2020 Sea-Doo RXP-X 300 — Should You Buy One?
Typical asking price: $11,000–$16,000. There is 1 high-severity known issue you need to know before handing over a check.
Kestrel Take
The muscle-car of skis — a supercharged 300hp Rotax in an aggressive hull built to carve. Thrilling and hard-used by nature. The supercharger service, wear ring, and hard-riding damage are the whole inspection. A supercharged ski with no service history is a real gamble.
What we checked
Not checked against public records
Personal watercraft fall to the Consumer Product Safety Commission rather than NHTSA. Its recall feed rarely names a specific model year, so we have not wired it in — matching on the brand alone would attach other people’s machines to this page. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
Known Issues for the 2020 Sea-Doo RXP-X 300
Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.
The Rotax supercharger needs periodic rebuilds (roughly every 100-200 hours). A neglected supercharger can shed its clutch washers into the engine — catastrophic. Verify the rebuild history.
Repair cost (estimate): $700-$3,000 (far more if it grenades the engine)
