Sea-Doo's designers paid close attention to creating the most comfortable cockpit possible; the footwells are deep and surprisingly wide, allowing the rider plenty of room to move around the watercraft. The Ergolock seat is smartly sculpted to fit most adult riders, and features angled footwedges to help position the driver's knees into the padded coves for better handling.
Of course, the RXT-X's centrifugally supercharged 1,630cc 4-stroke producing a solid 300-horsepower is the big draw here. Not only could the new 2018 RXT-X out accelerate the competition, but its previous model as well. For 2018, Sea-Doo engineers shaved off an incredible 86-pounds, putting the new performance 3-seater at 828-pounds compared to the previous 914-pounds.
In all, the 2018 Sea-Doo RXT-X 300 is an absolute riot; with arm-stretching acceleration; a super comfortable cockpit; packed to the roof with one-of-a-kind special features. This new Sea-Doo was just a joy to ride.

Overview
The Sea-Doo RX-PX300 represents a breakthrough in performance watercraft accessible to the general public, offering a racing machine experience akin to professional riders. With a 300-horsepower engine and a hull design identical to those used in professional racing—albeit with less power to comply with legal restrictions—this model delivers exceptional speed, agility, and rider engagement. It is designed for experienced riders seeking a high-performance craft that continuously challenges and improves their skills.
Exterior Design and Ergonomics
The RX-PX300 features a bold, aggressive exterior with sharp angular lines starting from the bow and extending through the hull. The design includes rounded chines that facilitate leaning into turns, enhanced sponsons for adjustable water grip, and a drop-down keel that acts as a pivot point for initiating rolls. Integrated mirrors are positioned within the dock strike zone and are fully adjustable to suit individual riders. Storage compartments are thoughtfully placed throughout. The ergonomics are refined through Sea-Doo's Ergolock system, developed with input from an ergonomics specialist to create a seamless connection between rider and machine. The footwell allows foot positioning adjustments for cornering or straight-line riding, while the redesigned seat enables the rider to grip the craft firmly using the strongest muscle groups, forming a stable triangular contact system that enhances comfort and control.
Powertrain and Performance
At the heart of the RX-PX300 is a redesigned 1630 cc engine, which is 9% larger than its predecessor and delivers 15% more power. Key enhancements include a longer stroke for improved mid-range torque, lighter and stronger pistons and connecting rods, larger fuel injectors, and an intercooler that is 120% more efficient at delivering cooler air to the combustion chamber. Although top speed is electronically limited in compliance with Coast Guard regulations, the craft excels in rapid acceleration and efficient power delivery, allowing riders to reach top speed quickly and maintain high performance throughout maneuvers. Fuel consumption varies with speed, ranging from 2.9 gallons per hour at 20 mph to 15.3 gallons per hour at 60 mph, resulting in an approximate range of 56 miles.
Technology and Controls
The RX-PX300 incorporates advanced rider-focused technology to enhance control and safety. On the left handlebar, the start-stop button is complemented by palm rests for ergonomic hand positioning and the Intelligent Brake and Reverse (IBR) lever, which allows for safe stopping from high speeds and precise maneuvering in tight spaces. The craft features a variable trim system (BTS) to optimize running attitude and performance, with selectable modes including Touring for relaxed cruising, Sport for aggressive riding, and Eco for fuel-efficient operation. The right handlebar controls the digital dashboard, enabling riders to scroll through information and adjust display settings. Adjustable Ergonomic Steering (AES) allows fine-tuning of handlebar rotation and lateral position to match rider preferences, ensuring symmetrical and comfortable control.
Handling and Riding Experience
The RX-PX300 delivers exceptional handling characteristics, particularly in cornering and lap racing scenarios. Its design encourages riders to lean into turns, using weight shifts and the Ergolock system to maintain grip and stability. Acceleration out of turns is strong, enabling quick transitions between buoys and tight maneuvering. The craft challenges riders to accelerate through turns rather than coasting, fostering skill development and enhancing the overall riding experience. While it demands a higher level of rider proficiency, the RX-PX300 rewards with a heightened sense of control and responsiveness, making it a formidable machine for performance enthusiasts.
Conclusion
The Sea-Doo RX-PX300 is a high-performance watercraft that bridges the gap between professional racing machines and public accessibility. Its combination of advanced engineering, ergonomic design, and rider-focused technology creates a powerful yet controllable craft that continually pushes the boundaries of personal skill and enjoyment on the water. While not suited for casual riders, it offers an unparalleled experience for those seeking to elevate their performance riding to a professional level.
