Description

The Sherwood 08000K Impeller Kit is a complete raw water pump service kit designed to restore proper cooling system performance in marine engines equipped with Sherwood 08000 series pump assemblies. This kit includes a precision-molded neoprene impeller along with sealing components and lubricant to ensure reliable water flow and long service life.

The impeller is responsible for circulating seawater through the engine cooling system. Over time, the flexible vanes can wear, harden, or crack, reducing efficiency and increasing the risk of overheating. Replacing the impeller at recommended intervals ensures consistent cooling performance and helps protect your engine from damage.

This kit is widely used across Sherwood pump-equipped marine engines, making it an essential maintenance item for dependable operation.
