Impeller, Check and Change
WARNING!
Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
1 Remove the
seawater pump lid, and pull the impel-
ler out with water pump pliers.
2 Check the impeller. If any cracks or other defects
are visible, the impeller must be changed.
3 Lubricate the pump housing and the inside of the
lid with water-resistant grease (which is not aggres-
sive to rubber). The impeller will be easier to work
with if it is put in hot water prior to fitting.
4 Press the impeller in with a circular motion (clock-
wise). The shaft of the pump has an internal thread
(M8). Screw a stud into the end of the shaft and
press the impeller in using a washer and nut. Fit the
cover, using a new O-ring.
5 Open the sea cock.
IMPORTANT!
Always carry a spare impeller on board.
Seawater Filter, Check and Cleaning
WARNING!
Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
If the water where the boat is used has a lot of con-
taminants, seaweed, etc. the filter should be checked
more frequently
than stated in the maintenance sched-
ule, otherwise there is a risk that the filter may be
blocked resulting in engine overheating.
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, annu-
ally; 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.
