2021 Yamaha EX Sport — Should You Buy One?

Typical asking price: $7,000–$9,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The value entry into Yamaha's lineup — the EX Sport uses the reliable, naturally aspirated TR-1 engine (no supercharger to service) in a light, friendly, easy-to-tow hull that's perfect for new riders and families. It's not fast, but it's dependable and cheap to run. A low-hour, freshwater EX Sport with clean compression is one of the smartest first-ski buys; verify hours, flushing, and pump condition.

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.
