Description

The Volvo Penta Impeller Kit 22994993 is a complete raw water pump service kit designed to maintain proper cooling system performance in Volvo Penta marine diesel engines. This kit includes a precision-molded 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 commonly used on Volvo Penta D-series diesel engines, making it a key service item for modern inboard and IPS applications.
