2011 Kawasaki Jet Ski Ultra 300X

The Jet Ski® Ultra® 300X is just the thing for you power junkies out there. This, the most powerful Jet Ski ever built, packs 300 horsepower¹ and its deep-V hull offers both stability and cornering performance. Not only is the 300X a great performer, but it also packs the things you need thanks to its 54-gallon storage bin under the front cowl.

As befits Kawasaki’s top-shelf performer, the Ultra 300X has been thoroughly redesigned for 2011, from nose to jet pump and everything in between. Power and thrust are key ingredients in the Ultra 300X package, and the thoroughly massaged, 1,498cc inline-four DOHC engine supports that recipe like no other. The big news for 2011 is the use of an all-new supercharger, one that’s two steps beyond the abilities of the roots-type unit fitted to previous X-model Jet Ski watercraft. Roots-type superchargers are known as fixed-displacement units, which produce large quantities of boost at all rpm levels, even right off idle, for a flat torque curve and usable, step-free power across the rev range.

Besides the all-new and high-tech supercharger, there’s new technology in the form of Kawasaki’s Electronic Throttle Valve system. Thanks to this system, the 300X boasts a range of riding modes, including the Smart Learning Operation mode, which allows newer riders to become familiar with the 300X at a more relaxed pace. This is done via separate keys that dictate power to the ECU.

Hard to believe, but revised ergonomics improve comfort significantly over the already plush 260X. The handlebar remains five-way adjustable to fit a range of riders and riding styles, with grips positioned nearly an inch wider to accommodate all-new handlebar switch assemblies.

2011 JET SKI® ULTRA® 300X

Jet Ski® performance has been taken to a whole new level with the Jet Ski Ultra 300X watercraft, boasting the most powerful engine ever in a Jet Ski PWC- to the tune of 300 horsepower. The 300X has been completely redesigned for 2011, from nose to jet pump and everything in between, to provide a lightweight, powerful, agile and comfortable Jet Ski that sits proudly atop the watercraft pyramid.

REDESIGNED FIBERGLASS-REINFORCED HULL

The race-derived, fiberglass-reinforced hull has also been redesigned for 2011 to enhance strength and achieve weight savings where possible. Hull thickness was reduced and combined with special reinforcements in the inside bow area. This results in a lighter, stronger, more maneuverable and more stable hull.

PLUSH, COMFORTABLE SEATING

The two-piece seat offers roomy accommodations for up to three people. A slightly narrower seat at the front makes it easier to ride sitting or standing. The ergonomic deck design gives all riders plenty of legroom for plenty of comfort.

STRONGER, LIGHTER HULL DESIGN

Feedback from Kawasaki’s IJSBA championship-winning racing machines integrated into design enables it to cope with the engine’s increased power. The lower hull is specially designed to distribute the engine and power delivery loads over a wide area. To help prevent unwanted spinouts during sharp turns, Kawasaki engineers designed a 22.5-degree V-angle at the bottom of the hull.

STABILITY IN ROUGH WATER

A complete re-evaluation of the hull thickness resulted in optimum strength balance and a significant weight reduction. This offers a combination of high stability and responsive handling in both calm and rough-water conditions. The bottom of the hull slants upward steeply from the center section of the bow, so the Ultra 300X can penetrate swells and waves with less shock, delivering extreme stability at low speeds. This also allows the Ultra 300X to push through waves rather than bounce over them at high speeds.

CLASS-SHATTERING 300-HORSEPOWER ENGINE

The most powerful engine ever fitted to a Jet Ski watercraft, the Ultra 300X makes use of an all-new supercharger, one that’s beyond the abilities of the roots-type unit fitted to previous X-model Jet Ski watercraft. It produces large quantities of boost at all rpm for a flat torque curve and usable, step-free power across the rev range.

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 stable supply of high-pressure intake air at all rpm
Planetary gearing increases supercharger speed by a factor of 2 for better response
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 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 17 psi of boost pressure
Two different air bypass valves are used to prevent over boosting at low and medium rpm
