Yamaha Motors 6P2-W0078-00-00 Water Pump Repair Kit (viewing this product) Genuine OEM product	$107.95~~$134.95~~ In stock 5+ in stock	Best	Genuine Yamaha kit with OEM-spec fitment and a complete set of correctly matched components (metal-hub impeller, stainless insert cup and wear plate, composite gasket, and proper dowels/key). The flanged bolts with captive washers and individual Yamaha bagging indicate higher attention to corrosion control and assembly consistency. Insert cup is a Yamaha-supplied subcomponent marked Malaysia, but the overall kit quality and specification match OEM requirements.

EMP 46-46219 Water Pump Repair Kit Aftermarket product	$90.09~~$105.99~~ In stock Only 2 remaining	Better	Made in Italy with well-finished stainless wear components and clearly identified A2-70 (304 stainless) fasteners, suggesting strong corrosion resistance and good hardware quality. The impeller shows molded markings/date code and uses a brass hub, indicating deliberate manufacturing control. It remains a compatible (not identical) design to OEM due to the fully threaded bolts/tab-washer locking and a simpler fiber gasket compared with Yamaha’s composite gasket.

Recmar REC6P2-W0078-00 WATER PUMP KIT (REC6P2-W0078-00) Aftermarket product	$88.02~~$97.80~~ In stock Only 2 remaining	Good	Not a direct match to the OEM kit because it adds a replacement pump housing (embossed RECmar), which can be helpful if the original housing is worn or heat-damaged. However, the fasteners appear to use standard zinc plating and the gasket is a conventional fiber style rather than the OEM composite gasket and marine-coated hardware. Overall a serviceable kit with extra coverage, but corrosion resistance and OEM-spec detailing are a step down.

GLM Marine 12258 Water Pump Service Kit (12258) Aftermarket product	$94.15~~$117.69~~ In stock Only 2 remaining	Good	Functional replacement kit with the expected stainless cup/plate and a keyed impeller, but it uses a simpler blue fiber gasket and generic bolt/washer hardware rather than OEM-style flanged captive-washer bolts. Taiwan-origin rubber impellers are often less durable than OEM-grade compounds, which can matter in a critical cooling component. Best suited when you want a serviceable kit but are accepting some materials/spec differences versus Yamaha.

Peach Motors PM-6P2-W0078-00-00 Water Pump Repair Kit (No Housing) Aftermarket product	$116.95 In stock Only 2 remaining	Good	Includes the key wear items (impeller, stainless cup and plate, gasket, O-rings, dowels, key) and should install as a compatible rebuild set. Hardware and packaging are more basic than OEM (bulk-packed parts and different bolt head/finish), which can correlate with reduced corrosion protection and less controlled QC. A workable substitute, but not as close to OEM in fastener and sealing detail.
