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
impeller out with universal impeller puller.
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
aggressive 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 (counter
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.
NOTICE! Always carry a spare impeller on board.
