Yamaha XTO 425/450 4-Stroke Water Pump Housing – 6GR-44311-00-00 | OEM

Yamaha XTO 425/450 4-Stroke Water Pump Housing – 6GR-44311-00-00

Maintain proper cooling-system performance with the Genuine Yamaha OEM Water Pump Housing 6GR-44311-00-00. This housing encloses the water pump impeller and directs cooling water through the engine on select Yamaha XTO Offshore 425 and 450 outboards.

Sand, debris, mineral deposits, corrosion, and normal wear can damage the housing's inner surfaces over time, reducing water flow and shortening impeller life. Replacing a worn housing during water pump service helps restore cooling performance and protect the engine from overheating.

• XTO 425
