SAFETY
CAUTION
• NEVER overfill the engine with
engine oil.
• ALWAYS keep the oil level
between upper and lower lines
on the oil cap / dipstick.
CAUTION
For maximum engine life,
Yanmar recommends that when
shutting the engine down, you
allow the engine to run, without
load, for five minutes. This will
allow the engine components
that operate at high
temperatures, such as the
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 Installation
manuals, 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 belt(s). 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).
CAUTION
NEVER allow engine oil or diesel
fuel oil to contact the flexible
rubber mount. Oil makes rubber
deteriorate.
