2026 Sea-Doo GTX 300 + iDF, iBR for sale near Mount Pleasant, TX Blue Abyss and Gulfstream Blue Touring Sea-Doo with 300 HP Rotax Power The 2026 Sea-Doo GTX 300 in Blue Abyss and Gulfstream Blue is built for riders who want premium touring comfort with serious performance on the water. With a 300 hp Rotax 1630 ACE engine, supercharged power, ST3 hull stability, direct access front storage, and room for 3 riders, this GTX 300 is made for long lake days, fast cruising, and comfortable weekends on the water. 300 HP Supercharged Rotax Performance The Rotax 1630 ACE 300 engine gives this GTX 300 the kind of power riders notice right away. With 300 horsepower, supercharged induction, and an external intercooler, it delivers quick acceleration and strong open-water performance while still fitting the smooth, planted feel that makes the GTX line such a popular touring Sea-Doo. The intelligent throttle control system includes Eco, Sport, Speed Regulator, and Slow Speed Mode, so the rider can adjust the machine to fit the conditions and the mood. Cruise comfortably, ease through no-wake areas, or bring out the full performance when the water opens up. ST3 Hull Touring Confidence The ST3 hull gives the GTX 300 a stable, predictable feel on the water. It is built for rough-water handling, easier boarding, and confident long-distance riding, while still giving the rider plenty of deck space to move around comfortably. With 3-rider capacity and a 600 lb weight capacity, this Sea-Doo is ready for solo rides, passengers, and full-day lake use. Direct Access Storage and Useful Features The direct access front storage system gives you 25.3 gallons of space that can be reached from a seated position by raising the handlebars. That makes it easier to reach lake-day essentials without climbing around the machine. There is also a watertight compartment with an integrated USB port to help keep a phone or small device protected and charged. Total storage capacity comes in at 26.1 gallons, giving you space for towels, sunscreen, dock items, and smaller gear for the day. Smart Features for Real Lake Use The intelligent debris-free pump system is a useful feature for riders who spend time around coves, shorelines, or other areas where debris can show up. If the intake gets clogged, the system can help clear it from the seat with the push of a button. The electronic brake and reverse system helps with braking, reverse, and low-speed control around docks, ramps, lifts, and trailers. That makes the GTX 300 easier to handle when the ride slows down and precision matters. 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.
