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 sucient 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.
tip!
Combine ushing the raw water circuit
with fresh water with running the en-
gine with the protective fuel mixture,
see ‘Winter storage procedure - Protec-
tive fuel mixture’
Heat exchanger
Only clean the heat exchanger if this is
absolutely necessary, see page 72.
Raw water pump
Check the impeller of the raw water
pump at least once every two years, see
page 64.
