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
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.
