Seawater System, Cleaning and
Inhibiting
The sea water system must be flushed with fresh water
to prevent the build-up of deposits and salt crystals. It
must also be conserved when the boat is laid up.
WARNING!
Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
WARNING!
Working with or approaching a running engine is a
safety risk. Watch out for rotating components and hot
surfaces.
1 Disconnect the hose from the seawater pump and
install a hose which runs to a bucket filled with fresh
water. Make arrangements for topping up.
IMPORTANT!
The impeller will be damaged if it is run dry.
2 Check that there is no one in the vicinity of the pro-
peller and that nothing risks being spattered by the
exhaust outlet.
3 Put the gear selector in neutral. Start the engine
and let it run at idle for a few minutes.
Stop the engine.
4 Fill the bucket with a mixture of 40% glycol and 60%
fresh water, to conserve the system. Place a bucket
at the exhaust outlet to collect the mixture.
5 Start the engine and let it idle. Stop the engine just
before the mixture is used up. Repeat until the
entire system has been flushed with the mixture.
6 Re-install the seawater hose
7 The system is now conserved. The glycol mixture
must remain in the system during storage.
Drain the mixture before the boat is launched Hand
the mixture to a recycling station
