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 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 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
Exhaust
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 Pump
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 consistent 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 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
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
Strong Light Hull Design
Feedback from Kawasaki�s IJSBA championship-winning racing machines integrated into design enables it to cope with the engine�s horsepower
Hull offers a combination of straight tracking and responsive handling in both calm and rough-water conditions
The lower hull is designed to distribute the engine and power delivery loads over a wide area
The 300LX�s deep-V hull enables a high bank angle and motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding
The ideal 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
The bottom of the hull slants upward steeply from the center section to the bow, so the Ultra 300LX 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 300LX�s excellent maneuverability while helping to retain the narrow hull design
Quattro KSD
The Ultra 300LX�s Kawasaki Splash Deflector uses three bottom-mounted ridges and an additional deflector mounted at the top to deflect water splashing forward from under the hull
Whether turning or rocketing forward, at high speeds or low, the Quattro KSD minimizes spray, allowing greater rider concentration
Luxury, Comfort and Convenience
Five-way adjustable handlebars allow operation while standing or sitting and suit a wide range of riders
Two-tone LXury seat is ultra comfortable whether riding stand-up, seated or with passengers
Seat offers roomy accommodations for three people
Ergonomic deck design gives plenty of legroom
GPS-mountable handlebar pad accommodates a variety of GPS devices
A long rear boarding step and dual grab handles make it easy to climb onboard, and the step retracts inside the bumper to prevent damage
A quick and easy hose connection allows a simple method to flush sea water out of the engine
Mirrors are mounted to the upper deck to facilitate opening of the hatch cover
Capacious Storage
The Ultra 300LX offers 60 gallons of total storage capacity
The large-capacity, fully sealed storage area with a detachable storage tray has plenty of room for recreational equipment
A detachable drink holder with space for two drink bottles is mounted on the center console
Ideal for small items like a ski rope, a compact storage area is integrated with the under-seat rear grip
Extra Large Fuel Capacity
20.6-gallon fuel tank has more fuel capacity than any machine in its class
Digital Instrumentation
Highly legible LCD screen
Instrumentation includes riding modes, as well as external water and air temperature; clock; time, trip and hour meters; tachometer (in digital or graph displays); speedometer and max speed functions
Eco Indicator shows when the 300LX�s speed and throttle opening is in its most efficient range
