The Honda 78106-YH4-610 Impeller is a genuine OEM replacement built for the WX10 water pump. Sourced directly from Honda, this impeller is manufactured to the exact specifications of the original component, ensuring proper hydraulic performance from the moment it goes in. If your WX10 is showing signs of reduced flow, loss of prime, or sluggish output, this is the component to address first.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specifications for the WX10 water pump, so you know the blade profile, bore diameter, and clearances are exactly right
- Restored Pump Output — a worn or damaged impeller is the most common cause of reduced flow rate and loss of prime; replacing it brings the WX10 back to its rated capacity
- Direct-Fit Replacement — designed as a drop-in replacement for the WX10, with no adaptation or machining needed to install it
- Verify Your Serial Number — Honda supersedes parts at production breaks, so confirm your WX10 serial number against the fitment table before ordering
The impeller is the heart of the WX10's pumping system. Mounted on the pump shaft inside the volute housing, its spinning vanes draw water in at the center and fling it outward by centrifugal force, building the pressure and flow needed to move water through the discharge hose. When impeller vanes wear, erode, or crack — whether from abrasive debris, cavitation, or simple hours of use — the pump loses the ability to build pressure efficiently, resulting in a drop in flow rate or a failure to prime altogether. Replacing the impeller restores the pump's hydraulic geometry and gets the WX10 performing at its rated output again.
