2025 Sea-Doo GTX 300

The 2025 Sea-Doo GTX 300 is a 3-passenger personal watercraft powered by a supercharged Rotax 1630 ACE engine producing 300 horsepower. Built on a fiberglass ST3 hull, it combines strong acceleration with stable handling and control. The design prioritizes both performance and everyday usability for recreational riding, cruising, and watersports.

The GTX 300 accommodates three riders with touring-focused seating designed for comfort on extended outings. A large swim platform with integrated LinQ attachment points serves as a base for accessories and water activities. Storage capacity totals 26.1 gallons across direct-access front compartments and other lockers, with an 18.5-gallon fuel tank supporting longer days on the water.

Key technologies include iBR intelligent brake and reverse for simplified low-speed maneuvering and docking, and iDF debris-clearing pump technology for operation in weedy or debris-prone areas. The boat offers three ride modes—Sport, ECO, and Slow—plus a VTS trim system for adjusting attitude on the water. A closed-loop cooling system manages thermal performance. The dry weight is 807 pounds, with overall dimensions of 135.9 inches in length and 49.2 inches in beam.
