Yamaha - Housing, Impeller 2 - 6FU-51317-00-00

Overview

The Yamaha 6FU-51317-00-00 Housing, Impeller 2 is a genuine OEM component designed to support the water pump assembly and ensure efficient circulation of cooling water through the engine. The impeller housing forms the chamber where the water pump impeller rotates, allowing it to create the pressure needed to move water through the engine’s cooling system.

A properly functioning housing helps maintain optimal water pump performance by providing the correct internal shape and clearance for the impeller. Over time, debris, sand, or normal wear can cause grooves or damage inside the housing, reducing the efficiency of the water pump. Replacing worn pump housing components helps restore proper water flow and protects the engine from overheating.

FAQ

Q: What does an impeller housing do in an outboard motor?
A: It forms the chamber around the impeller, allowing it to generate pressure and move cooling water through the engine.

Q: When should the impeller housing be replaced?
A: During water pump service if the internal surfaces show grooves, scoring, or excessive wear.

Q: Can a worn housing affect engine cooling?
A: Yes. Damage inside the housing can reduce water pump efficiency and decrease cooling water flow.

Q: Is this a genuine Yamaha part?
A: Yes. The 6FU-51317-00-00 is a genuine Yamaha OEM water pump component.

Q: Is this typically replaced during impeller service?
A: It is usually inspected during impeller replacement and replaced if wear or damage is found.
