2026 Sea-Doo GTR-X 300

The 2026 Sea-Doo GTR-X 300 is a high-performance personal watercraft powered by a supercharged Rotax 1630 ACE 300 hp engine. Built on the GTI hull with Polytec construction, it seats three riders and combines responsive acceleration with playful, predictable handling. The jet features electronic iBR intelligent brake and reverse for precision control, an Extended Variable Trim System, and a closed-loop cooling setup with electronic fuel injection.

The riding position emphasizes performance and connection. An Ergolock two-piece racing seat, low-rise racing handlebar, and double-angled footwell wedges with premium carpeting create an athletic platform for spirited riding. A stainless polished impeller and 18.5-gallon fuel capacity support extended outings, while generous storage includes a large front compartment, watertight phone storage, and a swim platform with tow hook.

Entertainment and convenience features include a factory-installed BRP Audio Premium System with Bluetooth connectivity, a 7.8-inch full-color display, and a USB port. The LinQ attachment system provides accessory flexibility. At 813 pounds dry weight with a 600-pound payload capacity, the GTR-X 300 balances performance hardware with practical day-on-the-water capability for solo runs, recreational cruising, and passenger outings.
