4.5 Check During Operation

Always be on the lookout for problems during engine
operation. Pay particular attention to the following:
(1) Is sufficient water being discharged from
the seawater outlet pipe?
If the discharge is small, stop the engine immediately,
identify the cause and repair.
(2) Is the exhaust color normal?
The continuous emission of black exhaust gas shows
that the is engine overloading. This shortens the
engine's life and should be avoided.
(3) Are there abnormal vibrations or noise?
Do not operate at speeds, which produce violent
vibrations.
Depending on the hull structure, engine and hull
resonance may suddenly become great at a certain
engine speed range, causing heavy vibrations. Avoid
operation in this speed range. If you hear any abnormal
sounds, stop the engine and inspect.
(4) Alarm buzzer sounds during operation.
If the alarm buzzer sounds during operation, lower the
engine speed immediately, check the alarm lamps,
and stop the engine for repairs.
(5) Is there water, oil, or gas leakage, or are
there any loose bolts?
Check the engine room periodically for any problems.
(6) Is there sufficient oil in the fuel tank?
Replenish fuel oil in advance to avoid running out of
fuel during operation.
(7) When operating the engine at low speed for long
periods of time, race the engine once every 2 hours.

combustion chamber and around the fuel injection
valve.
Neglecting to race the engine will cause the exhaust to
turn black and lower the efficiency of the engine.
