3. Operation

25

(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.

Electric Operation

(4) Alarm buzzer sounds during oper-

ation.

If the alarm buzzer sounds during

operation, lower the engine speed

immediately, check the warning 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 fuel oil in the fuel

oil tantk?

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.

Note: Racing the Engine

With the clutch in NEUTRAL,

accelerate from the low speed

position to the high speed position

and repeat this process about 5

times. This is done to clean out

carbon from the cylinders and the

fuel injection valve.

Neglecting to race the engine will

result in poor exhaust colour and

reduce engine performance.

Electric Operation

Never turn off the battery switch or

spark the battery cable during

operation. Damage to parts in the

electric system will result.

3.3.5 Stopping the Engine

Stop the engine in accordance with the

following procedures:

1. Put the remote control handle in NEU-

TRAL.

2. Be sure to race the engine before stop-

ping it. (See 3.3.4(7))

3. Cool down the engine at low speed

(approximately 1000 rpm) for about 5

minutes.

Stopping the engine suddenly while

operating at high speed will cause the

engine temperature to rise quickly,

causing deterioration of the oil and

sticking of parts.
