2021 Yamaha GP1800R HO — Should You Buy One?

Typical asking price: $12,500–$16,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The naturally aspirated HO version of Yamaha's race-bred GP hull — the GP1800R HO delivers strong, reliable performance without a supercharger to service, which many buyers prefer for lower maintenance. It's a razor-handling ski that's a favorite for buoy racing and spirited riding. A low-hour, freshwater HO with clean compression is a superb, lower-maintenance performance ski; verify hours, pump, and flushing.

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.
