Seawater System
The seawater system is the engine’s external cooling
system. The seawater system sucks in water through
the seawater inlet and pumps it through the heat
exchanger and the reversing gear oil cooler. The
system is protected from galvanic corrosion by means
of zinc anodes located in the heat exchanger and the
reversing gear oil cooler.
WARNING!
Risk of water entry. Water will flow into the boat if any
hose, plug etc. located below the waterline is removed
when the boat is in the water. Always close the sea
cocks. If the boat does not have sea cocks the water
flow must be blocked in a safe manner. If this is not
possible, the boat must be drawn up on land before
work starts.
Seawater System, Draining
1 Close the raw water in- and outlet cocks.
2 Connect a suitable hose to each drain point (S).
Open the drains and allow the raw water to drain off
into a suitable vessel.
IMPORTANT:
Check that all water really does drain out. Deposits
may need to be cleared away, inside the drain plug/tap.
