Beam: 2 ft. 2 in.
Fuel tank capacity: 5
The SuperJet is powered by a high-performance, 73 horsepower, two-cylinder, 701cc Yamaha marine engine. Two 38mm Mikuni carburetors feed this world-class powerplant, providing excellent throttle response throughout the total RPM range.
Yamaha Loop-charged Combustion: Fuel mixture actually loops as it enters the combustion chamber, which helps distribute fuel/air mixture evenly for better combustion, performance and fuel economy.
Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts.
Electronically Controlled, Variable Ignition Timing: For exact ignition advance control at all throttle positions and RPMs.
The Jet Pump Propulsion System
The SuperJet 144mm Hyper-Flow jet pump propulsion system with three-blade aluminum progressive-pitch impeller is designed to maximize water flow for high performance. The SuperJet pump configuration provides excellent hook-up and smooth acceleration.
Stainless Steel Impeller Housing Liner: For high durability, the liner maintains accurate clearance tolerances between the impeller and the housing.
High Flow Intake Duct and Grate: The dynamic shape of these items directs water flow into the pump for better thrust, performance and hook-up.
Pumps are Manufactured with YDC30: A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection.
The Hull and Deck
The SuperJet Fiberglass Reinforced Plastic (FRP) deck and Sheet Molded Compound (SMC) hull is designed specifically for solo riding. The SuperJet hull is reinforced at critical load bearing areas for durability and strength.
High-performance, Concave Hull: The lightweight, concave hull design of the SuperJet provides superior grip and agility on the tight turns and allows a true feeling of adhesion to the water's surface.
Environmentally-minded Innovations: By employing proven technologies, Yamaha delivers significant reductions in noise levels without compromising performance and reliability. These technologies include:
Yamaha Sound Suppression System: This system of integrated noise reduction components targets the three common types of noise: 1.) intake noise, 2.) exhaust noise and 3.) noise from vibration.
Oval-shaped Handle pole: This handle pole design is 40 percent lighter and 50 percent stronger than conventional handle poles and its high pivot position gives the rider more leverage for easier transitions and turning.
Corrosion Resistant Coil Spring: Makes the handle pole feel lighter for optimal control and reduces rider fatigue.
Thickly Padded Ride Tray: Padding is provided on the deck, gunwales and handle pole for a more comfortable ride.
Kick Step: Provides riders with a slip resistant surface and added balance.
Automatic Bilge System: Removes water from the engine compartment.
Transom Exhaust System: Adds performance while reducing noise levels.
Adjustable Steering System: Allows the rider to adjust the steering nozzle angle and turning performance.
Yamaha's Trademarked Visibility Spout®: A waterspout from the rear of the craft that improves the crafts conspicuity.
