The Honda 78105-YG1-003 Outlet is a genuine OEM component designed for WT20 and WT30 water pumps. Sourced directly from Honda, this part is manufactured to the same standards as the original, ensuring it seats and seals exactly as intended. This outlet is listed for both the WT20 and WT30 water pumps — confirm the part number 78105-YG1-003 against your unit's parts diagram before ordering, as configuration details can vary across serial ranges.
Key Features
- Genuine Honda OEM Quality — made to the same specification as the original outlet, so flow path geometry.
- Direct OEM Replacement — drops into position on WT20 and WT30 pumps the way the factory part did, with no reworking of the discharge side required
- Serial-Range Awareness — Honda updates parts at production breaks, so cross-check the serial number on your pump against the fitment table to confirm this is the correct outlet for your unit
- Restored Discharge Performance — a damaged or degraded outlet can disrupt flow at the discharge port; replacing it with this genuine part helps the pump move water at its intended volume and pressure
The outlet is the discharge fitting through which pressurized water exits the pump and enters the attached hose or piping. On centrifugal water pumps like the WT20 and WT30, the impeller spins water outward into the volute, and the outlet channels that flow out of the pump body under pressure. A cracked, stripped, or otherwise damaged outlet reduces flow efficiency, causes leaks at the discharge connection, and can bring a pumping job to a halt. Replacing a worn outlet restores the integrity of the discharge path and gets the pump delivering water the way it should.
