The impeller is molded from chloroprene rubber to resist abrasion and repeated flexing, while the brass hub and included seals are chosen for corrosion resistance in freshwater and light salt environments. It’s sold as a simple service kit with one impeller, one gasket, and two O-rings designed to match the original fit and function of Johnson, Yanmar, Sierra and Indmar service numbers.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this impeller kit improve my boat’s cooling system?\u003c\/h3\u003e\n\u003cp\u003eReplacing a worn impeller restores the pump’s ability to move the designed volume of water, reducing overheating risk and improving engine longevity.
