STARTING PROCEDURE
1. Depress and hold the preheat switch. Preheat according to the following chart.
2. While still depressing the PREHEAT switch, depress the START switch. As soon as the engine runs,
release the START switch but continue to hold the PREHEAT switch depressed for an additional 2 - 3
seconds. This allows the engine to build up enough oil pressure to close the oil pressure shutdown switch
and allow the engine to continue to run.
NOTE: Should the engine not start when the START switch is depressed for 10 - 12 seconds,
release both switches and wait 30 seconds; repeat the previous procedure. Never run the starter
motor for more than 30 seconds at a time.
3. Check all instruments on the panel for proper operation. Make sure raw water discharges with the
exhaust discharge.

+23 0 F (_50 C) or lower
Limit of continuous use
Once the engine starts, allow it to run for a few
minutes to warm up and stabilize while the engine's
instruments are checked for proper oil pressure and
battery charging voltage. Never attempt to engage
the starter while the engine is running.
NOTE: Some unstable running may occur in
a cold engine, but this condition should
smooth out as the operating temperature of
130 - 150 0 F (55 - 56 0 C) is reached.
Proper glow plug function is indicated by a voltmeter
drop when the PREHEAT switch is depressed. This
drop will be slight but discernible.
If no voltage
drop is noted, it may indicate defective glow plugs or
a faulty preheat circuit (check for loose connections).

CAUTION
II
Prolonged cranking intervals without the engine starting can result in filling the engine-mounted exhaust
system with sea water coolant. This may happen because the sea water pump is pumping sea water
through the sea water cooling system during cranking. This sea water can enter the engine's cylinders by
way of the exhaust manifold once the exhaust system fills. Prevent this from happening by closing the sea
water supply through-hull shut-off, drain the exhaust muffler, and correct the cause for the excessive
engine cranking needed to obtain a start. Engine damage resulting from this type of sea water entry is not
a warrantable issue; the owner/operator should keep this in mind.
