Good To Know

Q: When should I replace the impeller in a 25hp outboard? A: Outboard impellers typically need replacement every few seasons or once coolant flow weakens. Check the existing impeller for cracks or missing blades before reinstalling the pump.

Q: Can I install this repair kit myself? A: Most boat owners can install it using basic hand tools and the service manual. Make sure the water pump housing and wear plate are undamaged before assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
