Introduction of new technologies including the contra-rotating propellers

Suzuki Motor Corporation has unveiled the DF350A flagship outboard, which has realised horsepower of 350HP, the maximum output in Suzuki’s lineup of outboards.

For the first time on Suzuki outboards, DF350A adopts the contra-rotating propellers called the Suzuki Dual Prop System. In this system, two propellers efficiently transmit forward thrust, enhancing acceleration and directional stability. In addition to high compression ratio, the newly-developed 4-stroke V6-cylinder engine is equipped with features such as the Direct Intake System to realise superb output performance and high fuel efficiency.

At the unveiling event held in Miami, US on 9 June, Toshihiro Suzuki, President, Suzuki Motor Corporation said “Outboards play important role in Suzuki’s business, and DF350A is a model that clearly illustrates our brand slogan The Ultimate 4-Stroke Outboard.”

DF350A will be produced at the Toyokawa Plant in Japan, and launched in the US from July. Subsequently, they will be launched globally including Japan and Europe.
