OVERVIEW

The JET SKI® STX® 310 PWC’s supercharger system is both highly efficient and smooth, delivering instant, lag-free boost and strong low-rpm torque. With the supercharger producing so much power, the intake and propulsion systems were optimized for low cavitation and ideal hook-up on acceleration so that max power is produced every time you pull the throttle lever.

The JET SKI® STX® 310 PWC’s compact hull was designed to be highly rigid and lightweight to match the high output. Designed with a shallow-V hull profile compared to the deep-V hull on the JET SKI® ULTRA® 310, the JET SKI STX 310 PWC's hull delivers steady, responsive maneuverability on flat water and smooth confidence when conditions pick up. Similarly to the engine, the hull has been developed and refined in both racing and leisure applications over the years. A tight turning radius provides exceptional low-speed maneuverability, while opening the throttle unleashes effortless, supercharged acceleration on the straightaways.

While accelerating with the system engaged, launch control is ready for use. Two modes allow either single use or repeated launches.

You can select from Full, Middle, and Low Power Operation as well as Smart Learning Operation (SLO)-Mode. A one-touch 5-mph mode is used in no wake zones. It regulates engine speed to maintain a forward speed of 5 mph.

Easily control the hull’s attitude to suit water surface conditions and riding style, making the JET SKI® STX® 310 ready for a thrilling ride every time.

Angling the jet pump upward lifts the bow to navigate rough water with confidence, while trimming downward lowers the bow for sharper, more agile cornering in smooth conditions.

Stay connected with RIDEOLOGY THE APP POWERSPORTS^†. When linked to a smartphone, call and message notifications received will be indicated on the instrument display. The instrument’s large screen size makes it ideal for infotainment functions.  

Features like the programmable waypoint indicator (GPS-based), vehicle information (including trim condition and preferred trim settings), and audio track display (when linked to an iOS-type smartphone) offer both information and entertainment value. 

Easily program highly convenient waypoint functions displaying the distance and direction to a destination. 

A rearview camera is mounted behind the rear seat and can be monitored via the instrument panel, offering a supplemental rearward view behind the vehicle. This is extremely convenient when towing a wakeboarder or docking. 

Electronic Cruise Control lets you set and maintain your speed (rpm) at a set level, which you can easily be adjusted up or down with the push of a button.

Kawasaki Smart Reverse with Deceleration (KSRD) electrically deploys the reverse bucket. The reverse assist system is activated when a thumb switch on the right handlebar is pushed, enabling the thrust to be controlled with one hand. When the thumb switch is fully depressed, the Trim up and down buttons can be used to increase or decrease the engine rpm to adjust thrust, allowing for more precise control when maneuvering the watercraft in tight spots, such as docking. When the reverse thumb switch is released, the drive mode returns to neutral, and the engine returns to idle.

The Kawasaki Smart Steering® system is a supplementary steering system designed to assist riders as they learn to turn and maneuver the JET SKI® STX® 310. The system can detect the rider’s steering input and speed of operation and automatically increases engine speed to provide additional thrust, even when the throttle is not being applied. If speed is low, the system does not operate.

The triple Kawasaki Splash Deflector (KSD) is a lateral strip on the forward section of the hull that dramatically reduces water splashing, especially at speed and in rough water.

Built-in cleats (one on each side) provide convenient cinch points when mooring at a dock.

A multi-mount bar is located below the easy-access rear pocket.

The JET SKI® STX® 310 offers a large 20.6-gal (78 L) fuel tank for extended cruising range.

The JET SKI® STX® 310 provides ample storage for a perfect day on the water. 30.1-gal (114 L) of storage up front is complemented by 1.2-gal (4.4 L) of central storage, plus a 0.2-gal (0.8 L) waterproof compartment. At the rear is a 0.7-gal (2.6 L) easy-access rear storage pocket, and 2 cupholders are located behind the instrument panel for added convenience.

Stylish LED lights built into the bumper add to the tough, unique look.

A height-adjustable ERGO-FIT® motocross-style handlebar, round grips, and a handlebar pad add looks and function, while a 2-person sport-inspired seat adds comfort.

As one of Kawasaki's flagship PWCs, the JET SKI® STX® 310 proudly wears the Kawasaki River Mark.

The JETSOUND® sound system features 2 speakers, jog dial control, and wireless connectivity.

The JET SKI® STX® 310RX comes standard with a two-step (lower & upper) rear grip that helps you reboard.
