Service the water pump and make the most of the boating season

Starting the season with a freshly serviced water pump will pay dividends later when the sun is out and the fish are biting. A water pump impeller that has sat idle for the winter or one that is worn from year-round use can reduce cooling water flow and cause an engine to overheat. Servicing the water pump annually (at the least) will keep you on the water longer.

For 50 years Sierra has been assembling water pump kits designed to meet or exceed manufacturer specifications. Each kit includes everything needed to restore water pump function and eliminates the hassle of searching for and sourcing the individual parts. Boaters and technicians can be assured Sierra parts will fit right the first time and restore function to OEM or better standards.

Key Features

  • Engineered to meet or exceed OEM specifications
  • Pre-assembled kit eliminates extra time spent sourcing individual parts
  • Kit includes; Impeller, wear plate, upper and lower base and pump gaskets, O-rings, and rubber washer
  • Fits Mercury applications
