The Ultimate Choice

We are extremely proud of what we have achieved with the DF300B – an outboard that perfectly balances awesome power and thrust, with outstanding fuel-efficiency and trusted reliability all in a lightweight and stylish design.

Built for every-day use of larger boats, this market-leading new outboard has been engineered to run on 91 RON fuel and, is the world's first four stroke outboard of 300 horsepower with a dual propeller. This high-tech and innovative DF300B has been designed to be robust, easy to use and versatile, making it the ideal outboard for large boats whatever the task.

GEKI: Parting Seas

A Force to Match the Power of Nature and the Sea
Representing Suzuki’s Identity and Heritage
A Symbol of Our Passion and Commitment
to the Ultimate in Marine Innovation

Combining Huge Power and Maximum Efficiency

Our engineers set out to build a compact, lightweight outboard that combines the high power required, alongside the operating efficiencies that cannot be achieved by using technologies such as turbocharging or supercharging. Additionally, they set the goal of making the DF300B run on low octane, 91 RON fuel, which combined with legendary Suzuki reliability makes the outboard ideally suited for a wide variety of large boats around the world.

The traditional single propeller design creates forward thrust, but also produces a significant amount of rotational energy. Our engineers have captured this wasted energy and turned it into productive power by utilising our revolutionary dual-propeller technology. They have solved the problem of the disruption of the water flow, caused by the larger gear case, typically needed by higher power engines. Years of research and innovation have gone into developing the technologies that significantly improve the way an outboard converts engine power into underwater thrust. The result is a revolution in innovation. We call it ‘GEKI’.
