JH Series Operation Manual

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 fuel in advance to avoid running out 
of fuel. If the tank runs out of fuel, bleed 
the fuel system. 

See Bleeding the Fuel 

System on page 40

.

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 to race the engine will result in 
poor smoke color and reduce engine 
performance.

Periodically operate the engine near 
maximum speed while underway. This will 
generate higher exhaust temperatures, 
which will help clean out hard carbon 
deposits, maintain engine performance 
and prolong the life of the engine.

TROUBLESHOOTING 
INFORMATION

If the engine does not operate properly, 
refer to the 

Troubleshooting Chart on page 

105 

 or consult authorized Yanmar Marine
