The Sherwood 15000K Impeller Kit is a complete raw water pump service kit designed to maintain proper cooling system performance in marine engines equipped with Sherwood 15000 series pump assemblies. This kit includes a precision-molded neoprene impeller along with sealing components and hardware 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 helps restore cooling performance and protect your engine from damage.
This kit is commonly used across mid-range marine diesel and gasoline engines, making it a key maintenance item for dependable operation.
