The Honda 78106-955-000 Impeller is a genuine OEM component designed for the WA30 water pump. As a direct Honda OEM part, it is manufactured to the same standards as the original, ensuring the pump restores its rated flow capacity and pressure. Confirm your unit's serial number against the fitment table before ordering to ensure this is the correct impeller for your WA30.
Key Features
- Genuine OEM Flow Performance — manufactured by Honda to match the original impeller's vane geometry and dimensions, restoring the WA30's designed pumping capacity rather than approximating it.
- Direct OEM Replacement — replaces the original impeller with a part sourced directly from Honda, so installation drops straight into the existing pump housing with no fitting adjustments.
- Built for the WA30 Water Pump — this part is specified for the WA30, and verifying your serial number against the fitment table is the surest way to confirm it matches your unit.
- Restore Pumping Efficiency — a worn or damaged impeller causes a sharp drop in flow rate and discharge pressure; replacing it with this genuine part brings the pump back to full working output.
The impeller is the rotating core of a centrifugal water pump. Spinning at engine speed inside the pump volute, its curved vanes fling water outward by centrifugal force, building the pressure that drives flow through the discharge hose. When the impeller wears, cracks, or erodes — often from abrasive debris in the water — the pump loses flow rate and discharge head, and in severe cases moves no water at all. Replacing the impeller is the primary repair for a WA30 that runs but pumps poorly.
