Sea-Doo RXT-X 300: BoatTEST Review
Overview
The Sea-Doo RXTX 300 is a high-performance watercraft designed to deliver speed and exceptional handling even in challenging water conditions. It accommodates up to three riders and emphasizes a strong connection between the machine and the rider through advanced ergonomic and technological features. This watercraft is suitable for both thrill-seekers and families, offering ample storage and ease of use around docks.
Exterior Design and Ergonomics
The RXTX 300 features clean lines with subtle angular geometry, complemented by integrated, fully adjustable mirrors positioned safely within the dock strike zone. A standout aspect of its design is the Ergolock system, developed with input from an ergonomics expert to make the vehicle an extension of the rider. This system includes a footwell with distinct positions for cruising and cornering, a redesigned seat that locks the rider in place by allowing the knees to press inward, and a raised seat back that provides additional support. Together, these elements create a triangular support system enhancing rider control and comfort.
Control and Technology
The RXTX 300 incorporates several advanced control features starting with the Adjustable Ergonomic Steering (AES), which allows the handlebars to be rotated and adjusted in and out with guide marks ensuring symmetry. Uniquely, the gauges adjust in tandem with the handlebars for optimal visibility. The left handlebar hosts the start-stop button, a palm-rest grip, the Intelligent Brake and Reverse (IBR) lever for safe stopping and maneuvering, the Variable Trim System (VTS) for adjusting riding attitude, and mode toggles between Touring, Sport, and Eco for performance or fuel efficiency. The right handlebar controls the digital display, allowing the rider to cycle through information such as speed, lap timer, fuel consumption, and trim parameters.
Power and Storage
Beneath the hinged seat, supported by a gas strut, lies a redesigned 1630cc supercharged and intercooled engine. This engine is 9% larger than its predecessor and delivers 15% more power. Storage options include a watertight compartment under the front visor with a removable insert, secure storage for safety equipment such as a fire extinguisher and flares, and a large rear deck that facilitates boarding and towing. The RXTX 300 is tow-friendly, equipped with a rear hook and multiple handholds for passengers. Additionally, retractable dock lines are conveniently located at the sides and stern, eliminating the need to carry extra lines.
Performance and Handling
On the water, the RXTX 300 demonstrates highly responsive and instantaneous acceleration and maneuverability. Although top speed is regulated by Coast Guard agreements, the watercraft maintains impressive fuel efficiency, consuming 6.4 gallons per hour at 40 mph, 9.8 gallons per hour at 50 mph, and 14.8 gallons per hour at 60 mph. These figures allow for up to an hour of run time with a 10% fuel reserve. The combination of performance, handling, and the Ergolock system provides a ride that balances the thrill of speed with comfort and control, even in less than ideal water conditions.
Conclusion
The Sea-Doo RXTX 300 stands out as a muscle car on the water, blending high performance and precise handling with ergonomic comfort and advanced technology. Its design and features foster a strong connection between rider and machine, enhancing both enjoyment and control. This watercraft is well-suited for riders seeking speed without sacrificing comfort or practicality.
