Stopping The Engine - Yanmar 6LYA-STP Bedienungsanleitung

How to Race the Engine
Repeat a cycle of high speed and low speed operation about 5 times at no load with
the clutch (marine gear) in Neutral position.
Engine racing removes carbon deposits from the cylinder and the tip of the fuel
injection valve.
If racing is neglected, the exhaust color may worsen and performance may drop.

3.3.5 Stopping the Engine

Stop the engine according to the following procedures:
1) Shift the remote control leve to low engine speed and handle to Neutral position to stop the
boat.
2) Be sure to race the engine before stopping.
3) Operate the engine at low speed (approx. 1000rpm) for about 5 minutes to decrease the
engine temperature.
[ NOTICE ]
If engine is stopped quickly during high speed operation, the engine temperature
will rise sharply, causing lube oil to degenerate and moving parts to stick.
4) Press the stop button until the engine stops completely. If you release the button early, the
engine may continue running.
5) Turn the starter switch to OFF. Pull out the key
and store it carefully
6) Turn the battery switch off.
7) Close the fuel tank cock.
8) Close the kingston cock.
[ NOTICE ]
Be sure to close the kingston
cock, or water may enter and
sink the boat.
