Seawater Filter, Check and Cleaning
The seawater filter is optional equipment. Volvo Penta
offers two different seawater filters.
If the water where the boat is operated contains a lot
of contamination, weed etc., check the filter more
frequently than specified in the maintenance schedule.
There is otherwise a risk that the filter would be
blocked, which would make the engine overheat.
WARNING!
Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
1 Close the sea cock.
2 Unscrew the cover by hand counter clockwise (1).
3 Lift out the insert (2) and clean it.
4 If the glass vessel (3) needs cleaning from e.g.
algae fouling, this must be done from the top with
the aid of a suitable brush; use soapy water as
required. The glass vessel must (3) not be
removed!
5 Screw the cover back on (1) by hand. The cover
threads should be brushed with silicone-based
water-proof grease, e.g. VP part # 828250,
annually; this will ensure that the cover does not
seize on removal.
Mineral oil based grease may not be used.
6 Open the sea cock and check for leaks.
1 Close the sea cock.
2 Remove the lid (1) and lift up the insert.
3 Clean the insert and the housing (2).
4 Install the components as in the illustration. Check
the seals. Change as necessary.
5 Open the sea cock and check carefully that no
leakage occurs.
