Seawater filter. Check/Clean
The seawater filter is an accessory and is available in
two models.
If the water the boat is in is severely polluted, con-
tains large amounts of seaweed, etc., the filter must
be checked more often than is specified in the main-
tenance schedule. The filter can otherwise become
clogged and the engine overheat.
