Performance & Handling:

S Is For Size and Stability
Enjoy a smooth ride in almost any water condition on this large, luxurious ride. And thanks to its legendary S³ Hull, you’ll stay glued to the water and enjoy reduced drag for all around better handling.

The First of its Kind
The S³ Hull has a stepped design that reduces drag while staying glued to the water, for a stable and consistent ride that also improves fuel efficiency. It’s also incredibly strong, thanks to its ribbed construction. This means you get better handling.

Change on the Fly
Choose from different riding styles with the touch of a button.

Tune Your Craft’s Attitude
Adjust the nose angle of the watercraft higher (stability at high speeds) or lower (for towing and quick starts). You can quickly access the Variable Trim System (VTS) on the handlebar for fine-tuned handling based on rider preference, water conditions, and number of passengers.

The Legend Continues
Each Sea-Doo watercraft comes equipped with a legendary Rotax 4-TEC engine, specifically designed for marine use. Not only do you get quicker acceleration and a higher top speed, your Rotax engine also works hand in hand with iTC to provide more precise engine calibration. What this means is better fuel economy for you.

Smart Storage, Smarter Savings
Stow your summer possessions in the standard Watertight Removable Storage Bin and save money with this watercraft’s Intelligent Throttle Control (iTC) and ECO mode function, that both help in providing improved fuel consumption.

Intuitive Technology
Sea-Doo is the only watercraft that starts in neutral, so the engine runs without propelling the craft forward for safer dockside starts and easy, stress-free maneuverability. And because the throttle responds to an electronic signal instead of a cable, you enjoy better fuel economy and a lower operating cost.

Intelligent Power Delivery
Automatically determines the most economical power delivery for the greatest fuel economy.

Take It With You on the Water
Removable, watertight storage for all your gear, wet or dry. Portable design gives you quick, easy access to all your essentials.

Fun and Functional
This convenient storage compartment is located in the watercraft’s platform for an additional storage option.

Easier Engine Access
Enjoy the convenience of a touring-style hinged seat to make accessing the engine simple and hassle-free. Conveniently lifts up to provide you quick, easy engine access.

One-of-A-Kind Cool
The industry’s only Closed-Loop Cooling System (CLCS) that uses coolant – instead of corrosive saltwater (and even debris) that can damage the engine – to keep it running at ideal temperatures.
