Stopping The Engine; After Stopping The Engine; Laying Up; Cold Weather Precautions - Volvo Penta MD2010 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
Pull and hold out the stop control until the engine has stopped. Push in
the stop control. If the instrument panel has an ignition switch the key
should turned to the stop position "S". The key will automatically spring
back to the "0" position when it is released and can then be removed.

After stopping the engine

Inspect the engine and engine compartment for any leaks.
Close the fuel cock and sea cock for the cooling water intake.
IMPORTANT! Do not forget to open the cocks before the engine is
started again.
Switch off the main switch 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 being left in the
water, the engine must be run to operating temperature at least once
every 14 days. This prevents corrosion in the engine. If the boat will not
be used for more than two months then inhibiting should be carried out:
See chapter "Laying up/Launching".

Cold weather precautions

To prevent freezing damage, the seawater system must be drained and
the freshwater system coolant must have sufficient antifreeze protec-
tion. See chapter Maintenance "Cooling systems".
IMPORTANT! A poorly charged battery may burst as a result of
freezing.
