TROUBLESHOOTING

Before performing any troubleshooting

procedures within this section, review the

Safety section on page 3.

If a problem occurs, stop the engine

immediately. Refer to the SYMPTOM

column in the Troubleshooting Chart to

identify the problem.

TROUBLESHOOTING

AFTER STARTING

Just after the engine has started, check the

following items at a low engine speed:

Is sufficient water being discharged

from the seawater outlet pipe?

If the discharge is low, stop the engine

immediately. Identify the cause and repair.

Is the exhaust color normal?

The continuous emission of black exhaust

smoke indicates engine overloading. This

shortens the engine’s life and should be

avoided.

When operating the engine at low speed for

long periods of time, race the engine once

every two hours. Race the engine with the

clutch in NEUTRAL, accelerate from the low

speed position to the high speed position

and repeat this process about five times.

This is done to clean out carbon from the

cylinders and the fuel injection valves.

NOTICE: Neglecting to race the engine

will result in poor exhaust color and

reduce engine performance.

Periodically operate the engine near

maximum speed while under way. This will

generate higher exhaust temperatures,

which will help clean out hard carbon

deposits, maintain engine performance and

prolong the life of the engine.
