Shutdown procedure
1. Let the engine run at idling speed for about 1 min
after operation (with reverse gear/S-drive in the
neutral position). This will ensure an equalisation
of temperature in the engine and prevent “after-
boiling”.
2. Stop the engine by turning the key switch to the
“S” position. Hold the key in stop position until
engine is of and release it (the key will automati-
cally spring back into the “0” position). You may
then remove the key.
Safety measures:
3. Disconnect the main switch if the boat is not to be
used for some time.
WARNING! Never disconnect the main
switch when the engine is running. If you
do, the voltage regulator and alternator may
be seriously damaged.
4. Check there are no leaks around the engine and
that everything in the engine room looks normal.
5. Close the sea cock (cooling water intake) and the
fuel cocks.
In risk of frost
In cold weather, where there is a risk of freezing, it is
important that the coolant in the freshwater system has
sufficient antifreeze and that the sea water system is
drained.
The fresh water system shall, if filled with a liquid
without any frost protection, be drained through the
plug (1) on the right hand side of the engine block and
through the plug (2) at the exhaust pipe. The oil cooler
is drained through the plug (3), (not MD22L). Remove
the heat exchanger filler cap to allow the water to run
out more quickly. If the system is filled with a liquid
with frost protection then it does not need to be
drained.
!CAUTION: Refit the plugs and replace the cover
before you leave the boat.
