Sierra Impeller 18-45003, Replaces 47-F433065, Fits Force 35/45/55 hp Outboards (1974-80)

The Sierra 18-45003 is a water pump impeller built as a direct replacement for the impeller used in the cooling systems of Force outboard engines. The impeller is the rotating component inside the outboard's water pump housing that draws raw water in and circulates it through the powerhead to keep the engine running at safe operating temperatures. Made of metal, it is designed to seat and perform to the same fit as the original equipment part it replaces.

This impeller is a match for Force 35, 45, and 55 hp outboards (1974-80) and is a direct equivalent to OEM number 47-F433065, so it installs in place of the original without modification. The package includes one impeller.
