Sea-Doo GTX 300 PWC For Sale

The Sea-Doo GTX 300 sits in Sea-Doo's touring category, the full-size, luxury-leaning end of the personal watercraft lineup that traces back to the original GTX introduced in 1992. It is built on the Rotax 1630 platform, offered with 170, 230 or 300 horsepower, and the GTX 300 is the supercharged, top-power version of the standard ski. The naturally aspirated 170 reaches around 58 mph and runs on 87 octane, while the supercharged 300 makes 300 horsepower and requires 91 octane premium fuel. The supercharger needs servicing roughly every 100 hours, a maintenance cost to factor in over the cheaper 170. Anyone shopping a Sea-Doo GTX 300 for sale is looking at the bracket where creature comforts and price both climb sharply over entry models.

The GTX 300 rides on the ST3 hull, a deep-V fiberglass design built to cut through open-water chop and hold a stable, predictable line. In the U.S. top speed is electronically limited to 68.5 mph like every PWC, so the figure that matters more is acceleration: the 300 reaches 60 mph in under four seconds. Out on the water in sport mode the 2021 GTX 300 Limited will run to roughly 125 km/h, a strong, immediate pull where the supercharger spins up above about 5,000 rpm. Fuel consumption stays reasonable when cruised in the 55–60 mph range; pushed hard near top speed it burns through fuel quickly, which is why fuel range is the practical limit on a long day.

Specs on the GTX 300 Limited put overall length at about 135.5 to 135.9 inches (3.45 m), width at 49.4 inches (1.25 m) and height around 44.8 to 44.9 inches. Dry weight is listed at 847 to 849 pounds (385 kg), with a rider capacity of three people and a weight capacity of 600 pounds. Fuel capacity grew to 70 liters (18.5 gallons) on recent model years, up from 60 liters on the 2018 GTX 300 Limited, which extends fuel range and reduces refueling stops at marinas where premium fuel runs expensive. Total storage is roughly 25.3 to 26.1 gallons.

A defining feature is the easy-access front storage: the entire bow and handlebar assembly lift up, letting a seated rider reach directly into the front cargo bin and its organizer without climbing over the bars. The trade-off is reduced capacity compared with a GTI's larger bin. Sea-Doo's intelligent debris-free (IDF) system is standard, spinning the impeller in reverse to flush weeds and debris from the intake without getting in the water, distinct from the intelligent brake and reverse (IBR) that drops a bucket to stop and back the ski. Intelligent throttle control runs throttle-by-wire, with a slow mode that holds speeds as low as 6 mph at its highest setting and a speed limiter that functions as cruise control, adjustable on the handlebar buttons.

The difference between the GTX 300 and the GTX 300 Limited is trim, not platform. The Limited adds the BRP premium audio system, a waterproof Bluetooth setup that adjusts volume with speed and links to Apple CarPlay or Android; a wide color display measuring 7 inches and, on the 2022 model, 7.8 inches; a built-in depth finder; the ergonomic UFI seat with added lumbar support for all three riders that detaches into a sun lounger; and a USB charging port with a waterproof glove-box compartment. A Limited typically ships with a dry bag, cover and full safety equipment including a fire extinguisher. The LinQ system lets you swap a cooler, fuel caddy or storage bin in seconds. The GTX 300 Limited has been offered across model years from 2018 through 2025 in colors such as sage green and liquid titanium, priced around $22,000 USD.

One point to weigh when buying: the ST3 hull developed a reputation for cracking at a weak spot in the bow on roughly 2021–2023 units, in some cases taking on water. Reinforcement is reported to have been added around the 2024 model year, with incidents dropping sharply on 2024, 2025 and 2026 skis, so the newest model years carry less risk on this front.
