Maintenance. Seawater system
Impeller. Check/change
WARNING! Risk of water entry. Close the sea
cock before doing any work on the seawater
system.
1. Remove the seawater pump lid, and pull the im-
peller 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 ag-
gressive 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 (coun-
ter clockwise). 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. Inspection/cleaning
The seawater filter is optional equipment.
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 sched-
ule. There is otherwise a risk that the filter would be
blocked, which would make the engine overheat.
WARNING! Risk of water entry. Close the sea-
water cock before doing any work on the seawa-
ter system.
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 O-ring. Change as necessary.
5. Open the sea cock and check carefully that no
leakage occurs.
