The Sea-Doo GTX is a high-end personal watercraft, sold with an entry-level 170 hp engine up to a supercharged 300 hp motor that makes it one of the most powerful on the market. Everything about the GTX 170, 230, and 300 is the same except for the electronic power limiter (essentially firmware) that sets the engine output. The efficient 1630cc Rotax ACE engine gives instant acceleration and a strong top speed. The 300 version reaches 67 mph and runs 0 to 60 in under four seconds.
Designed for touring, able to do more
Sea-Doo keeps upgrading its big catalog of personal watercraft. The GTX has few changes over previous models, and the boat is essentially unchanged from the 2023, but the additions are good ones. It is a complete jet ski with the versatility to go from towing to touring. The limits show when you try to keep up with more agile skis or take longer, more dedicated trips, but it can do those too.
Easy for beginners, enough for enthusiasts
The GTX uses an electronic throttle control system for precise, responsive power. The benefits are smoother and more linear acceleration, better fuel economy, and more responsive engine control. It gives you better get up and go, and it adjusts the throttle to your inputs so the power is used efficiently, which matters on a ski that asks for quick, precise handling.
The ST3 hull and handling
The ST3 hull design is what gives the GTX its handling and stability. A flat hull can make tracking difficult in rough water, so Sea-Doo keeps the GTX flat at midships and then eases it to a single-digit deadrise (the angle of the hull bottom). That brings stability at slow speeds, a steadier ride in rough seas, and less bow lift. Sea-Doo's iBR system (intelligent Brake and Reverse, a lever that slows and reverses the ski without leaving the throttle) lets you stop quickly in tight spots, and the Variable Trim System adjusts the jet nozzle angle to suit the conditions.
GPS, audio, and the screen
The GTX carries a waterproof Bluetooth audio system with 100 watts and speakers aimed at the rider, so you can play music on the water. A built-in GPS shows real-time weather, water depth, and other hazards, and on the current Limited trim it reads off a clear 8-inch panoramic display. Take the ski, the gear, and your buddies wherever the water goes.
Storage
The GTX has an Integrated Direct Access front storage system, 26.1 gallons in total, that is easy to reach and good for gear, food, and the rest. There is also a waterproof, detachable bin for electronics or valuables, and basic safety items such as a fire extinguisher and whistle are included. It is enough for a day trip but not enough for two or three day trips, which is where the LinQ coolers and bins that clip to the back come in.
Comfort
The Ergolock seat gives strong support for the rider and passengers. Deep knee pockets let you lock in and use your legs, so you can brace in rough seas and handle the ski with less fatigue. The Limited package is the most comfortable and best-equipped version.
Safety tech
Several features keep the ride safe. The iBR brake shortens stopping distance dramatically, which lowers the chance of a collision near a marina or another boat. Sea-Doo's iControl trim adjusts automatically to hold performance as conditions change, and the iDF debris-free intake clears a weed or sand-clogged pump from the helm rather than from the water. The wide, low-slung stance, deep footwells, and shock-absorbing seats add stability and cut rider fatigue.
Range
The tank holds 18.5 gallons. Ridden as a tourer at a 35 mph cruise, the GTX covers 110 to 130 miles. At 50 mph that falls to 80 to 100, and wide open it is 40 to 50. For a jet ski, that is enough range for a full day on the water.
Accessories
Sea-Doo sells accessory bundles for different uses. The watersports bundle starts around $629 with a LinQ ski pylon, a Tow-Pro rack, and a shock tube. The fishing bundle for the 300 starts around $17,499 with a LinQ 13.5-gallon cooler. Individual parts include a 12-volt outlet and kit at $56.99, a ski tow eye at $54.99, and a retractable ski pylon at $449.99, along with covers and docking accessories.
Is it worth the money?
The GTX is a premium touring jet ski that can do almost everything except race. At a starting price around $15,200 for the 170 hp, the real question is whether to step up to the 230 or 300 for the relatively small upgrade. With 300 horsepower, the second most powerful engine in the Sea-Doo line, it is built for offshore performance, and the big swim platform with LinQ points makes it a fine ski for a day out with friends or family. The catch is the price. A GTI SE starts around $11,499 and covers most of what a casual rider wants, so the GTX extra power and amenities can be wasted on someone who does not take it offshore. For open-water riders who use the power, it is one of the best touring skis you can buy.
