The Volvo Penta Impeller Kit 24139377 is a complete raw water pump service kit designed to maintain proper cooling system performance across a wide range of Volvo Penta marine engines. This kit includes a precision-molded impeller, sealing components, and installation 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 designed for engines using 6-bolt pump cover systems, making it a common service item across many Volvo Penta platforms.
