SECTION SEVEN
Raw Water Pump – Replace the impeller if it is worn or each year.
Since you must remove the impeller to inspect it, it is good practice
to replace the impeller every year as a routine. Be sure there are
no impeller parts lodged in the hoses or elsewhere in the system
as they will eventually move to a different place and restrict water
flow. The raw water pump impeller should be replaced every year
or whenever it is found to be worn or have damaged blades. Be
sure to reassemble with the proper gaskets.
