38 Raw water pump inspection
39 Pump cover removal
40 Impeller removal
The rubber impeller of the outboard water
pump is not proof against running dry.
If the water supply has been blocked, it may
be necessary to replace the impeller. Always
carry a spare impeller on board.
Inspection where appropriate changing is as
follows:
• Close the sea cock.
• Remove the cover of the pump by unscrew-
ing the screws out of the housing.
• Slide the impeller off of the shaft using a
waterpump plier.
• Mark the impeller to ensure correct re-in-
stallation if it is to be re-used. The impeller
must be installed in the same position as
removed.
