2026 Sea-Doo GTX 300

The 2026 Sea-Doo GTX 300 is a 11-foot jet boat powered by a single Rotax 1630 ACE engine with 300 horsepower. Built on the ST3 hull platform, this boat combines stable, predictable handling with confident offshore performance and easy boarding thanks to its spacious deck layout.

The GTX 300 accommodates up to three passengers and features removable seating with emphasis on comfort. A large swim platform includes LinQ attachment points for gear mounting. The front storage area provides 25.3 gallons of space, accessible from a seated position with a watertight compartment and integrated USB port to keep devices secure and charged.

Sea-Doo's Intelligent Debris-Free (iDF) pump system sets this model apart—a button-push reversal clears intake clogs without leaving the seat. The 300 hp Rotax engine delivers both quick acceleration and fuel efficiency, while optional Bluetooth audio is available to enhance the ride experience.
