Supercharged Excitement
Just ask any drag racer - supercharged is the ultimate path to massive engine power. Supercharging delivers instantaneous throttle response and boost immediately available from idle. In making the JET SKI ULTRA 250X the ultimate personal watercraft, we used a potent direct-drive Roots-type air-pump system that constantly is supercharging the intake mixture. The system pressurises the engine’s inlet tract up to 1.74 times atmospheric pressure - or 11.4 psi. Delivering more air means more oxygen is available for more powerful combustion. But since compressed air builds heat, a massive aluminium intercooler drops the air charge right down to ambient temperature. Now that’s powerful engineering.
Get ready to experience the most powerful, most commanding, and most outrageously fun personal watercraft in history - the all-new JET SKI ULTRA 250X. It’s Kawasaki’s first intercooled and supercharged 1,498cc Marine powerplant and delivers the instantaneous low rpm response of a dragboat that builds up to a class-shattering 250 horsepower* on the top-end. Any questions? They’ll be answered the first time you ride the stunning ULTRA 250X. But we do have one piece of advice before you do. Hang on.
* Measured in PS at the crankshaft under controlled conditions. Actual performance may vary.
