CAUTION
For maximum engine life,
Yanmar recommends that when
shutting the engine down, you
allow the engine to idle, without
load, for 5 minutes. This will
allow the engine components
that operate at high
temperatures, such as the
turbocharger (if equipped) and
exhaust system, to cool slightly
before the engine itself is shut
down.

CAUTION
NEVER use an engine starting
aid such as ether. Engine
damage will result.

CAUTION
Make sure the engine is installed
on a level surface. If a Yanmar
Marine Engine is installed at an
angle that exceeds the
specifications stated in the
Yanmar Marine Engine Operation
Manual, engine oil may enter the
combustion chamber causing
excessive engine speed, white
exhaust smoke and serious
engine damage. This applies to
engines that run continuously or
those that run for short periods
of time.

CAUTION
Be careful not to get any oil on
the V-belt. Oil on the belt causes
slipping and stretching. Replace
the belt if it is damaged.

CAUTION
If seawater is left inside of the
engine, it may freeze and
damage parts of the cooling
system when the ambient
temperature is below 0°C (32°F).
0000154en
CAUTION
NEVER allow engine oil or diesel
fuel oil to contact the flexible
rubber mount. Oil makes rubber
deteriorate.
