Does Yamaha water pump repair kit 6CE-W0078-02 fit a Yamaha F225XB?
I've got a Yamaha F225XB and need to replace the water pump impeller. Does Yamaha repair kit 6CE-W0078-02 fit, and is there anything else I should check before ordering?
Answer
Yes, Yamaha water pump repair kit 6CE-W0078-02 fits the standard Yamaha F225XB water pump, subject to confirming the engine serial number and any replacement gearcase. The F225XB belongs to Yamaha's 4.2-litre V6 Offshore family, so a listing that says only "F225" is not enough to confirm fit.
Check the engine identification
Find the identification plate on the transom bracket. Record the complete model designation, engine identification code and serial number so a Yamaha parts supplier can check the correct water-pump diagram and any superseded part numbers.
Yamaha has sold different 225 hp four-strokes. Pump components from earlier 3.3-litre F225 engines are not automatically interchangeable with those from 4.2-litre Offshore engines. F225XB identifies the engine more precisely than "225 Yamaha four-stroke".
- F225XB: identifies the relevant 4.2-litre Offshore model; the X denotes a nominal 25-inch shaft.
- Model suffix: the final B is part of the model designation, not a reliable calendar-year code.
- Replacement gearcase: if the lower unit has been changed, identify the unit fitted rather than relying entirely on the powerhead's plate.
Check the part number when searching: W0078 has two zeros after the W, not the letters "woo". A mistyped number can bring up misleading listings.
Check the kit contents
The 6CE prefix does not restrict the kit to engines with identification codes beginning 6CE. Yamaha shares service parts across several engines; the application listing establishes compatibility.
Ask what the exact kit supplied contains. A water-pump repair kit is not necessarily a complete pump assembly. Online photographs sometimes show a different package or an aftermarket equivalent.
Before paying, check whether the package includes:
- The rubber impeller.
- The pump wear plate and associated gaskets.
- The impeller drive key and any specified seals or O-rings.
- The stainless-steel cup or liner, if required for your repair.
Do not assume the outer pump housing is included. If a supplier offers a later suffix as a replacement for 6CE-W0078-02, ask them to confirm the supersession against your engine identification. A higher suffix does not automatically mean the parts are interchangeable.
