Genuine Tohatsu Water Pump Impeller for BFT115 / BFT150

Check before ordering
- Confirm the complete Tohatsu BFT or Honda BF engine model.
- Check the engine serial number against the manufacturer parts catalogue.
- Match HZW1-19210-B04 or Honda 19210-ZW1-B04 to the required impeller.
- Inspect the pump housing, liner, key, O-ring and gaskets; order a complete kit if those parts also require replacement.
Frequently asked questions
Does this fit small Tohatsu MFS2.5–MFS5 engines?
No. This impeller belongs to selected BFT115/BFT150 and compatible Honda BF75–BF150 applications.
Is this a complete water-pump kit?
No. The listing is for one genuine impeller only. Housing, liner, key, seals and gaskets are separate parts.
Can it be used on a Honda outboard?
Yes, on selected Honda models that specify 19210-ZW1-B04. Confirm the exact model and serial range first.
When should the impeller be replaced?
Follow the engine service schedule and replace it sooner if cooling-water flow weakens, the engine has been run dry or the impeller shows cracking, deformation or missing vanes.
