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.
Sierra water pump kits are designed to meet or exceed manufacturer specifications. Each kit is packaged to make service simple and includes everything needed to restore the water pump: eliminating 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.
