7 Winter storage procedure
4 Raw water cooling system
• Close the sea cock.
• Remove the lid of the water strainer.
• If necessary, clean the raw water strainer.
• Connect the raw water intake to a fresh wa-
ter (tap water) supply or a tank containing
fresh water. Open the tap and allow the en-
gine to idle for at least 5 minutes to remove
any salt and contamination from the raw
water cooling system.
Make sure that there is a sufficient supply
of water to prevent the engine from over-
heating.
• Stop the engine and close the sea cock.
• The raw water system must be protected in
areas where the temperature drops to be-
low zero during the winter.
Pour 1 litre (1/4 gallon) of anti-freeze (prefer-
ably a non-toxic biodegradable anti-freeze)
into the water strainer and run the engine
until the anti-freeze has disappeared into
the cooling system.
