Product Overview

Replacement water pumps designed specifically for your GM, Ford or Chrysler based marine engine

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to OEM specifications.

The water pump is the heart of your inboard or I/O cooling system. Each Sierra pump is matched to the GM, Ford or Chrysler block used for your engine and is bidirectional and is compatible with conventional and reverse rotation engines. These marine water pumps have corrosion-resistant brass impellers, stainless steel backing plates and brass plugs. The pumps are also powder coated for additional protection.

Pumps include brass bi-directional impellers, brass plugs and fittings, carbon resin seal, all mounting gaskets, stainless steel seal cup and spring (not included with Model 1658400), stainless steel back plate (where required), and powder coating for maximum corrosion protection. Sierra water pumps are made from new castings and are not remanufactured.
