2026 Sea-Doo GTI SE 170

The 2026 Sea-Doo GTI SE 170 is a 13-foot jet boat built on the largest platform in its class, designed for confident handling and reliable performance. It runs a Rotax 1630 ACE engine producing 170 horsepower—the most powerful naturally-aspirated engine in Sea-Doo's lineup—paired with strong fuel economy. The hull is constructed from Polytec material, which reduces weight, improves efficiency, and resists scratching better than traditional fiberglass.

This jet boat seats up to three passengers and features a large swim platform with LinQ attachment points for flexible customization. Storage space is generous at 40.3 gallons, with a dedicated watertight compartment for electronics. The intelligent Debris-Free Pump System allows riders to clear intake clogs with a simple button press without leaving the seat, reversing pump flow to remove debris on the water.

Comfort features include a 100-watt Bluetooth audio system fully integrated into the watercraft, letting you control music and volume wirelessly. The hull design balances stability with performance, delivering a predictable and easy-to-drive experience across varying water conditions.
