Shut down the unit and do not restart until it has been inspected and repaired. This WARNING DECAL is provided by WESTERBEKE and should be fixed to a bulkhead near your engine or generator. WESTERBEKE also recommends installing CARBON MONOXIDE DETECTORS in the living/sleeping quatters of your vessel.

FOREWORD Thank you for having selected a Westerbeke Diesel Engine for your use. This manual describes the procedures for proper handling and main- tenance of the Engine Models W13, W21, W27 and W33. To maintain your engine always in its best operating condition and...
CAUTIONS IN HANDLING ENGINE Always use proper engine oil and watch oil pressure during opera- tion. Use clean fuel, free from impurities and water content. Prevent entry of air and water into the fuel system. In case the starter motor pinion fails to engage wi th the ring gear at the time of starting,...
BREAKING IN Service life your engine dependent upon how your engine operated and serviced during the initial 50 hours of operation! Your new engine needs 50 hours conditioning operation breaking each moving part and maximizing performance and life of engine. Perform this conditioning carefully, bearing the following points in mind:...
PREPARATIONS Take steps as shown below in starting your engine for the first time or after a prolonged shut-down. Fill your engine with oil up to or near the upper limit on the dipstick. Use a good grade of wi th API specification of CC or better.
STARTING PROCEDURES Instrument panel, description and use of: Note 1: When engine is stopped after use, the water temperature and oil pressure gauges may stay at their running readings. Note 2: When engine is next to be used, turn start switch to "ON". The temperature and pressure gauges will "ZERO"...

STARTING PROCEDURES Turn the starter swi tch to the "ON" position_ If making ini tial star t after lay-up, fuel filter servicing repairs, allow fuel pump work 15-25 seconds to purge the system of any air. Check that clutch is in neutral and that throttle is in full forward_ Glow plug preheating...

LUBRICATING OIL TURNS VISCOUS Make certain that oil used adequate prevailing atmospheric temperature. Check the oil also for deterioration. VOLTAGE ACROSS BATTERY TERMINALS DROPS Check that the battery is fully charged. TEMPERATURE INTAKE COMPRESSION TEMPERATURE DOES NOT RISE ENOUGH Allow the glow plug to operate sufficiently to aid starting.
REQUIREMENTS FOR PROPER OPERATION LUBRICATION SYSTEM Engine oil For engine lubrication, use diesel engine oil. Diesel engine oils are classified according to the API Specifications into grades CA, CB, CC and CD. Anyone of them is usable, but use of CC or higher grades prepared by well-known makers is recommended.
Replacement of oil filter Being a replaceable cartridge type, the oil filter requires no cleaning inside. In installing the oil filter, apply engine oil thinly on to the O-ring, and then tighten it by hand firmly. When removing the used filter, cover over with a plastic bag.

Notes on fuel system See below a typical exploded view of a fuel system. The one shown is for the W13. Those for the W21, W27 and W33 are similar except for the number of cylinders. The Wes·terbeke self-bleeding fuel system is automatic in opera- tion.

If a leak should develop at banjo or washer that cannot be remedied by a simple tightening of the screw, renew the washers. The engine can be started by taking the steps described on pages 8 and 9. In cases where the engine cannot be started easily, loosen two injection nuts on the nozzle side, turn the speed control...

Fresh water cooling system (See Note 5 on page 6.) The system consists of a sea water pump which pumps raw sea water through a heat exchanger to remove heat from the coolant. The raw water is discharged overboard through the exhaust line. The engine coolant (fresh water with or without antifreeze) circulated by the fresh water pump in continuous circuit.
WIRING DIAGRAM Your engine is of l2V system and its electric circuit is as shown in the diagram below. For installing electrical parts, connect them correctly by referring same time check for damaged wire sheathing to the diagram and at the is provided properly.
RECOMMENDED MAINTENANCE SERVICE Check and service your engine at specified intervals to maintain it in its best conditions and permit it to perform as it should. As for those asterisked items, it is suggested that you have them performed by an authorized distributor or dealer. Daily inspection before use Checkup of engine oil level and refilling No refill is required if the level is near the upper limit...

Checkup of compression pressure Remove each glow plug and check cylinders, one by one, using compression pressure gauge. If the pressure differs by more than 2.5 kg/cm 2 (35.6 psi) between cylinders or if the kg/cm 2 cylinder pressure less than (369.8 psi)
