ENGINE OPERATION

46 6LPA Series Operation Manual

NOTICE

Racing the engine: With the gear 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 valve. Neglecting to race the

engine will result in poor smoke color

and reduce engine performance.

• If possible, periodically operate the

engine at near maximum engine speed

while underway. This will generate higher

exhaust temperatures, which will help

clean out hard carbon deposits,

maintaining engine performance and

prolonging the life of the engine.

NOTICE

NEVER turn off the battery switch (if

equipped) or short the battery cables

during operation. Damage to the electric

system will result.

SHUTTING DOWN THE

ENGINE

Normal Shutdown

1. Reduce engine speed to low idle and

put remote control handle in NEUTRAL.

2. Accelerate from low speed to high

speed and repeat five times. This will

clean out the carbon from the cylinders

and the fuel injection nozzles.

3. Allow engine to run at low speed

(approximately 1000 min

-1

) without load

for 5 minutes.

NOTICE

For maximum engine life, Yanmar

recommends that when shutting the

engine down, you allow the engine to

idle, without load, for 5 minutes. This will

allow the engine components that

operate at high temperatures, such as

the turbocharger and exhaust system, to

cool slightly before the engine itself is

shut down.

4. With the key in the ON position, push and

hold the STOP button (Figure 7, (1)).
