Offshore Performance with Everyday Versatility

The RXT-X is designed for high-performance riding across larger lakes, rivers and changing water conditions. Its ST3 hull and Ergolock system provide a more stable, connected riding experience than smaller recreational platforms, while its 325-horsepower engine delivers the acceleration experienced riders expect from a flagship performance model.

The Sea-Doo RXT-X is a strong choice for:

• Experienced performance riders
• Offshore and rough-water riding
• High-energy recreational use
• Riding with one or two passengers
• Riders who want 325 horsepower with three-person capacity
• Buyers comparing the RXP-X and GTX Limited
• Longer open-water rides with premium technology

2026 Sea-Doo RXT-X 325 Specifications

These figures are based on Sea-Doo’s official Canadian specifications. Equipment, colours, prices and availability can change, so customers should confirm current details with Cartronics Powersports.

Key Sea-Doo RXT-X Features

Supercharged Rotax 1630 ACE Engine

The RXT-X is powered by a supercharged Rotax 1630 ACE engine producing 325 horsepower. An external intercooler supports the high-output design, while Sea-Doo’s Closed-Loop Cooling System circulates coolant through the engine instead of using surrounding lake or river water for internal engine cooling.

The RXT-X requires premium 91-octane gasoline and uses Sea-Doo’s Intelligent Throttle Control system. Its combination of strong acceleration and offshore stability is central to the model’s performance-focused design.

Fiberglass ST3 Hull

The fiberglass ST3 hull is engineered for rough-water handling, stability and offshore performance. Its larger, planted design provides greater confidence when riding through moderate chop, carrying passengers or crossing open stretches of water.

The ST3 platform makes the RXT-X particularly well suited to:

• Open-water riding
• Larger lakes and rivers
• Rougher conditions
• High-speed offshore runs
• Carrying passengers
• Riders who want stability without sacrificing performance

Hydraulic Steering Damper

The RXT-X includes a hydraulic steering damper with three selectable resistance positions. It is designed to reduce unwanted steering movement in rougher conditions and allows riders to adjust the steering feel to suit the water, speed and personal preference.

A lighter setting may be useful for relaxed operation and low-speed manoeuvring, while increased resistance can provide a more deliberate steering feel during aggressive or rough-water riding.

Ergolock Racing System

The two-piece Ergolock racing seat uses a narrow profile and deep knee pockets to help riders secure their lower body against the machine. This reduces unnecessary movement and helps the rider stay connected during acceleration, cornering and changing water conditions.

The RXT-X also includes:

• Low-rise racing handlebar
• Tilt steering
• Full-length angled footwell wedges
• Knee pads
• Footwell carpeting
• Round grips

Together, these features create a more performance-oriented riding position than the touring-focused GTX lineup.

X-Sponsons

Performance-oriented X-sponsons help sharpen cornering response and contribute to the RXT-X’s controlled, aggressive personality.

They work alongside the ST3 hull, Ergolock seat and footwell wedges to help experienced riders maintain control during higher-energy manoeuvres.

Launch Control Mode

Launch Control is included among the RXT-X’s Intelligent Throttle Control settings. It provides a dedicated acceleration-focused mode alongside Eco, Sport, speed regulator and slow-speed functions.

Launch Control should be used responsibly in open water, away from swimmers, docks, shorelines and other vessels.

Extended Variable Trim System

The RXT-X includes an Extended Variable Trim System, allowing riders to adjust the watercraft’s running angle over a broader range.

Changing the trim can affect bow position, acceleration, cornering response and how the watercraft reacts to passenger loads and changing conditions. The selected position is displayed on the touchscreen.

Stainless-Steel Polished Impeller

A polished stainless-steel impeller is included as part of the RXT-X performance equipment. It helps convert the engine’s output into jet-pump thrust and supports the model’s strong acceleration.

10.25-Inch Touchscreen Display

The 2026 RXT-X includes a 10.25-inch touchscreen, replacing the smaller display used on previous model years.

Its functions include:

• Speedometer and engine rpm
• Fuel consumption and estimated range
• Ride statistics
• Top and average speed
• Extended VTS position
• Vehicle operating hours
• Bluetooth connectivity
• Music controls
• Compass
• Marine navigation through BRP Connect and the BRP GO! app

Sea-Doo developed the display specifically for on-water use, combining vehicle information, entertainment and connected navigation in one interface.

Premium BRP Audio System

A factory-installed Premium BRP Audio System is included on the 2026 RXT-X. The waterproof system connects to compatible mobile devices through Bluetooth, while media functions can be managed through the touchscreen display.

A USB port is also included for charging a compatible device.

Intelligent Brake and Reverse

Sea-Doo’s electronic iBR system provides braking, neutral and reverse through handlebar-mounted controls.

Neutral and reverse improve low-speed manoeuvrability around docks, launch ramps and trailers. The braking function gives riders additional control when slowing the watercraft.

Direct-Access Front Storage

The RXT-X provides 98.9 litres of total storage, including a 96-litre front compartment and a 2.9-litre glove box. The direct-access front design makes it easier to reach equipment and personal belongings during an outing.

Storage can be used for items such as:

• Safety equipment
• Dock lines and bumpers
• Tow ropes
• Towels and clothing
• Dry bags
• Personal flotation devices
• Smaller coolers
• Personal belongings

A watertight phone compartment is also included.

Large Swim Platform with LinQ

The RXT-X includes a large rear swim platform with Sea-Doo’s integrated LinQ attachment system.

Compatible coolers, storage bags, fuel containers and other accessories can be attached or removed without conventional tools. The platform also provides useful space for boarding, preparing for watersports or relaxing while the machine is stationary.

Is the Sea-Doo RXT-X Good in Rough Water?

The RXT-X is specifically designed for offshore performance and rougher-water confidence. Its fiberglass ST3 hull, hydraulic steering damper, Ergolock seating system and rider-supporting footwell wedges are intended to improve stability and control in changing conditions.

No personal watercraft can eliminate the risks associated with wind, waves, cold water or rapidly changing weather. Riders should check marine forecasts, reduce speed when conditions deteriorate and avoid exceeding their own experience level.

Is the Sea-Doo RXT-X Good for Beginners?

The RXT-X includes several features that can assist with normal operation, including electronic braking and reverse, slow-speed mode, wide-angle mirrors and adjustable steering resistance.

However, its 325-horsepower supercharged engine, strong acceleration and performance-focused handling make it better suited to an experienced and responsible rider. New owners may find the Spark, GTI, GTI SE or naturally aspirated GTX 170 more approachable.

Anyone new to the RXT-X should begin in an open area, use conservative throttle inputs and become comfortable with docking, steering, trim and braking before selecting Launch Control or more aggressive settings.

Is the RXT-X Good for Passengers?

The RXT-X accommodates up to three riders and has a maximum listed weight capacity of 600 pounds. Its stable ST3 hull and two-piece seat provide considerably more passenger flexibility than the solo-focused RXP-X.

The model is still performance-oriented, so operators should warn passengers before accelerating and ensure everyone is seated correctly and wearing an appropriate personal flotation device.

Can the Sea-Doo RXT-X Pull a Tube?

The RXT-X includes a ski tow eye and accommodates three riders, making it suitable for approved recreational towing when properly equipped and operated.

In Canada, the boat must have an available seat for each person being towed, and someone other than the operator must continuously watch the person behind the watercraft. Local restrictions and permitted towing hours may also apply.

Sea-Doo RXT-X vs RXP-X

The RXT-X 325 and RXP-X 325 use the same high-output Rotax engine, but their hulls, capacity and intended uses differ.

Choose the RXT-X when you want:

• Seating for up to three riders
• Fiberglass ST3 offshore hull
• More rough-water stability
• Standard Premium BRP Audio
• Standard 10.25-inch touchscreen

• Closed-course and buoy-course handling
• Greater built-in storage
• Lower starting price
• Optional two-rider capacity with an accessory seat

The RXT-X weighs 842 pounds dry and offers 98.9 litres of storage. The RXP-X weighs 778 pounds, offers 153.7 litres of storage and is configured for one rider unless its accessory passenger seat is added. The RXT-X starts at $26,849 in Canada, while the RXP-X starts at $24,549.

Choose the RXT-X when offshore stability and passenger capacity are priorities. Choose the RXP-X when solo precision and race-focused handling matter more.

Sea-Doo RXT-X vs GTX Limited

The RXT-X and GTX Limited share the 325-horsepower Rotax engine, ST3 fiberglass hull, three-rider capacity, 10.25-inch touchscreen and Premium BRP Audio. Their personalities and equipment priorities are different.

Choose the RXT-X when you want:

• Offshore performance
• Racing-style Ergolock seat
• Low-rise performance handlebar
• X-sponsons
• Angled footwell wedges
• Launch Control
• Extended VTS
• A more aggressive riding character

Choose the GTX Limited when you want:

• A more relaxed riding position
• All-day cruising refinement
• Touring-oriented convenience
• The flagship luxury Sea-Doo experience

The RXT-X currently starts at $26,849, while the GTX Limited starts at $27,999 in Canada.

Choose the RXT-X when offshore performance and rider control come first. Choose the GTX Limited when premium touring comfort and luxury are the priorities.

Sea-Doo RXT-X vs GTR-X

The RXT-X and GTR-X are both three-rider performance watercraft, but they use different hull platforms and engine outputs.

The RXT-X offers 325 horsepower, an ST3 fiberglass offshore hull, hydraulic steering damper and standard 10.25-inch touchscreen. The GTR-X produces 300 horsepower and is positioned as a more accessible performance model with a lighter, more playful platform and a lower starting price of $22,049.

Choose the GTR-X when playful handling, value and accessible performance are the priorities. Choose the RXT-X when rough-water stability, 325 horsepower and premium offshore equipment matter more.
