2021 Sea-Doo GTX 170

The 2021 Sea-Doo GTX 170 is a fiberglass jet boat powered by a single 170 hp Rotax engine equipped with Advanced Combustion Efficiency technology. At 11.3 feet long with a 4.08-foot beam, it combines compact dimensions with a spacious on-water footprint. The ST3 hull is engineered for stability and predictable handling in rough conditions, while the large swim platform—the largest in its class—provides flat, stable space for lounging and watersports. The platform includes LinQ attachment points for configurable accessories.

The boat accommodates up to three passengers and centers on comfort and convenience. The stepped Ergolock seat narrows at the front for natural riding posture and widens toward the rear; the rear section can be removed for additional lounge space or to create a two-person table. Direct-access front storage holds 25.3 gallons and is reachable from the seated position with a simple handlebars raise.

Standard technology includes the iBR intelligent brake and reverse system, which allows riders to engage forward, neutral, and reverse with both hands on the bars for stable low-speed maneuvering. The iDF intelligent debris-free pump system lets riders clear intake clogs from their seat with a button press. Variable Trim System handles on the handlebars enable fine-tuned trim adjustments for different water conditions and passenger loads. The boat carries a 100W premium Bluetooth audio system with waterproof speakers and a remote pad.

The engine has logged 78 hours and has recently undergone annual service.
