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

No public record to reconcile against

We don't yet have a public record to check this one against. Boats and personal watercraft are not in NHTSA’s database — that is the Coast Guard, which publishes recalls but no owner-complaint record. 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.

Supercharger rebuild intervalHigh — wallet impact

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)

Source: not yet checked against public records.

Repair cost (estimate): $150-$600
