So as to protect your engine well during the standstill of
the winter season, it is recommended to have the
engine running for some 10 minutes with a protective
mixture of 10% lubrication oil and 90% of clean diesel
fuel. Replace the oil filter and change the engine lubrication
oil with a good quality of oil, with protective properties.
See page 21.
Protective fuel mixture
Lubrication oil system
Raw water cooling system
Close the raw water seacock, open the water strainer
cover and start the engine while adding antifreeze until
the sea-water circuit is filled completely. Place a bucket
underneath the exhaust exit to catch any excessive
antifreeze while running the engine. Anti freeze is
poisonous and must be disposed of correctly. Remove
the impeller during winter storage (see page 24).
When closing the cover of the raw water strainer, make
sure that it tightens well. If false air is coming into the
system through a cover that is not closed tightly, there
is a severe risk of overheating of the engine.
Do not load the engine with this
mixture. Idle speed only!
Anti-freeze liquid is very poisonous!
Make sure anti-freeze is not getting into
the waterway.
