2018 Sea-Doo RXP-X 300


The ultimate top-of-the-line racing watercraft combines power, handling and control like nothing else on the water. And with the 300-hp Rotax 1630 ACE engine, nothing else will come close to you on the buoy course.


  • ROTAX 1630 ACE ENGINE: Supercharged with an external intercooler, the Advanced Combustion Efficiency (ACE) technology delivers high efficiency and amazing acceleration. This is the most powerful engine on a Sea-Doo producing a thrilling 300-hp.
  • ERGOLOCK SYSTEM: Become one with the machine by locking in your body for better handling and more control, thanks to a narrow racing seat, specially angled footwell wedges and adjustable ergonomic steering.
  • RACING HANDLEBAR WITH ADJUSTABLE RISER: With up to 3 inches (73mm) of vertical adjustment range, the telescopic steering system is ready to face the demanding conditions faced by riders of any size.
  • T3 HULL: Ready, set, race. A deep V-shaped hull—the favorite of our Sea-Doo X-Team racers—allows unmatched control and precision for the sharpest turns and unrivaled handling.
  • ADJUSTABLE X SPONSONS: An efficient design that improves cornering stability. Offers 3-position adjustability based on skill level and riding environment: higher for a more playful freeride experience or lower for sharper turns. Winglet feature also enhances lean angles during turning.
  • HIGH PERFORMANCE VARIABLE TRIM SYSTEM WITH LAUNCH CONTROL: Quickly access the Variable Trim System (VTS) on the handlebar for fine-tuned handling based on rider preference, water conditions, and number of passengers. Plus a handlebar-activated launch control to provide perfectly controlled acceleration.
  • INTELLIGENT BRAKE AND REVERSE (iBR): Recognized by the U.S. Coast Guard for improving boat safety since 2009 and now in its third generation, the Sea-Doo exclusive iBR (Intelligent Brake and Reverse) system allows you to stop up to 160 feet (48 m)* sooner than watercraft not using a brake. With both hands on the handlebars, riders can engage forward, neutral, and reverse for stable, worry-free maneuvering at low speeds.
  • INTELLIGENT THROTTLE CONTROL (iTC): Choose how you want your power delivered thanks to different riding modes such as Touring, Sport and ECO - available through your watercraft digital information center.
  • CLOSED-LOOP COOLING SYSTEM: This technology prevents corrosive saltwater and damaging debris from entering the engine, for increased reliability and peace of mind.
