Competition Comparison
When comparing the 2019 Seadoo RXTX 300 to the 2019 Yamaha FX SVHO, the RXTX 300 carves its niche with exceptional handling and groundbreaking stability due to its ST3 hull design. The Yamaha FX SVHO, known for its luxury-oriented features like Cruise Assist and its comfortable seat design, appeals to riders who prioritize long-distance touring and refined ergonomics. However, the 2019 Seadoo RXTX 300 counters this with a more aggressive riding stance, making it ideal for performance enthusiasts.
While both models have robust engines, the RXTX 300’s 300 horsepower supercharged Rotax engine delivers thrilling acceleration and top speeds on par with Yamaha’s high-output motor. Additionally, the RXTX 300 features a more intuitive iBR braking system, giving it an edge in responsive control and safety. The 2019 Kawasaki Ultra 310X is a powerhouse, boasting the highest horsepower in the industry at 310 hp, which makes it a beast in straight-line speed and wave-busting capability. Despite this, the 2019 Seadoo RXTX 300 proves more agile, especially in choppy waters, thanks to its lightweight CM-TEC hull and ergonomic seating that ensures better rider stability.
Kawasaki’s focus on brute strength often overshadows practical features, where the RXTX 300 shines with its intelligent storage solutions and refined user experience. Riders looking for an all-around machine will appreciate the RXTX 300’s Eco mode for better fuel efficiency and its rear cargo LinQ attachment system, which sets it apart in versatility. While the Ultra 310X may dominate in raw power, the RXTX 300 strikes a better balance between performance and usability.
In terms of value, the 2019 Seadoo RXTX 300 sits between the Yamaha FX SVHO’s premium feel and the Kawasaki Ultra 310X’s performance-first approach. It combines features like a spacious 27.1-gallon storage capacity and cutting-edge technology such as Variable Trim System (VTS) to offer a ride that caters to both thrill-seekers and recreational riders. For towing water sports, the RXTX 300 holds its own with its substantial weight capacity and intelligent design, rivaling the Yamaha’s towing features while outpacing the Kawasaki in practicality. Overall, the 2019 seadoo RXT X 300 delivers a compelling mix of innovation, performance, and comfort, making it a standout choice in its class.
Special Notes or Personal Experience
I personally have had the opportunity to ride several of these skis and have found the acceleration and power is amazing for its size and the ergonomic seat allows you to stay locked into the ski while cornering at high speeds. The special contour of the hull allows it to handle choppy conditions very well. I would compare it to the way a Cadillac handles speed bumps, that’s what it feels like going over choppy waves in this ski.
My overall impression of this ski is that it was built to handle multiple tasks with its impressive power, stability, and ergonomic seat, it has alot to offer, and if you get a chance to ride one don’t pass up the opportunity.
Conclusion
The 2019 Seadoo RXTX 300 is a testament to Sea-Doo’s dedication to delivering cutting-edge personal watercraft that cater to a variety of riders. With its industry-leading ST3 hull, this jetski sets the bar high for stability and performance, excelling in both flat and choppy water conditions. The supercharged Rotax engine ensures exhilarating acceleration and speed, while features like the iBR braking system and VTS add an extra layer of control and safety.
