Whether choosing an ideal ride for a jaunt around the lake or a long-distance ocean cruise, the Jet Ski® Ultra® 300LX is the ultimate combination of superior performance and luxury accommodations. With an engine that puts out serious horsepower, a scalloped luxury seat and a host of other comforts, this watercraft means serious business when it comes to fun.

Key Features

• Supercharged, intercooled 1,498cc engine puts out incredible power but is still designed for durability and reliability

• Plush, scalloped luxury seat enhances comfort during high-speed cruising. Two-tone upholstery accentuates the functional bolsters for rider and passenger

• GPS mounting area is built into handlebar pad for convenient placement of navigation devices

• Stylish upper deck enhanced by rich metallic titanium color with luminous vintage red graphics

• Massive, industry-leading storage capacity lets you bring your gear with you

• Largest fuel tank in class keeps the fun going longer

• Five-position adjustable handlebars accommodates a range of riders

• Separate keys for full power operation and Smart Learning Operation

300-horsepower Supercharged Engine

• Supercharged and intercooled 1,498cc, liquid-cooled inline four-cylinder engine

• Cast pistons with machine finishing for excellent durability

• Stronger hardened nickel valves offer superior heat resistance and enhanced reliability

• 33.4mm intake and 28.3mm exhaust valves

• Two-layer oil cooler for efficient cooling

• Reinforced crankcase adds to engine’s durability and reliability

• Plastic intake manifold for weight savings

• Optimum cylinder wall temperature is maintained by a check valve between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, keeping the cooling water inside the cylinder jacket

• Precise power adjustments are easy with a throttle lever designed to prevent finger fatigue on longer rides

Eaton Twin Vortices Series (TVS) Roots-type Supercharger

• Four-lobe design offers significant performance increase over standard roots-type unit

• System force-feeds the engine two liters of air with every revolution, providing a stable 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 idle

• Provides a very flat and meaty torque curve with step-free power across the entire rev range without any of the lag associated with turbochargers

• 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

• Efficiently cools high-pressure intake air, as cooler air is denser and makes more power

• Cooler air results in higher combustion efficiency and high engine output

• Liquid cooling allows the intercooler to maintain consistent thermal performance

Digital Fuel Injection System

• High-flow fuel injectors with four orifices are fitted for combustion efficiency

• Single throttle body per cylinder features a large, 60mm bore diameter


• 4-into-2-into-1 powerboat-style exhaust system routes the exhaust pipe upward

• Allows the smoothest path for exhaust gases, maximizing exhaust efficiency

160mm Jet Propulsion

• Efficiently converts the Ultra 300LX’s massive horsepower output into thrust using a 160mm-diameter jet pump

• Developed from Kawasaki’s racing machines, this pump was specially designed to deliver stable output and good “bite” even when riding on rough water

• Impeller features a 3-blade design that translates the 300X’s engine output into superb acceleration performance and quiet operation

• An eight-vane intake guide is used to smooth and regulate the flow of water from the impeller for efficient and powerful propulsion

• Left-side reverse lever offers easy operation

Ride Plate

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

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

• 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 optimum throttle response and smoothness

• Redundancy in the system helps ensure control is maintained in case of failure

• One-touch 5 mph mode allows push button no-wake zone riding

• Fuel Economy Assistance mode allows maximum fuel efficiency when going slow

• Economical Riding Indicator mode can be viewed on a graph on the LCD info screen

• Cruise control smoothly holds the 300LX at a set speed from 5 mph up to top speed

Kawasaki Smart Steering®/SLO Mode

• Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, raises rpm to help initiate a turn

• Smart Learning Operation (SLO) allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace

• Two separate keys, one for SLO mode and one for full-power operation, help prevent confusion over which setting is in use
