KAWASAKI 250 X ULTRA JET SKIRELISTED DUE TO NONE PAYING BIDDERThis ski is in absolute mint condition with only 36 hours use and only 13 of those is salt water use, always washed off and completely flushed out after every use, serviced only 10 hours ago with new plugs.This ski is a flying machine and has to be rode to believe the power from a standing start going from 0 to 60mph in under 4sec, will easily pull a skier and i have used it to pull a two man doughnut which it does with absolute ease.I have the owners manual and will consider including life preservers in the sale.Heres a review of the ski.The Ultra 250X’s engine, jet drive and hull incorporate racing technology refined through Kawasaki’s multiple IJSBA championships. This knowledge application allows it to deliver the awesome acceleration of a drag racer, and help ensure excellent hook-up even in rough water.
With a 1,498cc engine derived from Kawasaki’s capable Jet Ski STX-15F watercraft as the foundation, the Ultra 250X produces power comparable to a normally aspirated high-performance three-liter engine. It accomplishes this amazing feat via the addition of a Roots-type supercharger. Unlike centrifugal superchargers or turbochargers, the Ultra 250X’s high-volume direct-drive supercharger delivers boost virtually instantly at any engine speed from idle to redline. This produces a linear, smooth torque curve that is ideal for a personal watercraft that needs to accelerate hard all the way from a standstill to its breath-taking top-end speed.Heat build-up from compressing the intake air is a common drawback of forced-induction. The Ultra 250X uses of a large-capacity intercooler to overcome this handicap. With the 250X’s supercharger compressing the air to a maximum boost pressure of 11.4psi, the intake charge can reach extremely-high temperatures potentially limiting the engine’s power output. However, the 250X’s large-capacity intercooler brings the pressurized air down to ambient temperature or even less –ideal for producing maximum power.
A huge 155mm jet pump featuring the largest PWC impeller and nozzle Kawasaki has ever produced transfers the big power from supercharged 1,498cc engine into the Jet Ski Ultra 250X’s blazing acceleration. Developed based on lessons learned from Kawasaki’s race machines, this pump was designed to deliver predictable thrust and good “traction,” even in rough water.
A significant factor in this extra “traction” are the pump’s eight guide vanes that smooth the flow of water from the impeller for efficient and powerful propulsion. The pump also incorporates a groove from the center to the rear of the ride plate which makes it easier to hold a stable heading for straight line riding. Complimenting the 155mm jet pump is an equally large, sophisticated three-blade impeller that delivers high performance with smooth and quiet operation.Its a beautiful ski and always turns heads when we pulled up at Piel island ( a local island with a pub and castle on it which gets crowded on sunny weekends) and made all the other skis look like vespa’s.comes with the trailer and light board,has had a new tow attachment with security lock, winch is a bit sticky on the ratchet but they can be got on ebay for £25 fully Datatagged for security.Any questions please ask and can be water tested
