High-performance 2-stroke engine
The legendary SuperJet is powered by a high-performance, two-cylinder, 701cc Yamaha engine. Two 38mm Mikuni® carburretors feed this world-class power plant, for excellent throttle response throughout the RPM range. Loop-charged combustion distributes the fuel/air mixture more evenly, for better combustion, performance and fuel economy.
Lightweight, deep-strake hull with wide front section
Perfectly balanced to give ultra-tight cornering ability and to maximise its blistering straight-line speeds, the SuperJet's lightweight, deep-strake hull features moulded-in sponsons. Positioned well forward, they increase the wetted surface area, allowing you to turn easily, while giving the SuperJet great stability.
Optimised intake duct pump and ride-plate position
To increase dynamic stability and straight-line running performance within the limited space of the hull, the ride plate is positioned far aft – effectively lengthening the waterline. The pump itself is also positioned far aft, providing stable pump performance even in choppy water.
Hyper-Flow jet pump and adjustable steering nozzle
The SuperJet 144mm Hyper-Flow jet pump propulsion system is designed to maximise water flow for high performance. The SuperJet pump configuration provides excellent hook-up and smooth acceleration.
Race-developed stainless steel impeller
The SuperJet's stainless steel impeller was developed with the feedback from racers. Fluid analysis technology was used to realise its super-efficient, high-performance design – a design that's world famous for delivering superior acceleration and speed.
Spring-assisted steering pole
The spring assisted steering pole and handlebars have been specially designed to provide a riding position that allows you to get the most out of the SuperJet – a machine built for winning. The result is the forward-leaning riding position so popular with pro racers and which offers the ideal, most comfortable stance for competition.
