Good To Know

Q: Do I need to replace the bearings at the same time? A: Replacing shaft bearings and seals alongside the rotary shaft is commonly recommended since worn bearings can damage a new shaft. Inspect the pump housing for scoring before reassembly.

Q: Is this a genuine Sea-Doo part? A: This is an aftermarket rotary shaft assembly made for Sea-Doo watercraft and is not an original manufacturer product. Confirm your model and year match the listed fitment.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
