could allow water to leak into the
boat and may cause it to sink.

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 15 seconds or until
the engine starts. When the
engine does start, stop the
engine immediately and press
the switch to the OFF position.
• Be sure to re-open the seacock
and restart the engine. Operate
the engine normally.

CAUTION
Observe the following
environmental operating
conditions to maintain engine
performance and avoid
premature engine wear:
• NEVER run the engine if the
ambient temperature is above
+40°C (+104°F) or below -16°C
(+5°F)
◆
If the ambient temperature
e40°C (+104°F) the
engine may overheat and
cause the engine oil to break
down.
◆
If the ambient temperature
falls below -16°C (+5°F)
rubber components such as
gaskets and seals will
harden causing premature
engine wear and damage.
◆
See your authorized Yanmar
marine engine dealer or
distributor if the engine will
be operated in either
temperature extreme.
• See your authorized Yanmar
marine dealer or distributor if
you need to operate the engine
at high altitudes. At high
altitudes the engine will lose
power, run rough, and produce
exhaust gases that exceed the
design specifications.
