2026 Sea-Doo GTI

The 2026 Sea-Doo GTI is a three-person jet ski built on a modified V hull. It measures 10 feet 9 inches in length and weighs 741 pounds dry. Power comes from a single liquid-cooled, in-line four-stroke engine with 1630 cc displacement and electric starting. The fuel tank holds 18.5 gallons, and additional storage capacity reaches 40.3 gallons. An axial flow pump and direct drive transmission move the watercraft through the water.

Standard instrumentation includes a speedometer, tachometer, and mirrors. The GTI accommodates up to three riders and is designed for responsive handling in varied water conditions typical of recreational jet ski use.
