History is about to repeat itself, as Kawasakis new JET SKI® Ultra® 260X reclaims the title as the most powerful production PWC sold in the U.S. Only two years after shattering records with the supercharged and intercooled Ultra 250X, Kawasaki engineers have raised the horsepower stakes even higher with the new Ultra 260X.
Beam: 3 ft. 11 in.
Fuel tank capacity: 21
Max load: 496
Standard features:
• Supercharged and intercooled, 1,498cc, liquid-cooled in-line four-cylinder engine
• Compression ratio raised from 7.8:1 to 8.4:1 via new cast pistons that also feature revised crowns with machine finishing and greater durability
• New higher lift profile cams – the intake increases from 7.8mm to 8.5mm; exhaust, from 7.5mm to 8.2mm – contribute to the increased engine output
• Inconel exhaust valves are fitted for superior heat resistance and enhanced reliability
• 33.4mm intake and 28.3mm exhaust valves
• Ignition timing advanced 4-degrees also contributes to the most powerful production PWC engine in the world
• Water cooling line modified to optimize the cylinder wall temperature. A check valve added to the coolant passage between the cylinder jacket and the water muffler shuts the water flow off at over 2000 rpm, keeping the cooling water inside the cylinder jacket
• Lower crankcase strengthened around the oil-return passage to handle the increased engine output and further increase durability
• Head cover revised for improved appearance Precise power adjustments are easy with a throttle lever that is designed to prevent finger fatigue on longer rides.


• Force-feeds the engine two liters of air with every revolution, providing a stable supply of high-pressure intake air at all rpm
• Produces large amounts of boost even at low rpm, for instant and powerful acceleration right off of 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 11.4psi of boost pressure
• Two different air bypass valves are used to prevent over boosting at low and medium rpm


• Inter-cooler pressure valve setting changed to improve the pressure control
• Efficiently cools the high-pressure intake air
• Cooler air results in higher combustion efficiency and high engine output
• Liquid-cooling allows the intercooler to maintain consistent thermal performance


• High-flow fuel injectors with four orifices are fitted to complement the increased power output and improve combustion efficiency
• Single throttle body features a large 60mm bore diameter


• 4-into-2-into-1 powerboat-style exhaust system routes the exhaust pipe upwards
• Allows the smoothest path for exhaust gases, maximizing exhaust efficiency


• Efficiently converts the Ultra 260X’s massive horsepower into thrust using a large-diameter 155mm jet pump
• Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver stable output and good “bite,” even when riding on rough water
• Revised impeller design features blades with less twist, more efficiently translates the 260X’s increased engine output into increased acceleration performance
• The large, sophisticated three-blade impeller also offers 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 for easy operation

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


• Increased hull rigidity at bow to balance hull performance with increased engine power
• 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 high stability and responsive handling in both calm and rough-water conditions
• The lower hull is specially designed to distribute the engine and power delivery loads over a wide area
• The 260X’s deep-V hull 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
• The idealized 22.5° 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 upwards steeply from the center section to the bow, so the Ultra 260X can penetrate swells and waves with less shock; delivering extreme stability at low speeds and pushing through waves rather than bouncing over them at high speeds
• Battery located inside the front storage area near the center of the machine, avoiding concentrating heavy components at the rear and freeing up space inside the engine bay
• Integrated sponsons extend from the hull, providing stable wallow-free straight-line performance and contributing significantly to the 260X’s excellent high speed maneuverability while helping to retain the narrow hull design


• The Ultra 260X’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 blasting straight ahead, at high speeds or low, the Quattro KSD minimize spray, allowing greater rider concentration


• 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

• Five-way adjustable handlebars allow operation while standing or sitting and suit a wide range of riders
• Relatively narrow seat is comfortable whether riding stand-up, seated or with passengers
• The 2-piece seat, which offers roomy accommodation for three people
• Ergonomic deck design gives plenty of legroom
• A long rear boarding step and dual grab handles makes it easy to climb onboard, and the step retracts inside the bumper to prevent damage
• A quick and easy under hood hose connection allows an easy method to flush sea water out of the engine
• Mirrors are mounted to the upper deck to facilitate opening of the hatch cover


• The ULTRA 260X offers over 60 gallons in total storage capacity – the most in the industry
• The large-capacity, fully sealed 53-gallon storage area with a detachable storage tray has plenty of room for recreational equipment
• Mounted on the center console is a detachable drink holder with space for two drink bottles
• Ideal for small items like a ski rope, a compact storage area is integrated with the under-seat rear grip

• 20.6 gallon fuel tank has more fuel capacity than any machine in its class (1) Horsepower measured in PS at the crankshaft under controlled conditions. Actual performance may vary.
