ENGINE OPERATION
38 GM Series Operation Manual
To prevent accidental equipment
movement, never start the engine in
gear.
Sever Hazard
Keep children and pets away
while the engine is operating.
If any indicator illuminates during engine
operation, stop the engine immediately.
Determine the cause and repair the
problem before you continue to operate
the engine.
If the alarm indicator with audible alarm
fails to display and go out about 3 seconds
after the ignition switch is turned on,
consult authorized Yanmar Marine dealer
or distributor for service before operating
the engine
If the vessel is equipped with a water lift
(water lock) muffler, excessive cranking
could cause seawater to enter the
cylinders and damage the engine. If the
engine does not start after cranking for 10
seconds, close the thru-hull water intake
valve to avoid filling the muffler with water.
Crank for 10 seconds at a time until the
engine starts. When the engine does start,
stop the engine immediately and turn off
the switch.
Be sure to re-open the seacock and restart
the engine. Operate the engine normally.
Observe the following environmental
operating conditions to maintain engine
performance and avoid premature engine
wear:
• Avoid operating in extremely dusty
conditions.
• Avoid operating in the presence of
chemical gases or fumes.
• Never run the engine if the ambient
temperature is above +40°C (+104°F) or
below -16°C (+5°F).
• If the ambient temperature exceeds
+40°C (+104°F), the engine may
overheat and cause the engine oil to
break down.
• If the ambient temperature is below
-16°C (+5°F), rubber components such
as gaskets and seals will harden causing
premature engine wear and damage.
• Contact your authorized Yanmar Marine
engine dealer or distributor if the engine
will be operated outside of this standard
temperature range.
Never engage the starter motor while the
engine is running. Damage to the starter
motor pinion and / or ring gear will result.
