  • Page 12: Installation Checks

    INSTALLATION CHECKS General Because the crafts in which Westerbeke engines are installed vary in design, installation procedures will vary according to your craft's specific design. It is not the intent of this section to advise boatyards or installers on procedures alreadywell-developed and well-understood. However, it is important that the owner/operator realize there are details of the installation which require periodic checks to ensure the best operating condi- tions for the equipment and safe operating conditions for the personnel on board.
  • Page 13 In case it becomes necessary to hoist the engine either front-end upwards or transmission-end upwards, the attachment of slings must be done carefully to avoid the possibility of damaging the parts on which the weight may bear.

  • Page 17 Exhaust System The exhaust system provides an outlet line to vent engine exhaust gases out of and away from the vessel. The system also discharges sea water which has passed through the engine's sea water circuit by mixing it with hot exhalJst gases. This mixing helps cool the exhaust gases and exhaust elbow and plumbing. The ex- must haust system and the sea water supply to the exhaust be configured to prevent the siphoning of sea...

    Follow the procedures as presented, for the conditions indicated, and your Westerbeke engine set will give you reliable performance and long service life. Fill your engine with oil up to or near the upper limit on the dipstick (the installation angle may have an effect on the dipstick reading).
  • Page 24 This system is common to Westerbeke Diesels. The start circuitry is designed so that the PREHEAT button must be depressed for the time specified in the "Preheat" chart shown on page 26. Then, while keeping the PREHEAT button engaged, the START button is depressed to crank the engine.

  • Page 25: Description Of Instrument Panels

    DESCRIPTION OF INSTRUMENT PANELS Westerbeke offers two types of control panels as optional equipment for the W 12B engine. Read the follow· ing instructions that apply to the panel you purchased with your engine. Captains Panel General This manually-operated control panel is equipped with a key switch, an RPM gauge, a PREHEAT and START button, and an instrument test button along wtth a low oil pressure/high water temperature alarm.
  • Page 26 5.6Iarm: The alarm is located above the lest button and will sound if the engine's oil pressure falls below apulsating psi. In this event, the alarm will emil signal. The alarm will also sound if the water tempera- continuous ture in the fresh water cooling circuit rises to 210' F.
  • Page 27 The buzzer will sound when the ignition key is turned ON and should silence when the engine has started and when the engine's oil pressure rises above 15 psi. Westerbeke Diesel Engines...

  • Page 32: Fuel System

    Although most boatbuilders supply a water trap/filter, some do not. Westerbeke offers a sedimentary/water trap/filter as an optional extra at moderate cost. The filter is supplied with fittings for etther hose or metal tubing fuel lines.
  • Page 33 Priming the Fuel System The Westerbeke self-bleeding fuel system is semiautomatic in operation. The self-bleeding feature of the fuel system allows for easy servicing of the fuel filters. Simply remove the and replace the filter elements (take care in catching any fuel that may drain out of the fuel filtering assemblies) as described in the "Replacing the Fuel Filter Elements"...
  • Page 34 To obtain long and satisfactory service from the injection pump, always use fuel which is free from impurities and maintain a good filtration and water separation system between the fuel tank and generator engine.

  • Page 41: Cooling System

    COOLING SYSTEM Description Westerbeke marine diesel engines are designed and equipped for fresh water cooling. Heat produced in the engine by combustion and friction is transferred to fresh water which circulates throughout the engine. This circulating fresh water cools the engine block and its internal moving parts. The heat is transferred external- ly from the fresh water to sea water by means of a heat exchanger, similar in function to an automotive radiator.
  • Page 42 B. Filling the Fresh Water System A coolant recovery tank kit is supplied with each Westerbeke diesel engine. The purpose of this recovery tank is to allow for engine coolant expansion and contraction, during engine operation, Without the loss of coolant and without introducing air into the cooling system.
  • Page 43 Since 1980, each type of thermostat has a hole punched through it. The hole is a bypass to prevent the ex- haust manifold from overheating during the engine's warm-up. Replacement thermostats must have this design characteristic. Westerbeke Diesel Engines...
