The Honda 78106-YF2-505 Impeller is a genuine OEM component designed for the WX15 water pump. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring correct clearances and flow characteristics within the pump's volute. This impeller is the right choice for restoring full pumping capacity to the WX15 — confirm your unit's serial number against the fitment table before ordering to ensure this is the correct part for your machine.
Key Features
- Genuine OEM Flow Performance — manufactured by Honda to the original impeller profile, delivering the correct vane geometry and running clearance for proper water displacement in the WX15 pump
- Direct OEM Replacement — an exact-fit Honda part that drops into the pump housing without modification, restoring the pump to its original operating condition
- Fits WX15 Water Pumps — sourced directly from Honda's parts catalogue for the WX15 lightweight centrifugal water pump; verify your serial number against the fitment table to confirm applicability
- Wear-Critical Component — a worn or damaged impeller reduces flow rate and pressure output noticeably; replacing it with a genuine Honda part brings pump performance back to specification
The impeller is the rotating core of a centrifugal water pump. Driven by the engine, it spins at high speed inside the volute housing, using centrifugal force to draw water in through the inlet and push it out under pressure through the discharge port. Over time the vanes wear or become damaged by debris, reducing the pump's output — a degraded impeller will move less water, build less pressure, and in severe cases cause the pump to lose its prime entirely. Replacing a worn impeller with a genuine Honda part restores the WX15 to its original flow and pressure performance.
