Features

At Rest. At Speed. Always Steady.

  • STABLE AND PREDICTABLE HULL: Whether you’re at high speeds pounding rough offshore waters, at rest hanging out in a cove or you’re simply boarding from the side, the wider hull offers industry leading stability thanks to a lower center of gravity and improved hull design.

Closed-Loop Cooling System

  • A SEA-DOO EXCLUSIVE: This technology prevents corrosive saltwater and damaging debris from entering the engine, for increased reliability and peace of mind.

Features

  • HULL TYPE: ST3 Hull™
  • ALSO INCLUDES: iControl®, ECO® Mode, Ergolock™ System, Trim Tabs, Launch Control, Ski Tow Eye, RF D.E.S.S.™ Key, LinQ™ Attachment System, Wide-Angle Mirrors, Handlegrip with Palm Rests, Footwell Carpets, Large Swim Platform, Tilt Steering.

Ingenious Storage

  • DIRECT ACCESS FRONT STORAGE: All your gear is now within arm’s reach. The industry’s first direct-access front storage opens by simply raising the handlebar assembly. No standing required. It's the smartest water-resistant storage we've ever built into a watercraft, offering room for your next adventure.

Intelligent Brake and Reverse

  • THE INDUSTRY’S FIRST AND MOST INTUITIVE ON-WATER BRAKE: Recognized by the U.S. Coast Guard for improving boat safety and now in its third generation, the Sea-Doo exclusive iBR system allows you to stop sooner. With both hands on the handlebars, riders can engage forward, neutral, and reverse for stable, worry-free maneuvering at low speeds.

Large Swim Platform

  • CONFIGURABLE. COMFORTABLE. GROUNDBREAKING: The first watercraft to hang out on the water with the largest swim platform in the industry. Flat, stable and comfortable, it is ideal for boarding, lounging, and prepping for tow sports. Create even more space by removing the rear seat.

Lock In Your Seat

  • ERGOLOCK SYSTEM WITH MODULAR SEAT: The narrow racing seat places your knees closer together to hold on tighter while improving the transition into standup riding. Plus, the removable rear seat gives you even more space for hanging out on the rear platform, sunbathing or a face-to-face picnic.

Music Onboard

  • BLUETOOTH AUDIO-PREMIUM SYSTEM: The industry's first fully-integrated waterproof Audio System will keep the fun going anywhere you go, with 100 watts of total system power, fully-waterproof performance, Bluetooth connectivity, and external playback controls to ensure the perfect song is always on deck.

Precision Tuning

  • 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.

Rear Cargo LinQ System

  • FAST. EASY. SECURE: Extra rear storage is now possible with the secure quick-attach LinQ system. It allows to easily snap a fuel caddy and a bag, or a cooler, to the back of your watercraft using two convenient, integrated attachment points.

The Most Powerful Engine on a Sea-Doo, Ever:

  • 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.

Wide Digital Display

  • FULLY DIGITAL GAUGE: The 7.6 inches wide digital display offers riders an improved user experience when cycling through modes and locating vehicle information. It also features an automatically dimming backlight that ensures high visibility in any light. The larger display area makes for improved visibility when riding.

X Package

  • TAKE PERFORMANCE FURTHER: Add on the performance package. With X-Sponsons for cornering stability and our innovative ErgoLock System featuring a narrow racing seat, specially angled footwell wedges and adjustable X-steering, you and the machine become one.
