After stopping

General

* Check the engine and engine room for leaks.
* Close the fuel cock and seawater cock.
IMPORTANT! Do not forget to open the cocks before starting the engine again.
* Read off the hour counter and carry out preventive maintenance according to the maintenance schedule.
* Turn off the main switch if the engine is not to be used for a long period.
IMPORTANT! Never turn the power off using the main switch while the engine is running. This can
damage the alternator.

Anti-freezing measures

If the engine room cannot be protected from frost, the sea-water system must be drained and the coolant in the
fresh-water system must contain sufficient anti-freeze to prevent it from freezing. Refer to chapter Maintenance
"Seawater system" and "Freshwater system" respectively.
WARNING! If the seawater system bursts due to freezing, it is possible for the vessel to sink.
IMPORTANT! If the coolant does not give sufficient anti-freeze protection, it may cause costly damage
to the engine. Check the charge of the battery. A poorly charged battery can freeze and break.

Breaks in operation [not using the engine]

During periods out of service, when the boat is in the water, the engine must be run warm once a fortnight. This
will prevent the engine from corroding.
IMPORTANT! The engine must be conserved if it is not to be used for longer than two months. Refer to
chapter Inhibiting.
