2021 Sea-Doo RXT®-X® 300 with Sound System in Midnight Purple

The Ultimate Performance Watercraft

Its revolutionary lighter platform, combined with the Ergolock System, maximizes control in any condition, making the RXT-X the new benchmark for rough water performance. With the 300-hp engine, 60 mph (96 km/h) is just a few seconds away.  Your Sea-Doo Life starts at Centre PowerSports & Marine located Sauk Centre, MN located between Alexandria, MN and St. Cloud, MN.

  • Modular ergolock seat:  The narrow seat places your knees closer together in a natural riding position, while the stepped seat design provides more lateral support and stability for you and your passengers. Plus, the removable rear seat gives you even more space for hanging out, sunbathing or a face-to-face picnic.
  • Large swim platform:  The first watercraft to hang out on the water with the largest swim platform in the industry. Flat, stable and comfortable, it is ideal for boarding, lounging, and prepping for tow sports. Create even more space by removing the rear seat.
  • At Rest. At Speed. Always Steady: Whether you’re at high speeds pounding rough offshore waters, at rest hanging out in a cove or you’re simply boarding from the side, the wider hull offers industry leading stability thanks to a lower center of gravity and improved hull design.
  • Rotax 1630 ACE engine:  The most powerful engine on a Sea-Doo, ever!  Supercharged with an external intercooler, the advanced combustion efficiency (ACE) technology delivers high efficiency and amazing acceleration. This is the most powerful engine on a Sea-Doo producing a thrilling 300-hp.
  • Direct access front storage: All your gear is now within arm’s reach. The industry’s first direct-access front storage opens by simply raising the handlebar assembly. No standing required. It’s the smartest water-resistant storage we’ve ever built into a watercraft, offering room for your next adventure.
  • Rear cargo linq system:  Extra rear storage is now possible with the secure quick-attach linq system. It allows to easily snap a fuel caddy, a bag, a cooler and more, to the back of your watercraft using two convenient, integrated attachment points.
  • Bluetooth audio-premium system:  The industry’s first fully-integrated waterproof audio system will keep the fun going anywhere you go, with 100 watts of total system power, fully-waterproof performance, bluetooth connectivity, and external playback controls to ensure the perfect song is always on deck.
  • Ergolock system with modular seat:  The narrow racing seat places your knees closer together to hold on tighter while improving the transition into standup riding. Plus, the removable rear seat gives you even more space for hanging out on the rear platform, sunbathing or a face-to-face picnic.
