45 Raw water pump inspection
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.
46 Pump cover removal
Inspection where appropriate changing is
as follows:
• Close the sea cock.
• Remove the cover of the pump by
unscrewing the screws out of the hous-
ing.
47 Impeller removal
• Slide the impeller off of the shaft using
a waterpump plier.
• Mark the impeller to ensure correct
re-installation if it is to be re-used. The
impeller must be installed in the same
position as removed.
