1 2013 Model Information MODEL NAME: Ultra 300X MODEL CODE: JT1500DF DOMINANT PERFORMANCE Kawasaki JET SKI personal watercraft have a long history of high performance. Our flagship PWC offers dominant performance care of a Eaton Twin Vortices Series (TVS) Roots supercharger. This is complemented by a number of features to ensure this high output is manageable, and technology features that further contribute to enhanced comfort and control. Delivering high levels of performance and excitement, Kawasaki s JET SKI ULTRA 300X sets the standard for PWC performance.

2 DOMINANT PERFORMANCE Eaton Twin Vortices Series (TVS) Roots Supercharger TVS Roots supercharger with 4-lobe rotors enables 221 kw (300 PS) Performance comparison with ULTRA 260X Max Output 221 kw (300 PS) (up 30 kw (40 PS)) Supercharger Efficiency +28% Mechanical Loss -10% SC Unit Size About 1/2 volume Boost Pressure Up from 11.0 psi to 17.0 psi MASSIVE POWER. IMPRESSIVE ACCELERATION. Fitted with a supercharger and intercooler, the ULTRA 300X s liquid-cooled 1,498 cm3, In-line 4-cylinder marine engine produces an output much greater than a normally aspirated engine of the same displacement. The supercharger elevates engine output to 221 kw (300 PS). Supercharger and Intercooler The Roots type supercharger is known as a fixed displacement supercharger. This design produces large amounts of boost even at low rpm, for instant and powerful acceleration right off of idle. With every revolution it force-feeds the engine 2 litres of air (theoretical volume is 2,019.3 cc per engine revolution), ensuring a stable supply of high-pressure intake air at all rpm. The result is a very flat and meaty torque curve and step-free power across the rev range, with none of the time lag associated with turbochargers. Twin Vortices Series (TVS) Roots supercharger, featuring twin 4-lobe rotors, offers a significant performance increase over the previous unit. Maximum output is increased to 221 kw (300 PS), supercharger efficiency is up 28%, and mechanical loss is reduced 10%. The new unit itself takes up about half the space of the old supercharger. Boost pressure is increased from 11.0 psi to 17.0 psi. Where the 250/260X supercharger delivered compressed air in waves, the TVS unit offers continuous delivery, contributing to smoother throttle response. Internal planetary gearing increases supercharger speed 2.1 times, to ensure the necessary speed to deliver the high power output. An external pulley has a 0.9 reduction ratio. This combination delivers the required rotational speed while ensuring a low belt load. To ensure ideal intake air pressure, not one, but two air bypass valves are used. A vacuum air bypass valve is used to balance air pressure upstream and downstream of the throttle body. It works mostly at low and medium rpm. A second, regulatory air bypass valve aids the vacuum air bypass valve in preventing over-boosting when the throttle is shut (or opened) suddenly. Should the system s specified maximum pressure be exceeded, the regulatory air bypass valve is activated, allowing air to escape. Efficiently cooling the high-pressure intake air is a liquid-cooled intercooler. Friction between the air molecules heats the intake air to extremely high (power-robbing) temperatures, but the intercooler cools the air back down to ambient temperature. Cooler air results in high engine output. A

3 Marine 1,498 cc In-line Four Engine igh-flow fuel injectors with 4 orifices complement the engine s substantial output and contribute to combustion efficiency. Cast pistons with thinner crowns and shallower deck relief match the increased power output. Compression ratio is 8.4:1 as before. Strong exhaust valves offer increased durability. Stem diameter at the head increases from 5.3 mm to 6.3 mm, and a greater portion of the valve (39 mm >> 47 mm) is made from stronger, precipitation-hardened nickel alloy. Large-sized cam chain (4-5 links >> 5-6 links) better handles the increased engine torque. The cam chain tunnel was enlarged to accommodate the larger chain. A shorter water jacket prevents engine oil dilution due to overcooling at low rpm (below 5,000 rpm). Oil cooler features an additional watercooling layer to ensure adequate cooling at higher rpm. Crankcase has a reinforced rib to suit the increased power. Generator flywheel is attached to the crankshaft end using a spline (previously taper) to suit the increased torque. Coupling and damper revised to suit increased power output. The damper has a new shape (6 bulbs >> 8 fins) and the coupling is connected using a larger thread. Intake manifold is formed from plastic, contributing to weight reduction. The ULTRA 300X features a 4-into-2-into-1 powerboat-style exhaust system, which routes the exhaust pipe upwards. This allows the smoothest flow for exhaust gases, maximising exhaust efficiency. Revised internals for the water muffler ensure noise stays at an acceptable level.

4 Propulsion (Jet Pump / Impeller) To efficiently convert the ULTRA 300X s massive power into thrust, a large-diameter 160 mm jet pump is used. Developed based on feedback from Kawasaki s race machines, this pump was specially designed to deliver breathtaking acceleration, stable output and good bite, even when riding in rough water. A large impeller, featuring a sophisticated 3-blade design, delivers both high performance and quiet operation. 8-vane guide smoothes and regulates the flow of water from the impeller for efficient and powerful propulsion. orizontal guide vanes on the grate grip the water, keeping the bow from rising on acceleration for improved stability. The improved hook-up enables a more efficient transfer of power to thrust. Shorter steering nozzle reduces steering load. andling feels lighter than on the ULTRA 260X despite the increased power. ELECTRONIC TROTTLE VALVES & NEW RIDING MODES Electronic throttle valves Kawasaki s first use on a JET SKI efficiently manage the ULTRA 300X s massive power output. They also make minute engine control possible, enabling easy switching between riding modes. Electronic Throttle Valves Accelerator Position Sensor (APS) converts throttle lever input to an electronic signal. This signal is then used by the ECU to control the throttle valves via electric motor. A Throttle Position Sensor (TPS) on the throttle body provides feedback to the ECU. Redundancy in the system (APS and TPS each send two sets of signals to the ECU) ensures some control is maintained in case of failure. The APS is located inside the deck (on the ceiling of the engine compartment, in front of the engine) to ensure adequate protection from water and vibration. The APS and throttle lever are connected via mechanical cable ensuring exposed equipment is sufficiently water resistant. Fuel Economy Assistance Mode Fuel Economy Assistance Mode can be turned on and off by the rider. Activating this mode switches the ECU to a leaner fuel map that prioritises fuel economy over driveability. (Air and fuel injector volume are set for maximum fuel efficiency.) When on, a mark appears on the LCD screen. Fuel Economy Assistance Mode is turned on and off using a button on the top of the left handle. With Fuel Economy Assistance Mode on, fuel efficiency can be increased approximately 15% at 60 km/h. One-touch 5 mph Mode One-touch 5 mph Mode. This handy mode is used in No Wake zones. It regulates engine speed to maintain a forward speed of 5 mph (8 km/h). The mode is activated by pushing the button on the right handle when idling. When activated, a 5 will flash on the speedometer display. To disengage, press the button again, or pull the throttle lever.

5 Electronic Cruise Control This mode fixes speed (rpm) at the level specified. It is a convenient feature for long-distance cruising. The mode is activated by pushing the button on the right handle when riding. Cruising speed can be adjusted using the UP and DOWN buttons. During operation the speed displayed on instrument panel will flash slowly. After activation, the throttle is pulled all the way in to maintain speed. (This position is more relaxing than keeping the lever at partial throttle.) Releasing the throttle lever disengages the system. Economical Riding Indicator Unlike the other riding modes, this handy feature is active all the time. The Economical Riding Indicator appears on the LCD screen to indicate favourable fuel consumption (i.e. at planing speed, when hull resistance is minimal). Paying attention to this indicator can help riders maximise their fuel efficiency. ANDLING & TURNING PERFORMANCE Loaded with technology from Kawasaki s championship winning machines, the race-developed hull handles with precision and stability, with a high level of seaworthiness and at speeds from idle to its impressive top end. Specifically designed to handle the enormous output from the supercharged engine, the hull was completely re-evaluated to ensure the required strength while achieving a lighter package. Features include a new Electric Trim-control System that facilitates the rider s ability to adjust the hull to suit conditions. Lightweight ull Like that of its predecessor (260X), the ULTRA 300X s deep-v hull design enables a high bank angle, motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding. Measuring 22.5, the idealised V-angle at the bottom of the hull helps prevent spinouts during sharp turns. As a result, the ULTRA 300X delivers the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous. Feedback from Kawasaki s numerous IJSBA championship winning racing machines contributed to a hull specially designed to cope with the engine s massive output while offering high stability and responsive handling in both calm and choppy-water conditions. The lower hull is specially designed to distribute the engine and power delivery loads over a wide area. Complete re-evaluation of hull thickness resulted in idealised strength balance and significant weight reduction. Curb mass is now a trim 472 kg. The inside of the bow (below the front storage area) was specifically reinforced to help cope with the increased power output. Bond Flange & Bumper The bottom of the hull slants upwards steeply from the centre section to the bow, allowing the ULTRA 300X to penetrate swells and waves with less shock. At low speeds the result is great stability; at higher speeds the ULTRA 300X s massive thrust enables the hull to push through most waves rather than bounce over top of them. Quattro KSD Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. First seen on the ULTRA 250X, a fourth splash deflector mounted at the top reduces spray during high-speed turns. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimises spray, allowing greater rider concentration.

6 Ride Plate A groove added from the centre to the rear of the ride plate makes it easier to hold a straight course when running straight ahead. Sponsons Sponsons extend from the hull to provide stable straight-line performance (e.g. porpoising from start is minimised, etc) while helping to retain the machine s narrow overall design. They also contribute significantly to the ULTRA 300X s high manoeuvrability when changing direction (particularly at higher speeds). Electric Trim-control System This system allows the angle of the jet pump nozzle to be controlled electrically (step-free adjustment range is ± 8 from STD), making it easier for riders to adjust the attitude of the hull to suit water surface conditions and riding style. In rough water, angling the jet pump upwards raises the bow for rough water handling. Conversely, when conditions are smooth, angling the jet pump downwards lowers the bow for turning performance. FLAGSIP FEATURES As Kawasaki s flagship personal watercraft, the ULTRA 300X needs to look the part. Aggressive new styling, new instrumentation and a host of other features ensure that this JET SKI stands out on the water. Styling The ULTRA 300X gets more aggressive styling care of a redesigned front face with more edged contours. New intake-style design at the bow contributes to the powerful, aggressive image. The front hatch has a flatter design, conveying an image of speed. All-digital Instrumentation All-digital instrumentation makes use of a single, highly legible LCD display. The instrumentation accommodates the new riding modes, as well as a couple of other new functions: external water temperature and air temperature. Clock, Time, Trip, our Meter, Tachometer (digital display or bar graph), Speedometer, Max Speed functions are available as before. Instrument panel position and cockpit visor design were selected to ensure high visibility.

7 5-way Adjustable andle True to its racing roots, the ULTRA 300X includes a 5-way adjustable handle that suits a wide range of riders and riding styles, allowing either stand-up or sit-down riding. The grips are each positioned 20 mm further from the centre to accommodate the new handlebar switches. The wider grip also offers rider-friendly control. Riding Position and Ergonomics Two-piece seat offers roomy accommodation for three people. The relatively narrow seat (now slightly slimmer at the front) is very comfortable for either stand-up or seated riding, as well as for passengers. Ergonomic deck design gives plenty of legroom without necessitating a high seat, for rider-friendly seating accommodations. The reverse lever, located on the left side for easy operation, features ergonomic design (for both the lever itself and the lock-release button) and offers much lighter operation. Lock mechanism for the front hatch was also redesigned, now requiring much less effort to operate. Plenty of Storage The ULTRA 300X offers a total storage capacity of 212 litres. The large-capacity, fully sealed 206-litre storage area has plenty of room for recreational equipment. A detachable storage compartment is also fitted. Mounted on the centre console is a detachable drink holder with space for two drink bottles. Integral with the under-seat rear grip is a compact storage area ideal for tools and other small items. Extensive Cruising Range Offering more fuel capacity than any machine in its class, the ULTRA 300X s fuel tank holds 78 litres of fuel. Kawasaki Smart Steering/SLO-Mode The KSS (Kawasaki Smart Steering) supplementary steering system is designed to assist new riders as they learn turning and manoeuvring of a personal watercraft. Experienced users may not even notice the system at all. Smart Learning Operation (SLO)-Mode function allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace before unleashing the full power of the ULTRA 300X. Two separate keys (one for SLO-mode, one for full-power operation) are provided. ADDITIONAL FEATURES Engine An automatic belt tensioner for the supercharger pulley facilitates belt maintenance. Small power adjustments are easy with the well-designed throttle lever. Even during extended operation the rider s finger does not get tired easily. Immobiliser function incorporated into the ignition switch helps prevent theft. Works with both keys (fullpower and SLO-mode versions). To avoid concentrating heavy components towards the rear, the battery is located inside the front storage area near the centre of the machine. This remote location also frees up space inside the engine bay. ull The ULTRA 300X features a built-in cleaning system to purge seawater used to cool the engine and intercooler. There are two separate circuits (one for the engine, one for the intercooler), each with a dedicated flushing port on the transom. Fitting a separate connecting tube is quick and easy. (Flushing the engine requires the engine to be running; flushing the intercooler requires the engine to be off.
