Showcasing Suzuki’s advanced technologies and designs, Suzuki’sf lagship DF300 outboard has been recognized twice as the most innovative outboard in the industry. The original DF300 was launched as the world’s first 220.7kW (300PS) 4-stroke outboard and was acknowledged for this by the National Marine Manufacturers Association (NMMA) with its 2006 Innovation Award.
The new 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 recognized once again with the 2012 NMMA Innovation Award. 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.
The addition of Suzuki’s Lean Burn Control technology as well as a new Oxygen (O2) Feedback Control System provide boaters with a dramatic improvement in fuel economy as well as environmental friendly operation, further enhancing the overall performance and value of the DF300, Suzuki’s flagship outboard motor. Initial tests show the new DF300 to be 14% more economical than the previous DF300 without sacrificing on any of the power for which the original model was already famous. In essence – the best is about to get a whole lot better!
4.0-liter V6 engine features a 24-valve double overhead cam and VVT (Variable Valve Timing) to deliver plenty of power and torque.
New lower unit features the Suzuki Selective Rotation System which integrates both regular and counter-rotation gears allowing the engine to be programmed to operate in either direction.
Suzuki’s Precision Control (Electronic Throttle and Shift System) offers smooth and positive gear operation.
Suzuki’s Lean Burn Control system allows engine operation on a leaner, more efficient fuel mixture and delivers its benefits over a wide operating range. Combined with Suzuki Precision Control it delivers remarkable fuel economy over a wide operating range.
An O2 Sensor Feedback Control system controls the air to fuel ratio across the engine’s entire operating range optimizing fuel consumption for cleaner, more stable emissions.
Two-way water inlet increases water flow for greater cooling efficiency and shallow water operation.
Suzuki Troll Mode system offers finer control over engine speed at low rpms and is optionally available.

The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions
The system is controlled by hydraulic pressure from the oil pump and the process happens automatically so all you have to do is enjoy the power and performance.
Function for selecting regular or counter rotation on one outboard with an optional connector.
Operation from the remote control is delivered to outboard via an electric signal and not by the traditional mechanical control cables.
A large reduction gear ratio leads to powerful torque for quick acceleration and great top-end speed.
The timing chain runs in an oil-bath so it never needs lubricating, and is equipped with an automatic hydraulic tensioner so it remains properly adjusted at all times.
It helps protect the engine from water in the fuel using a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel.
