2026 Sea-Doo GTR-X 300 iBR + Tech Package for sale in Mount Pleasant, TX Eclipse Black and Deep Marsala Sea-Doo Built for 300 HP Fun The 2026 Sea-Doo GTR-X 300 iBR + Tech Package in Eclipse Black and Deep Marsala is built for riders who want supercharged power, hard acceleration, race-inspired control, and premium technology in one performance watercraft. With a 300 hp Rotax 1630 ACE engine, launch control, Extended VTS, iBR, Ergolock racing seat, 7.8 inch color display, and premium Bluetooth audio, this GTR-X 300 is ready to bring serious power to the water. 300 HP Rotax Performance The Rotax 1630 ACE 300 engine is the heart of this Sea-Doo. With 300 horsepower, supercharged induction, an external intercooler, and a polished impeller, the GTR-X 300 delivers the kind of acceleration that makes every open-water run feel exciting. Launch Control helps this machine get moving quickly, while the Extended VTS system lets the rider fine-tune the ride. Eco, Sport, Speed Regulator, Slow Speed, and Launch Control modes give you more control over how the Sea-Doo responds throughout the day. Race-Inspired Handling and Control The GTR-X 300 uses the GTI hull with Polytec material for a ride that is playful, predictable, and confident. That combination helps the machine feel strong, responsive, and easy to enjoy whether you are making fast runs or working through tighter water. The Ergolock two-piece racing seat helps keep the rider connected to the machine during aggressive riding. Low-rise handlebars, the rear swim platform, and 3-rider capacity add the right mix of performance feel and real lake-day usability. Tech Package with Premium Audio The Tech Package adds a full-color 7.8 inch display with excellent visibility and useful ride information. The display shows key functions like speed, RPM, clock, Extended VTS, fuel autonomy, top speed, average speed, and vehicle hours. Bluetooth, USB, and smartphone app integration bring music, weather, navigation, and more into the ride. The 100W waterproof BRP Bluetooth Audio Premium system gives this GTR-X 300 the sound to match its performance. Storage, iBR, and Everyday Use Even with 300 hp on tap, this Sea-Doo is still practical for real days on the water. It gives you 40.3 gallons of total storage, including a 38 gallon front bin and a 2.3 gallon glove box for smaller items. The electronic iBR system helps with braking, reverse, and low-speed control around docks, ramps, and trailers. That makes the GTR-X 300 easier to handle when the ride slows down and the space gets tighter. Need a trailer too? Conroy Motorsports also has single and double PWC trailers available, so customers who need to haul one or two watercraft can handle the machine and trailer purchase at the same place.
