Stopping The Engine; Stopping; Laying Up - Volvo Penta D4 Operator's Manual

Stopping the engine

The engine should be run for a few minutes at idle (in neutral) before turning it off. This will avoid boiling and even
out the temperature. This is especially important if the engine has been operated at high engine speeds and
loads.

Stopping

Turn the key to stop position "S". Keep the key turned until
the engine stops. The key will automatically return to the
"0" position when it is released and can then be removed.
Auxiliary stop
If the engine cannot be stopped in a normal procedure, it is
possible to stop the engine via auxiliary stop mounted on
the side of the engine.
After stopping the engine
●
Close the fuel cock and sea cock (reverse gear) for the
cooling water intake.
IMPORTANT! Do not forget to open the cocks be-
fore the engine is started again.
●
Inspect the engine and engine compartment for any
leaks.
●
Boats with drives: The drive must be trimmed in to its
maximum to protect the trim cylinders untreated surfac-
es from fouling.
IMPORTANT! If there is a risk that the drive can
run aground, it must instead be trimmed out to its
maximum lift position.
●
Switch off the main switches if the boat is not to be
used for some time.
IMPORTANT! Never break the circuit with the main
switches while the engine is running. This could
damage the generator.

Laying up

If the boat is not going to be used for some time but is be-
ing left in the water, the engine must be run to operating
temperature at least once every 14 days. This prevents the
corrosion in the engine. If the boat will not be used for
more than two months then inhibiting should be carried out:
