2018 Kawasaki STX-15F — Should You Buy One?

Typical asking price: $6,000–$9,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A long-running, no-nonsense Kawasaki recreation ski with a naturally aspirated 1498cc four — strong, simple, and cheap for the power. Kawasaki's dealer network is thinner than Yamaha's or Sea-Doo's, so verify local support. Then it's the usual hours, flushing, and pump check.

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.
