Engine Safety Precautions
Due to high temperatures it is recommended that after running the diesel for more than two hours you
reduce speed to idle and allow excess heat to dissipate for five to ten minutes.
The most common cause of trouble is contaminated or dirty fuel. Your boat is equipped with a Racor
fuel filter located in the engine compartment and a secondary filter on the engine. The wise skipper
carries replacement filter cartridges. The dual filter is designed so that one filter is in operation while the
other is a spare. This way you can switch the fuel flow through the spare filter, if you need to change
out the first one.
Familiarize yourself with the bleeding procedure for the engine and try bleeding it yourself. The
procedure only takes a few minutes after you are acquainted with it, but can be exasperating to the
uninitiated.
Starting Up The Engine
1) Turn the battery selector switch to ALL. Turn off all electronic instruments to avoid a voltage spike to
the instruments while cranking the engine.
2) Make sure that throttle control is in neutral
3) Turn the ignition key to the ON position. The engine-alarm buzzer will sound and the warning lights
for low oil pressure and charging will light up. (The alarm and warning lights will continue until the
engine starts or the key is turned off.) If the alarm does not sound, use the engine-alarm test switch on
the engine instrument panel to verify that the engine alarm is working.
4) If the engine-alarm is working correctly, press the START button. Release the button immediately
when the engine starts. If the engine does not start in 10 seconds, turn off the key. Advance the
throttle slightly, wait 10 seconds, and repeat steps 3 and 4.
5) When the engine starts, the oil-pressure and charging warning light will go out and the engine-alarm
buzzer will stop. If they do not, stop the engine immediately.
6) Once the engine starts, set the throttle at about 1,000 RPM. If all engine indications are normal,
warm up the engine for 10 minutes.
7) Test the operation of FORWARD and REVERSE gears at the dock with the docklines in place.
CAUTION: If the engine does not start after a pro-longed period (do not exceed 10 seconds at a time)
of cranking, be sure to drain the water-lock muffler and exhaust loop. Accumulated water may flow
back into the engine manifold and damage the engine.
IMPORTANT: Check that a flow of raw-water cooling water is exiting from the transom. If cooling water
is not being discharged, the engine will burn up: shut down the engine immediately. Check that the
raw-water strainer basket is free of blockage. Check that the raw-water engine-intake valve is open on
the Saildrive leg. If necessary, check underneath the hull to make sure that the raw-water intake on the
Saildrive is not blocked.
Shuting Down The Engine
1) Move the throttle to the IDLE (vertical) position.
2) Run the engine at IDLE long enough to allow the engine to cool down.
