Sea-Doo GTI 170 PWC For Sale

The Sea-Doo GTI SE 170 is the upper trim of Sea-Doo's entry-level full-size recreation lineup, sitting above the base GTI and built on the same redesigned platform introduced for 2020. Power comes from the Rotax 1630 ACE, a naturally aspirated 1630cc three-cylinder that runs on standard 87 octane. The GTI is offered only in naturally aspirated form, with no supercharger option, which keeps fuel and maintenance costs down. The "170" designation refers to the 170-horsepower tune; the same engine is also sold in a 130-horsepower version, and on the SE the jump to 170 is roughly a $600 factory option. The base GTI is currently available only in 130 horsepower, so a true 170 requires the SE.

For anyone shopping the Sea-Doo GTI SE 170 for sale and comparing specs, the numbers are concrete. A 2020 GTI SE 170 weighs 739 pounds, about 51 pounds lighter than the previous 790-pound GTI SE 155. Acceleration to 50 mph takes 5.2 seconds, a 20% improvement over the older 155. Top speed measured out at 55 mph at 7,700 RPM. The 170-horsepower Rotax is described as the most powerful naturally aspirated engine Rotax has produced. The hull is Polytec 2.0, roughly double the thickness of earlier hulls at about half an inch versus a quarter inch, with fiberglass inner stringers for added stiffness. The shorter, lighter Polytec hull makes the ski playful and easy to carve and slide, while still tracking predictably through chop rather than bouncing like a smaller craft.

The helm uses a 4.5-inch digital display that can be set with an orange backlight, reading speed, RPM, fuel, trim and gear position. The GTI SE 170 includes IBR, Sea-Doo's intelligent brake and reverse system, and for 2026 the SE adds IDF, the intelligent debris-free system that spins the impeller in reverse to clear seaweed from the pump without getting in the water. VTS variable trim is controlled from the left handlebar pad, alongside slow mode, a speed regulator that caps top speed and lets a new rider idle through marinas at presets up to about 9 mph. Riding modes include Sport, Eco and Eco off.

Storage and deck layout are strong points. The bow compartment holds 42.5 gallons, with a 2.3-gallon glovebox under the handlebars that includes a watertight phone case; the rubber plug can be swapped for a USB charging port. The rear deck uses the LinQ modular system on 16-inch on-center mounts, so accessories like the 4.2-gallon cooler, fuel caddy, retractable ski pylon or the larger 13.5-gallon Fish Pro cooler can be added. Removing the rear seat reveals an extended platform 36% larger than the prior model. Other touches include molded dock-line loops below the handlebars, bow hand grips for beaching, and a metal tow eye above the bond rail.

Among the SE 170 accessories, the BRP premium audio system is a 100-watt Bluetooth-controlled unit best ordered from the factory, available as part of an $800 tech package that bundles the audio with IBR and IDF; the control pad sits tucked tight against the fairing. The reboarding step is standard on the SE but a roughly $265 option on the base GTI, which makes water re-entry much easier. The SE supports towing wakeboarders, skiers and tubes, and pulls two single tubes without trouble, though it has no dedicated ski mode, so the driver must feather the throttle to hold a steady tow speed.

On price, the 2020 GTI SE 170 carried an MSRP of $11,399 before the premium sound system, and the SE has more recently been listed around $13,300 against roughly $12,100 for the base GTI. That positioned it several hundred dollars under the Yamaha VX Cruiser HO it competes with. Color choices have included Ice Metal with Orange Crush and Beach Blue Metallic with Lava Grey. Across the 2021, 2022, 2024 and 2025 model years the GTI SE 170 has remained closely based on the 2020 redesign, so used examples share the same Polytec 2.0 hull, Rotax 1630 ACE engine and core feature set.
