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.

Known Issues for the 2020 Sea-Doo RXP-X 300

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
