Ilmor 50H-0170 Raw Water Pump Impeller Kit
Keep your engine running cool and protected with the Ilmor 50H-0170 Impeller Kit, a genuine OEM raw water pump service kit designed for modern Ilmor marine engines. Built to factory specifications, this kit restores proper water circulation and helps prevent overheating during long days on the water.
The raw water impeller is one of the most important maintenance items on any inboard engine. Over time, the rubber vanes can wear, harden, or crack from heat and continuous use, reducing cooling efficiency and increasing the risk of engine damage. Replacing the impeller at recommended service intervals helps maintain proper operating temperature and dependable engine performance.
The 50H-0170 kit is manufactured using high-quality marine-grade materials and includes the impeller and sealing O-ring needed for installation. Designed as a direct replacement, it provides the precise fit and reliability expected from OEM Ilmor components.
