Are there abnormal vibrations or noise?

Depending on the hull structure, engine and

hull resonance may suddenly increase at

certain engine speed ranges, causing heavy

vibrations. Avoid operation in this speed

range. If any abnormal sounds are heard,

stop the engine and inspect for the cause.

Alarm sounds during operation.

If the alarm sounds during operation, lower

the engine speed immediately, check the

warning lamps and stop the engine for

repairs.

Is there water, oil or fuel leakage? Are

there any loose bolts or connections?

Check the engine room daily for any leaks

or loose connections.

Is there sufficient fuel in the fuel tank?

Refill the fuel tank in advance to avoid

running out of fuel. If the tank runs out of fuel,

bleed the fuel system.See Air Bleeding from

the Fuel System After Starting Failure on

page 34.
