2021 Sea-Doo GTI SE 170 — Should You Buy One?

Typical asking price: $9,000–$13,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The best-selling family runabout with the naturally aspirated 1630cc Rotax — no supercharger, stable, and easy to ride. One of the most sensible used PWCs. Sea-Doo's brake-and-reverse system adds convenience and a few more parts to check. Verify the wear ring and salt history.

Boats and personal watercraft are not in NHTSA’s database — that is the Coast Guard, which publishes recalls but no owner-complaint record.
