Sierra Water Pump Housing for Yamaha Outboards

Sierra water pump housings are replacement cooling system parts for Yamaha outboard engines. The housing holds the impeller and directs raw water through the engine's cooling circuit. A worn or damaged housing can reduce water flow and lead to overheating, so replacing it helps restore cooling performance.

Key Features:

• Designed as a direct replacement for the original Yamaha outboard water pump housing
• Made to meet or exceed the original equipment part it replaces
• Interchanges with Yamaha OEM and Mallory part numbers (listed on each individual item)
• Works with Sierra water pump kits and impellers for a complete cooling system rebuild
• Sold as a replacement part for routine maintenance or repair of Yamaha outboard water pumps
