull discharge port If not prevented sea water entering through thedischarge 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 lop 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

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 heat 21 Westerbeke Diesel EnginesExhaust 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 surtace 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 manifold should not exceed 8 Ibs in total weight when rigidly connected Excessive weight and vibration can result in a manifold failure andor the fracturing of the riser fromthe manifold at its 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 within the exhaustpipe 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 o Dizziness o Vomiting o Intense Headache o Muscular Twitching o Weakness and Sleepiness o 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 make sure there is no deterioration of the insulation Westerbeke Diesel Engines 28Exhaust Elbow Westerbeke Corporation offers a 45and 900 exhaustelbow as well as an exhaust riser you can install on yourpropulsion engine Refer to the instructions below wheninstalling the exhaust elbow purchased for your engine1 Coat only one side of the exhaust gasket with High Tack adhesive sealant Place this coated surface against the exhaust manifolds exhaust port flange the gasket should stick to the flange without falling off2 Place the clamp over the elbows flange Place your ex haust elbow against the exhaust manifolds flange so the exhaust manifolds flange rests snug against the ex haust elbows flange with the gasket centered between the two Now slip the exhaust clamp over both flanges CLAMP 45 ELBOW3 A Tighten the clamp just enough so the exhaust elbow can remain attached to the manifold and still be rotated B The exhaust elbow discharge must be directed downward so the mixture of sea water and exhaust gases will flowfall downward into the exhaust muf fler which must be positioned below the exhaust elbow There should be no loops or rises in the ex haust hose connected between the exhaust elbow and the muffler as these would trap water and pos sibly allow water to flow back into the engine during ClAMP starting or at shut down 90 ELBOW4 Adjust the elbow by rotating it until the desired align ment with the exhaust piping is acquired5 Carefully tighlen the clamp between 2 to 3 IbI or 24 to 35 Ibin or 02710 041 kgm CAUTION Approach the I Ibf torque limit with caution The clamps threads will break if more than I Ib tI is applied to lhe clamp6 When the engine is started for the first time with the new elbow check Ihis exhaust

hose is installed on the engine with the discharge end secured by a bracket at the front ofthe engine Oil may be drained from this hose by removing the cap and the discharge end of the hose fromthe support bracket and lowering the hose into a container The hose cap fitting is 14 inch NPT NationalPipe Tap and can be extended or have a pump added for easier removal of the old oil if 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 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 discharge 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 throughhull fitting using a wirereinforced hose between the throughhull fitting and the sea water pump The sea water should be a visualtype sea water strainer which will trap debris before reaches the sea water pump and theheat exchanger and then be delivered to the pump Hoses routed from the throughhull fitting to the strainerand to the sea water pump should be wirereinforced to prevent the hose from collapsing while the engineis running suction from the pump may collapse a nonreinforced hose The sea water strainer should bemounted at or below the water line to make sure the sea water line remains primed 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 Diesel Engines 30Automatic Alarm System High Water Temperature AlarmA high water temperature alarm buzzer has been supplied with the instrument panel If the engines freshwater coolant

Key Switch to the OFF position 12 oclock If the Key Switch is left ONthe battery will discharge The alarm buzzer will sound in the Admirals Panel but not in the Captains Panelshould the Key Switch be left ON The best method of preventing the battery from discharge is to removethe key from the Key Switch after stopping the engine CAUTION DO NOT attempt to shutdown the engine by turning the Key Switch OFF The Key Switch only provides power to the instrument panel the engine will continue running even if the Key Switch is turned OFFAn optional key shutoff package is available however This option allows the operator to shutoff the engine by turning the Key Switch OFF which turns OFF an electrically run Fuel Run Solenoid This option is installed at the factory upon the specffic requestorder of the BreakIn your engine has experienced a minimum of one hour of test operations to make sure accurate assembly procedures were followed and that the engine operated properly a breakin time is required Theservice life of your engine is dependent upon how the engine is operated and serviced during its initial hoursof 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 39 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 run the engine at varying engine speeds for the first 25 hours 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 operating the engine with 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 speed Avoid idling the engine for prolonged periods of time 41 Westerbeke Diesel 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 resultsAs 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 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 section of

designed and equipped for fresh water cooling Heat produced inthe engine by combustion and friction is transferred to fresh water which circulates throughout the engineThis circulating fresh water cools the engine block and its internal moving parts The heat is transferred externally from the fresh water to sea water by means of a heat exchanger similar in function to an automotive radiator Sea water flows through the tubes of the heat exchanger while fresh water flows around thetubes engine heat transferred to the fresh water is conducted through the tube walls to the sea water whichis then pumped into the exhaust system where finally it is discharged overboard In other words the engineis cooled by fresh water the fresh water is cooled by sea water and the sea water carries the over the side through the exhaust system The fresh water and sea water circuits are independent ofeach other Using only fresh water within the engine allows the cooling water passages to stay clean andfree from harmful deposits The two independent circuits and their components are discussed in the follow ing Water Circuit NOTE Refer to paragraphs A and B in this section for the recommended antifreeze and water mixture to be used as the fresh water coolant and for information on filling the fresh water systemFresh water is pumped through the engine by a beltdriven circulating pump absorbing heat from the engine The fresh water coolant circulates through the engines block absorbing heat then passes throughthe thermostat into the exhaust manifold to the heat exchanger where it is cooled and then is returned tothe engine block through the suction side of the fresh water circulating pump When the engine is startedcold external fresh water flow is prevented by the closed thermostat although some fresh water flow isbypassed around the thermostat to prevent exhaust manifold from overheating As the engine warms upthe thermostat gradually opens allowing full flow of the engines fresh water coolant to flow unrestricted tothe external portion of the cooling system A Fresh Water Coolant Antifreeze MixtureA freshwater and antifreeze mixture should be used yearround in the cooling system Water when it freezesexpands sufficiently to split the heat exchanger and crack the engine block A waterantWreeze mixture ofproper concentration will prevent freezing see page 53 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 Alwaysuse antrrreeze which is compatible wah 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 for year round use is ZEREX or PRESTONE with rust inhiMorsIn order to control the concentration of the mixture mix the antifreeze and freshwater thoroughly before adding it to the cooling Diesel Engines 52

basis of a temperature which is about 10 F 5 C lower than the actual atmospheric temperature expected B Filling the Fresh Water SystemA coolant recovery tank kit is supplied wtth each Westerbeke diesel engine The purpose of this recoverytank is to allow lor engine coolant expansion and contraction during engine operation without the loss ofcoolant and without introducing air into the cooling systemThis coolant recovery tank should be installed at or above engine manifold level in a location where it canbe easily monitored and where coolant can be easily added if needed see the figure below A stainlesssteel mounting bracket is supplied with each kit along with a 30inch length of clear plastic hose and clampsto connect the hose between the engines manifold fitting to the hose spud on the base of the recovery tank FUNCTION OF MANIFOLD PRESSURE CAP From Coolant Tank COOLANT RETRACTION to Coolant Tank COOLANT from the engine when heated during engine operation will expand lifting the springloaded cap and enter the recovery tank by way of the hose connecting the recovery tank to the manifoldWhen the engine is shut down and cools a small check valve in the pressure cap is opened by the contraction olthe engine coolant allowing some of the coolant in the recovery tank to be drawn back into the enginescooling system Iree of air and without loss Periodically check that the passage A between the 90 littingon the manifold and the filler neck in the manifold is clear so coolant can flow in either direction 53 Westerbeke Diesel Engines COOLANT RECOIIERY TAI 1 i I 1 I 1 I 1 1I Coolant Recovery Tank Recommended the fresh water system as follows1 Remove the pressure cap from the manifold2 Pour a clean antifreeze mixture into the manifold and allow enough time for the coolant to fill the fresh water cooling system3 Start the engine and allow it to come up to its operating temperature Monitor the coolant in the manifold and add antifreeze coolant as air is expelled Once all air is expelled from the system fill the manifold to the filler neck and install the pressure cap4 Remove the plastic cap from the plastic coolant recovery tank and fill the tank with coolant halfway be tween the ADD mark and the MAX mark Replace the plastic cap5 Run the engine and observe the coolants expansion flow into the plastic recovery tank6 Check for leaks between the pressure capfiller neck and then plastic recovery tank Stop the engine and allow it to cool Coolant should be drawn back into the cooling system as the engines temperature comes down7 Add coolant to the recovery tank as required to top off the fresh water coolant thermostats are of two types One is simply a choking device which opens and closes as theengines temperature rises and falls The second type has a bypass mechanism Usually this is a disc onthe bottom of the thermostat which moves downward to close off an internal bypass passage within thehead Since 1980 each type of thermostat has a hole punched through it The hole is a bypass to preventthe exhaust manifold from overheating during the engines warmup Replacement thermostats must havethis design Diesel Engines 54Sea Waler CircuitThe sea water flow is created by a beldriven positive displacement neoprene impeller pump The pump draws seawater directly from the ocean through the sea cock and sea water strainer and pas ses the water to the heat exchangers seawater inlet The sea water passes throughthe heat exchangers lUbes from which i heat from the fresh water system is absorbed and then the sea water is discharged from the cooling through the waterinjected wetexhaust system Be sure to clean zinc CLEAN NEW ORdebris from the area inside of the heat ex ANODE REPLACE REPLACE REPLACEchanger where the zinc anode is positioned Zinc Anode CondttionsA zinc anode or pencil is located in the sea water cooling circuit within the heat exchanger The purposeof the zinc anode is to sacrifice itsell to electrolysis action taking place in the sea water cooling circuit thereby reducing the effects of electrolysis on other components of the system The condition of the zinc anodeshould be checked monthly and the anode cleaned or replaced as required Spare anodes should be carried on boardSea Water PumpThe sea water pump is a selfpriming geardriven rotary pump with a nonferrous housing and a The impeller has flexible vanes which wipe against a curved cam plate within the impeller the pumping action On no account should this pump be run dry There should always be a spareimpeller and impeller cover gasket aboard an impeller kit Sea water failures occur when lubricant seawater is not present Such failures are not warrantable and the operators are cautioned to make sure seawaler flow is present at and Waler Pump Drive Bel Tension IWARNING Never attempt to adjust the drive belts tension while the engine is in operation CAUTION Excessive alternator and water pump drive belt tension can cause rapid wear of the belt and reduce the service lile of the fresh water pump and alternator shaft bearings Excessive slack or the presence 01 oil on the belt can cause belt slipping resulting in high operating tempera ture as well as insufficient alternator output 55 Weslerbeke Diesel EnginesThe alternator and water pump drive belts isare properly adjusted Wthe belt can be deflected no less than38

Westerbeke Diesel Engines LUBRICATION SYSTEMEngine OilFor engine lubrication use lubricating oil designated for diesel service These oils are classified accordingto the API specifications into service grades CA CB CC and CD The use of CC or higher CD gradesmade by 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 10W30 41 F 5 C 68 F 20 C SAE 20 or 10W30 41 F5 C or lower SAE 10W30 NOTE Do not use an engine lubricating oil with an SAE number greater than 30 in the en gineOil PressureThe engines oil pressure during operation is indicated by the oil pressure gauge on the Admirals Panelsee page 37During normal operation the oil pressure will range between 35 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 Diesel Engines 60Engine Oil Change to include IiIter1 Draining the Oil SumpRemove the oil drain hose from its attachment bracket and lower it into a container and allow the oil todrain or attach a pump to the end of the drain hoseand pump the old oil out Make sure the oil drain hoseis

condition is rare it does requireprompt attention to prevent serious damage Call acompetent mechanic should water be present in theoil Sea water present in the oil can be the result of afault in the exhaust system attached to the engineandor a siphoning through the sea water cooling circuit into the exhaust filling it up into the engine referto the installation illustrations on page 262 Replacement of the Oil FilterWhen removing the used oil filter you may find it helpful and cleaner to punch a hole in the upper and lowerportion of the old filter to drain the oil from it into acontainer before removing it This helps to lessenspillage A small style automotive filter wrenchshould be helpful in removing the old oil filter Placesome paper towels and a plastic bag around the filter when unscrewing it to catch any oil left in the filter Oil or any other fluid on the engine reduces the engines cooling ability Please keep your engine clean Inspect the old oil filter as it is removed to make sure that the rubber sealing gasket came offwith the old oil filter If this rubber sealing gasket remains sealed against the engine block gently remove it The replaceable cartridgetype oil filter re quires no cleaning inside so it may be properly dis posed ofWhen installing the new oil filter element wipe the filter gaskets sealing surface on the engine block free ofoil and apply a thin coat of clean engine oil to the rubber gasket on the oil filter Screw the filter onto thethreaded oil filter stub and then tighten the filter firmly by hand NOTE Generic filters are not recommended as the material standards or diameters of im portant items on generic parts might be entirely different from genuine parts Immediately after an oil filter change and oil fill run the

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.
