CAUTION
• 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 15
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 the
switch to the OFF position.
• Be sure to re-open the seacock and restart
the engine. Operate the engine normally.
NOTICE
If any indicator illuminates during engine
operation, stop the engine immediately.
Determine the cause and repair the problem
before continuing to operate the engine.
If the alarm window with audible alarm fails
to display and go out about 3 seconds later
when the ignition switch is in the ON
position, see your authorized Yanmar
Marine dealer or distributor for service
before operating the engine.
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 +40C (+104F) or
below -16C (+5F).
• If the ambient temperature e40C
(+104F), the engine may overheat and
cause the engine oil to break down.
• If the ambient temperature is below -16C
(+5F), 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.
