(e) Engine Room
Generally check for any water, fuel or oil leaks. There should be no oil visible anywhere in the engine
room. If there is a leak it must be discovered and fixed. Any oil in this area will be washed into the
bilge and pumped overboard which is illegal.
2. Engine Operation
(a) General
Windward Passage is equipped with a 50HP Yanmar 4JH2E marine diesel engine. The fuel tank holds
approximately 50 gallons of diesel. At an engine speed of 2100 RPM fuel consumption is about 0.75
gallons per hour and speed through the water will be about 5 to 7 knots. This results in a cruising range
under power of about 300 to 400 miles. A factory maintenance manual and a factory parts list are
maintained in the file drawer of ship’s papers.
(b) Starting the Engine
(i) Put the gear selector in neutral position (throttle lever upright). You should be able to push
in the black button on the lever if you are in the neutral position. If the button will not go in,
you are not in neutral.
(ii) Make sure that the fuel cut off cable on the port side of the pedestal is in the down position
(iii) Switch on the black toggle switch on the engine panel. The engine low oil pressure alarm
will activate and stay on until the engine starts and the oil pressure builds to the proper level. If
the alarm continues after the engine has been running for a few seconds, shut the engine down
immediately. There is a problem that can destroy the engine.
(iv) Push the starter button to start the engine. Do not “Rock” the starter. Keep your finger on
the button until the engine starts, provided it does so within 5 seconds. Do not run the starter
continuously for over 5 seconds at a time. If the engine fails to start check that the fuel cut off
cable is pushed all the way down. If the engine fails to start on the first three tries do not
continue to try to start the engine, STOP and check for fuel feeding problems. If a diesel
engine is turned over by the starter but does not start it is almost always a result of a fuel
blockage, being out of fuel or having air in the fuel feed line.
(v) When the engine starts, check that engine cooling water is coming out of the exhaust. The
exhaust is located in the starboard side of the stern. It is normal for the exhaust to surge but
there should be visible water coming out in spurts.
(vi) If you want to run the engine to charge the belt driven refrigerator compressor or use the
anchor windlass you must increase the engine speed to about 1200 rpm. To do this without
having the propeller engaged you hold in the black button on the gear shift lever while in
neutral and pull the lever back until the desired engine speed is attained. The button should stay
in when you release it and the propeller should not be turning.
(c) Stopping the Engine
Do not turn off the black toggle switch on the engine panel while the engine is running. To stop
the engine pull the fuel shut off cable located on the port side of the pedestal. This turns off the supply
of diesel fuel and the engine will stop in a second or two. When the engine stops, the low oil pressure
alarm will sound. Turn the toggle switch off and the alarm will go off. Then push the fuel shut off
cable to the down position.
