SUZUKI has announced the introduction of Suzuki Selective Rotation in its DF300AP outboard.
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.
Suzuki’s Selective Rotation means that one outboard model can operate in either regular or counter rotation modes.
For those not familiar with the reason for a counter rotating model the reasoning is simple. In most applications when a boat requires twin engines to power and push it, the port side engine must use a counter rotation lower unit (often referred to just as gearbox) and the starboard engine uses a normal clockwise rotation lower unit. In a twin engine application this must be done so that the propellers are spinning in different directions.
The result is, according to Suzuki, less “dirty” water being drawn from each propeller causing ventilation (air around the blade area); it reduces the tendency for a boat to list to the starboard; and it enables larger boats to manoeuvre at low speed for docking.
The new Suzuki DF300AP is the first outboard or stern drive leg in the world which can operate in either forward (clockwise) or reverse (anti clockwise) direction. This type of lower unit will eventually be available in smaller horse power models in the future.
The DF300AP will be available in Australia and New Zealand in March 2012.
