Yanmar 6LY3 series Operation Manual page 23

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).

CAUTION
New Engine Break In:
• On the initial engine start-up,
check for proper engine oil
pressure, diesel fuel leaks,
engine oil leaks, coolant leaks,
and for proper operation of the
indicators and / or gauges.
• During the first 50 hours of
operation operate your new
engine under a substantial
load at all times. For best
break-in results operate the
engine at various speeds.
• Operating the engine in
NEUTRAL must be avoided.
During the first 50 hours, avoid
operation below 2000 rpm.
• During the break-in period,
carefully observe the engine
oil pressure and engine
temperature.
• During the break-in period,
check the engine oil and
coolant levels frequently.
CAUTION
NEVER allow engine oil or diesel
fuel oil to contact the flexible
rubber mount. Oil makes rubber
deteriorate.
