ENGINE OPERATION
CAUTIONS DURING
OPERATION
NOTICE
Engine trouble can arise if the engine is
operated for a long time under overloaded
conditions with the control handle in the full
throttle position (maximum engine speed
position), exceeding the continuous rated
output engine speed. Operate the engine
-1
at about 100 min
throttle engine speed.
Note: If the engine is in the first 50
hours of operation, see New
Engine Break-In on page 16 .
Always be on the lookout for problems
during engine operation.
Pay particular attention to the following:
• Is sufficient seawater being discharged
from the exhaust and seawater outlet
pipe?
If the discharge is small, stop the engine
immediately; identify the cause and
repair.
• Is the smoke color normal?
The continuous emission of black
exhaust smoke indicates engine
overloading. This shortens the engines
life and should be avoided.
