The Jabsco 5616-0001 Neoprene Impeller Kit is a complete raw water pump service kit designed for Jabsco flexible impeller pumps. This kit includes a durable neoprene impeller along with the required gasket and sealing components to restore proper cooling water circulation and maintain reliable engine performance.
The impeller is a critical component responsible for drawing water through the cooling system. Over time, the flexible vanes can wear, harden, or crack, reducing efficiency and increasing the risk of overheating. Replacing the impeller at regular intervals ensures consistent water flow and protects your engine from costly damage.
Built to Jabsco OEM standards, this kit delivers dependable performance in both freshwater and saltwater applications.
