2021 Sea Doo RTX 300 X 3UP with trailer

This is a well-cared for 2021 Sea Doo RTX X 300 3Up (three persone). It is in perfect working condition and equipped with the 300hp Rotax engine which is a thrill ride through and through. 184 hours on the ski, comparable to the year made. Very reliable, serviced yearly with winterization and “de” winterization. It has a new battery as of May 2025. I have kept only up on lift and it has been flushed and rinsed off after every use. Dealer serviced, only normal exterior wear and tear. Seats have no tears, also equipped with Bluetooth premium sound system. Included are Sea Doo Cover, anchor, safety kit (required by coast guard) and mooring leads all around in addition to fixed points. The Jet Ski comes with a trailer that was built by the previous owner, DOT compliant but if you want to put a plate on it you will need to take bill of sale and register it at DMV. I keep on a boat lift so haven’t needed too.

There are 5 or so 2021 RTX 300s listed currently in Hampton Roads. They range in price from to 14,000. I’ve priced this one to sell because I bought a boat and need to put that on the lift! Not in a rush but would rather not have this great ski sit on a trailer unused. It’s summer! I’m not a dealer and I know all the scams so only serious buyers contact me. Must be picked up in Virginia Beach, cash or cashiers check only. Thank you!
