TROUBLESHOOTING
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 2 hours. Racing 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 the race the engine will
result in poor exhaust color and reduce
engine performance.
