New Kawasaki 2017 ULTRA 310X for sale in Cairns

2017 ULTRA 310X

The Fastest Jet Ski on the Planet Just Got Faster!

Personal watercraft (PWC) innovators for four decades, Kawasaki surprised the entire industry when it debuted the Jet Ski Ultra 300X watercraft. Now a substantially improved Jet Ski, Ultra 310X watercraft, raises the PWC stakes before the competition has even had a chance to place a 300 class bet!

With incredible boost from an Eaton Twin Vortices Supercharger, the big Kawasaki Ninja-inspired marine engine pumps out 310 horsepower* through the pump for incredible hook-up and acceleration. Not only is the Ultra 310X high powered, but it's also high-tech. Riders can adjust hull attitude with the electric trim system, there's an electronic throttle valve with electronic cruise control, fuel saving ECO mode and an all digital instrument panel.

2017 ULTRA 310X 310 Horsepower Supercharged Engine

310 Horsepower Supercharged Engine

1,498cc, liquid-cooled inline four-cylinder engine makes 10 additional horsepower through reduced mechanical loss, improved efficiency. The Eaton TVS constant-displacement supercharger and liquid-cooled intercooler provide instant and consistent boost for outstanding performance throughout the rev range.

  • Heat-resistant plastic intake manifold is reshaped for improved low-mid range power
  • The cast pistons feature additional ring land V-grooves for better oil retention
  • Hardened nickel 33.4mm intake and 28.3mm exhaust valves offer superior reliability
  • Two-layer oil cooler offers efficient cooling
  • Large cam chain increases reliability in a supercharged engine application
  • Reinforced crankcase adds to engine’s durability and reliability
  • Fuel pump provides a high pressure, high flow fuel for increased power and better fuel efficiency.
  • Thick water jackets improve cooling performance
  • Check valve system between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, to keep the cooling water inside the cylinder jacket for optimum cooling performance
  • Piston cooling oil jets increased from one jet per piston to two jets per piston for increased piston cooling
  • Oil pan features additional baffle plates to prevent oil slosh during tight turns or extreme acceleration/deceleration
  • Crankcase oil return holes are designed for quicker oil return to the oil pan

2017 ULTRA 310X Strong, Light Hull Design - Superb in Calm and Rough Water

Strong, Light Hull Design - Superb in Calm and Rough Water

The reinforced inner bow is extremely light with ample strength to handle the engine’s power output. Exemplary straight-line tracking and responsive handling in both calm and rough-water conditions set performance benchmarks for the class. The lower hull is specially designed to distribute the engine and power delivery loads over a wide area.

Deep-V hull design enables a steep bank angle for motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding. The 22.5° V-angle at the bottom of the hull helps reduce unwanted spinouts during sharp turns. This all assists in delivering the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous.

The bottom of the hull slants upward steeply from the centre section to the bow, so the 310X can penetrate swells and waves with less shock, pushing through waves rather than bouncing over them at high speeds. Integrated sponsons extend from the hull, providing wallow-free straight-line performance and contributing significantly to the 310X’s excellent manoeuvrability while helping to retain the narrow hull design.

2017 ULTRA 310X Comfort and Convenience

Comfort and Convenience

Roomy three-passenger seat offers ample support plus all-day comfort whether riding stand-up solo, seated or with passengers. The passenger handrail on the Ultra 310X is located to a more ergo-friendly location to help reduce passenger fatigue and features a redesigned handle for better grip. The optimally curved mirrors have been designed for a wider rear view and are mounted to the upper deck via new brackets

An ergonomic deck design gives plenty of legroom and the left-side reverse lever is ergonomically designed for easy operation. At the end of the day on the water a quick and easy hose connection allows a simple method to flush sea water out of the engine.
