Water-pump impeller repair kit for MCM 4.5L MPI and 2000-and-newer MerCruiser V6/V8 305, 350 and 496 engines with the brass sea-water pump. Sierra designs the replacement around the specified OEM pump geometry and interchange references.

• Function: Circulates raw cooling water through the engine cooling system; a worn, hardened or damaged impeller can reduce water flow and cause overheating.

Verify the engine model, serial range, pump housing and original impeller number before installation. Inspect the housing, wear plate, key and gaskets at the same time; replace damaged companion parts rather than installing a new impeller into a worn pump.
