Overview

Kawasaki Jet Ski Ultra 310X

The World’s Most Powerful PWC Returns With Even More Thrust On Tap

Personal watercraft (PWC) innovators for four decades, Kawasaki surprised the entire industry when it debuted the Jet Ski® Ultra® 300X watercraft in 2011. Now a substantially improved Jet Ski Ultra 310X watercraft raises the PWC stakes before the competition has even had a chance to place a 300 class bet!

Thanks to key improvements to its supercharged inline four-cylinder engine, the monumental horsepower of the previous X-model is getting a boost for 2014. The hint lies in the new model name: Ultra 310X astonishes yet again with 310 horsepower – the most available in any production personal watercraft – to propel a sporty-handling hull that’s capable of tackling rough water with ease or comfortably hauling three adults in addition to an impressive payload. Power, handling, versatility. Ultra 310X brings it in ways the competition simply can’t.

With 310 horsepower1 on tap, the Ultra 310X’s Digital Fuel Injected (DFI) 1,498cc engine is the reigning king of thrust, and its crown is the high-tech Eaton TVS series supercharger. Along with Kawasaki’s Electronic Throttle Valve (ETV) system, the supercharger gives the engine exhilarating yet linear power, and its race-derived hull design is capable of carving precise turns in a wide range of water conditions, from sheet-glass to chopped-surf; exactly what hard core performance enthusiasts would expect from a Kawasaki Jet Ski PWC.

**Horsepower measured in PS at the crankshaft under controlled conditions. Actual performance may vary.

Eaton Twin Vortices Roots-Type Supercharger

Kawasaki Jet Ski Ultra 310X

• Four-lobe, constant-displacement design offers significant performance increase over standard roots-type unit
• System force-feeds the engine two liters of air with every revolution, providing a constant supply of high-pressure intake air at all rpm
• Delivers compressed air continuously, not in waves, for smoother power delivery
• Produces large amounts of boost even at low rpm for instant and powerful acceleration right off of idle
• Provides a flat and linear torque curve with mellifluous, lag-free power across the entire rev range Produces more low-rpm boost than competitive or aftermarket systems, with a maximum of 17 psi of boost pressure
• Two different air bypass valves are used to prevent over boosting at low and medium rpm

Air-To-Water Intercooler

Kawasaki Jet Ski Ultra 310X

• Efficiently cools high-pressure intake air – cooler air is denser and makes more power
• Liquid-cooled intercooler design maintains consistent thermal performance

Digital Fuel Injection System

Kawasaki Jet Ski Ultra 310X

• High-flow fuel injectors with four orifices are fitted for combustion efficiency
• Single throttle body features a large, 60mm bore diameter

Exhaust

Kawasaki Jet Ski Ultra 310X

160MM Jet Pump

Kawasaki Jet Ski Ultra 310X

• Large-diameter, race-developed 160mm jet pump efficiently converts the Ultra 310X’s massive horsepower output into instantaneous thrust
• Pump is designed to deliver consistent output and good “bite” even in rough water conditions
• UPGRADED Impeller features a revised 3-blade design that gives the 310X greater initial acceleration
• Eight-vane intake guides and regulates the flow of water to the impeller for consistent, efficient and powerful propulsion

Ride Plate

Kawasaki Jet Ski Ultra 310X

• Features a groove from the center to the rear of the plate to enhance straight-line tracking

Electronic Trim Control System

• Allows the angle of the jet pump nozzle to be controlled to adjust the attitude of the hull to suit water surface conditions and riding styles
• Adjustment range is plus or minus 8 degrees from standard

Electronic Throttle Valve (ETV) With Cruise Control

• IMPROVED Fuel Economy Assistance mode revised for significant fuel savings and increased range
• Convenient electronic cruise control smoothly holds a set speed from 5 mph up to top speed
• Accelerator Position Sensor (APS) converts throttle lever input to an electronic signal that’s used to control the throttle valve via an electric motor for crisp and smooth throttle response

• Reinforced inner bow is extremely light with ample strength to handle the engine’s power output
• Exemplary straight-line tracking and responsive handling in both calm and rough-water conditions set performance benchmarks for the class
• The lower hull is specially designed to distribute the engine and power delivery loads over a wide area
• Deep-V hull design enables a steep bank angle for motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding
• The 22.5-degree V-angle at the bottom of the hull helps reduce unwanted spinouts during sharp turns
• Delivers the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous
• Bottom of the hull slants upward steeply from the center section to the bow, so the 310X can penetrate swells and waves with less shock, pushing through waves rather than bouncing over them at high speeds
• Integrated sponsons extend from the hull, providing wallow-free straight-line performance and contributing significantly to the 310X’s excellent maneuverability while helping to retain the narrow hull design

Quattro KSD
