Kestrel Take
The reborn stand-up SuperJet, now with a four-stroke engine replacing the old two-stroke — more reliable and cleaner, if less raw. A specialist toy for experienced riders. Check for the hard falls and impacts these take, plus the usual salt-water and impeller wear.
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.
