Water Pumps
The water pump is the heart of your inboard or I/O cooling system. Pumps are matched to the GM, Ford or Chrysler block used to make your engine. All Sierra pumps are bidirectional and can be installed on 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. Includes mounting gasket.

Pumps include brass bi-directional impellers, brass plugs and fittings, carbon resin seal, all mounting gaskets, stainless steel seal cup and spring, 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.
