2021 Yamaha GP1800R SVHO — Should You Buy One?

Typical asking price: $12,000–$17,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The performance benchmark — a supercharged 1.8L in a race-bred hull, and the ski to beat in stock-class competition. Yamaha's supercharger is more robust than some, but it's still a supercharged, hard-ridden machine. Verify supercharger and hours, plus hard-use damage.

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.
