Indmar 495001 Raw Water Pump Impeller Kit
Protect your engine from overheating and maintain dependable cooling performance with the Indmar 495001 Impeller Kit. Designed as a genuine OEM replacement, this raw water pump service kit restores proper water circulation and helps keep your inboard engine operating at the correct temperature under load.
The raw water impeller is one of the most important maintenance items on any marine engine. Over time, the flexible rubber vanes can wear down, 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 extend engine life and maintain reliable performance on the water.
Built to Indmar factory specifications, the 495001 kit provides the correct fit and sealing needed for dependable operation in harsh marine environments. Designed as a direct replacement for compatible Indmar raw water pumps, this kit makes routine maintenance straightforward and hassle-free.
