DF250AP 4-stroke
Designed to Deliver
Showcasing Suzuki’s advanced technologies and designs, Suzuki’s flagship DF250AP outboard has been recognized twice as the most innovative outboard in the industry. The original DF250AP 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 DF250AP 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 DF250AP that will run in either right or left rotation.

With this world’s first feature, the DF250AP 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 DF250AP, Suzuki’s flagship outboard motor. Initial tests show the new DF250AP to be 14% more economical than the previous DF250AP 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!
Features
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
