Quick Take
The 2026 Sea-Doo GTI SE 170 is a three-rider Recreation-class personal watercraft powered by Sea-Doo’s 170-horsepower Rotax 1630 ACE engine, starting at $13,899 MSRP. It measures 130.7 inches long and 49.2 inches wide, weighs 741 pounds dry (761 with the optional sound system), carries 40.3 gallons of storage and 18.5 gallons of fuel, and now includes iDF debris clearing as standard for 2026. It’s best for families who want one do-it-all ski with stability, storage, and real performance without paying for a supercharged engine.
What Is The 2026 Sea-Doo GTI SE 170?
The GTI SE 170 is the high-output trim of Sea-Doo’s GTI SE line, which sits in the Recreation category on BRP’s official lineup—above the entry GTI and Spark Rec-Lite models and below the GTX touring skis. Sea-Doo markets it specifically to “families craving performance,” pairing a Polytec GTI hull with a naturally aspirated 170-hp Rotax engine and the brand’s full comfort and storage package. The 2026 model year introduces iDF (Intelligent Debris-Free) as standard equipment across the GTI SE trim, a change Sea-Doo confirmed directly on its own channels.
How Much Does It Cost?
Starting MSRP is $13,899 for the base GTI SE 170 in the standard color, with transportation, preparation, and dealer fees not included. The commonly stocked Tech Package + Audio + iDF + iBR build retails around $14,699 at dealers. BRP’s one-year limited warranty is standard, and extended B.E.S.T. coverage is available at the point of sale.
What’s New For 2026?
The biggest change is that iDF is now standard on the GTI SE—previously an optional upgrade—along with a new Eclipse Black/Laguna Green colorway to complement the returning Teal Blue/Manta Green. iDF uses a reversing impeller activated by a handlebar button to clear weeds and light debris from the jet pump without the rider getting in the water. The optional factory-installed BRP Premium Audio (100-watt waterproof Bluetooth) carries over and adds roughly 20 pounds to dry weight when equipped.
What Are The Verified Specs?
How Does It Ride On The Water?
The GTI hull is engineered for stability at rest and predictable handling in chop, which is why dealers consistently position it as the family-friendly Sea-Doo that still delivers spirited performance with 170 hp on tap. The Rotax 1630 ACE delivers smooth, linear acceleration suited to towing tubes and wakeboards, cruising, and open-water riding; it is naturally aspirated, so there is no supercharger maintenance schedule to worry about. iBR (Intelligent Brake & Reverse) and Variable Trim System come standard, giving riders on-the-fly control over hole shot, top-end attitude, and low-speed maneuvering at the dock.
Does It Handle Saltwater?
Sea-Doo personal watercraft use a closed-loop cooling system that keeps saltwater out of the engine block, a meaningful corrosion advantage for coastal riders compared to Yamaha’s open-loop architecture. The Polytec hull is also more scratch-and impact-resistant than traditional fiberglass, which matters for owners who beach-launch or ride in rocky coves. Post-ride freshwater flushing is still recommended, but the maintenance overhead for saltwater use is lower than on an open-loop platform.
Is The GTI SE 170 Worth The Upgrade Over The 130?
The 170-hp version costs $600 more than the 130-hp GTI SE and shares the same hull, storage, capacity, and electronics—you are paying strictly for the engine tune. If you primarily tow water toys, ride open water, or carry two or three passengers regularly, the 170 is worth the upgrade for the improved hole shot and mid-range pull. If you ride mostly no-wake zones, tight coves, or solo cruising, the 130-hp version covers that use case at a lower price.

The Verdict
Buy the 2026 Sea-Doo GTI SE 170 if you want the most versatile ski in Sea-Doo’s Recreation class and you value three-rider stability, 40 gallons of storage, and standard iDF enough to pay a small premium over the 130-hp version. Choose the GTI SE 130 at $13,299 if you ride mostly no-wake or tight-cove conditions where the extra horsepower won’t be used. Step up to a GTX at $15,949 only if you want a plusher touring seat and premium finishes—the mechanical core is broadly similar until you reach supercharged territory.
