The World’s First Selective Rotation Outboard

Showcasing Suzuki’s advanced technologies and designs, Suzuki’s flagship DF300 outboard has been recognised twice as the most innovative outboard in the industry. The original DF300 was launched as the world’s first 300HP 4-stroke outboard and was acknowledged for this by the National Marine Manufacturers Association (NMMA) with its 2006 Innovation Award.

The latest generation DF300AP incorporates several new features, the most notable being Suzuki Selective Rotation. By strengthening the lower unit’s forward and reverse gearing, Suzuki engineers have designed a lower unit for the DF300AP that will run in either right or left rotation. With this world’s first feature, the DF300AP was recognised once again with the 2012 NMMA Innovation Award. The DF250AP is based on the DF300AP and shares the same award winning innovations and designs of Suzuki’s flagship outboard. Advanced features like Suzuki Selective Rotation, Suzuki Precision Control, and Suzuki Lean Burn Control, plus big V6 power combine to provide boaters with outstanding performance and great convenience.

Suzuki Selective Rotation

In multi-outboard installations on large boats, a counterrotation outboard is usually paired with a regular rotation model to help keep the boat traveling on an even keel and in a straight line. The DF300AP/250AP is built with special counter rotating gearing in the lower unit, which causes the prop to rotate in the opposite direction. Suzuki Selective Rotation eliminates the need to purchase a dedicated counter-rotation outboard by using a special switch that when connected to a circuit inside of the engine compartment, turns a regular rotation outboard into a counter-rotation model with a counter rotational propeller. This industry first is made possible through a special, unified design of gears, shaft, and bearings in the lower unit that are designed to operate reliably and efficiently in either regular or counter-rotation directions

New Lower Unit

Compared to the original DF300, the biggest changes you’ll find on these outboards are in the lower unit, which was redesigned for the Suzuki Selective Rotation system—the world’s first integration of regular and counter-rotation models into a single unit. The system consists of a new drive gear layout in the lower unit that allows the outboard to operate in either regular or counter-rotation mode, and a switch that connects to a circuit in the engine compartment that engages the counter-rotation mode. Like the DF300, the new DF300AP/250AP utilises an aggressive final drive ratio of 2.08:1 allowing it to turn a 406mm (16-inch) diameter propeller available in various pitch size for optimum performance on a wide variety of boats. Changes to gear designs provide greater durability, and adding a two-way water inlet changes water flow into the cooling system for increased cooling efficiency.

3 + 3 years Recreational Warranty

All recreational/privately registered Suzuki Outboards come standard with 3-years / unlimited hours manufacturer’s warranty. Recreational outboards are also eligible for a bonus 3-year Warranty providing that an authorised Suzuki Marine Dealership completes servicing as per the owners manual schedule. The Suzuki dealer must use only genuine parts and oils during both manufacturer’s and bonus warranty periods.
