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

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
