2013 Kawasaki Ultra 300X — Should You Buy One?

Typical asking price: $6,000–$10,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

A big, powerful supercharged Kawasaki that's now a used-only value — lots of horsepower for the money if the supercharger and engine were cared for. Older supercharged skis are exactly where neglect hides. The supercharger history and corrosion are the entire decision.

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.
