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

If the instrument panel has an ignition switch the

key should be 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.

If the boat is fitted with an electric start/stop func-

tion: Push the rocker switch to the ”Stop” position un-

til the engine stops. Release the rocker switch and it

returns automatically to the ”Power OFF” position.

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.

● Read off the hours counter and do preventive

maintenance as in the maintenance schedule.

● 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.

Cold weather precautions

To prevent freezing damage, the seawater system

must be drained and the freshwater system coolant

must have sufficient antifreeze protection. See

chapter Maintenance ”Cooling systems”.

IMPORTANT! A poorly charged battery may

burst as a result of freezing.

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”.
