The Honda 78106-YH5-610 Impeller is a genuine OEM replacement built for the WX15 water pump. As the original Honda-sourced component, this impeller is manufactured to the same specifications as the part that left the factory, ensuring correct clearances inside the pump volute for proper water flow and pressure. This is the right part for WX15 owners who want a straightforward, verified replacement backed by Honda's own parts program.
Key Features
- Genuine OEM Impeller — sourced directly from Honda, this impeller is built to the exact geometry required for correct flow rate and discharge pressure in the WX15 pump
- Direct-Fit Replacement — designed as a drop-in replacement for the WX15 water pump; no improvising or adapting required to restore the pump to original condition
- Restores Pumping Performance — a worn or damaged impeller causes a noticeable drop in flow and pressure; replacing it with part number 78106-YH5-610 brings the pump back to its rated output
- Verify Your Serial Number — Honda updates parts at production breaks, so confirm your WX15 serial number against the fitment table before ordering to ensure this is the correct impeller for your unit
The impeller is the rotating core of a centrifugal water pump. As it spins at high speed inside the pump volute, its curved vanes fling water outward by centrifugal force, converting engine power into flow and pressure at the discharge port. When an impeller wears, chips, or erodes — whether from abrasive sediment, cavitation, or simply age — the pump loses the ability to move water efficiently, showing up as reduced flow, weak discharge pressure, or a complete loss of prime. Replacing the impeller with the correct Honda OEM part restores the tight running clearances that efficient pumping depends on.
