Yamaha Marine Super Jet - Personal Water Craft Boat

2011 Yamaha Marine Super Jet Standard Features

The Powerplant

The SuperJet is powered by a high-performance, 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:
The new three-blade stainless steel 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.
