|Suzuki puts fresh spin on outboards|

Suzuki Selective Rotation achieves a first for outboard motors by unifying both regular and counter-rotation operations into a single model.
When installing two or more outboards to the transom of a boat, a combination of regular rotation and counter-rotation units is normally used, which currently means using two separate outboard models – a regular rotation model and a counter-rotation model. However, Suzuki Selective Rotation means that one outboard model can operate in either regular or counter rotation modes.
The technology will first be introduced on the new DF300AP. In its standard form, this new model will operate in regular clockwise rotation, using the forward gear. By changing the gear-shift mode and adding a counter-rotational propeller, the same outboard can operate anti-clockwise.
In counter-rotation mode, power is transmitted through the reverse gear, which has been upgraded and improved to give it the same characteristics as the forward gears. The specifications and materials used for both forward and reverse gears have been optimised, as well as improving the layout of the bearings. In redesigning the gear case to accommodate the new gear system, the Suzuki engineers have also taken the opportunity to add more new features to the new DF300AP.
Using accumulated fluid analysis technology, the new gear case provides reduced resistance and improved durability. At the same time, a structural analysis has been carried out to optimise each component. Moreover, the new DF300AP features two water intakes on each side of the gear case – the current DF300 has just one on each side. The additional water intakes ensure stable cooling performance at high speeds or in shallow water.
