Yamaha 40HP, 50HP & P50 2-Stroke Water Pump Housing (Through 1994) | OEM Part 63D-44311-00-00

Maintain reliable cooling system performance with this Genuine Yamaha OEM Water Pump Housing (63D-44311-00-00). Designed for select Yamaha 40HP, 50HP, and P50 2-Stroke outboards through 1994, this housing encloses the water pump impeller and directs cooling water through the engine to help maintain proper operating temperatures and prevent overheating.

Over time, sand, debris, mineral deposits, corrosion, and normal wear can damage the housing's internal surfaces, potentially reducing water flow and increasing impeller wear. Replacing a worn or damaged water pump housing during water pump service helps restore proper cooling system performance and provides the correct OEM fit for your Yamaha outboard.
