Maintenance: Seawater system

Vacuum valve. Cleaning

Some engines have a vacuum valve installed in the

seawater piping.

WARNING! Risk for water penetration. Close the

sea cock.

Close the sea cock. Disassemble the valve. Unscrew

the hexagonal cover. In the cover there is a mem-

brane and a gasket. Clean all the parts. Turn the

cover upside down. Install the membrane ﬁrst and

then the gasket. Turn the valve housing upside down

as well. Screw the cover into position, but not too

hard (0.2 kpm), or the valve may stop working.

Seawater ﬁlter. Cleaning

The seawater ﬁlter is an accessory. Screw off cover

(1) and remove seal plate (2). Lift out and clean the

insert (3).

IMPORTANT! If the boat is used in water that

has a lot of contaminants, seaweed etc. the ﬁlter

must be checked more frequently than indicated

in the maintenance schedule. Otherwise there

is a risk the ﬁlter will clog and the engine will

overheat.
