2021 Sea-Doo GTR 230 — Should You Buy One?

Typical asking price: $11,000–$14,500. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The value performance Sea-Doo — the GTR 230 puts a supercharged 230-hp Rotax in a comfortable, stable recreation-style hull, giving you real speed at a lower price than the RXP/RXT-X models. Same critical supercharger-rebuild watch-item as any supercharged Sea-Doo. A documented, freshwater GTR 230 with a rebuilt supercharger and clean compression is a lot of performance ski for the money; verify the supercharger history.
