The 2026 Kawasaki Ultra 310LX-S stands at the top of the personal watercraft market, delivering a rare combination of class-leading supercharged power, premium comfort, and cutting-edge technology. Built on Kawasaki’s flagship Ultra platform and refined under their “dynamic luxury” design philosophy, this model is engineered to provide both high-performance excitement and all-day usability.

From its aggressive styling and industry-leading engine to its advanced electronics and luxury-level features, the Ultra 310LX-S is designed for riders who expect more than just a jet ski—it’s a full on-water experience.

Engine & Performance

At the core of the Ultra 310LX-S is one of the most powerful engines available in any production PWC:

• 1,498cc inline 4-cylinder marine engine
• Supercharged and intercooled (Eaton Twin Vortices system)
• ~310 horsepower class-leading output
• Digital fuel injection for consistent performance
• High-capacity 160mm jet pump with stainless steel components

This powertrain delivers instant throttle response, aggressive acceleration, and strong top-end speed, making it ideal for everything from high-speed runs to towing and cruising with multiple passengers.

Advanced Performance Systems

• Launch Control Mode (KLCM) – optimizes trim for maximum acceleration
• Selectable Power Modes (Full / Middle / Low / SLO)
• Electronic Throttle Valve system for smooth, precise control
• Kawasaki Smart Reverse with Deceleration (KSRD) for easy maneuvering
• Economical Riding Indicator to improve fuel efficiency

The result is a watercraft that is both extremely powerful and highly controllable, adapting easily to different riding styles and conditions.

Hull Design & Ride Quality

The Ultra 310LX-S is built on a race-proven deep-V hull, engineered for stability, comfort, and control in a wide range of water conditions.

• Deep-V hull for superior rough water handling
• Excellent high-speed tracking and cornering stability
• Wide, confidence-inspiring platform
• Lowered deck design for improved rider connection
• Larger footwells for increased comfort and control

This hull design gives the Ultra 310LX-S a larger, more planted feel, making it one of the most stable and comfortable PWCs available—especially in choppy or open water.

Design, Color & Lighting – 2026

For 2026, Kawasaki continues to refine the Ultra platform with a bold, premium design update.

Factory Color

• Riptide Turquoise / Ebony

This high-contrast color combination pairs deep, rich black tones with vibrant turquoise accents, creating a sharp, modern look with excellent depth and visibility on the water. The finish is designed to highlight the aggressive lines of the hull while maintaining a clean, upscale appearance.

Dynamic Luxury Styling
