In a world premier on the opening day of the Genoa International Boat Show, Suzuki has unveiled two new high-performance additions to its existing range of four-stroke outboards.


Suzuki DF150 and DF175

Suzuki's new Big Block DF150 and DF175 are packed with useful refinements.


The new DF175AP and DF150AP use an in-line, four-cylinder DOHC 2.9-litre ‘Big Block’ alongside a high compression ratio for impressive low-end torque and potent acceleration. To further maximise performance, each outboard is equipped with a Semi-Direct Air Intake System to provide the engine with a cooler flow of air, an O₂ Sensor to optimise combustion, and a Knock Sensor for superior reliability.

As regards refinement, Suzuki has employed a Counter Balancer System and Thrust Mount System to achieve smooth engine operation, plus an air intake resonator to help reduce noise. In tandem with these features, Suzuki’s offset drive shaft also moves the outboard’s centre of gravity forward, helping improve balance and reduce vibration on the transom, while also keeping the outboard’s overall dimensions much more compact.

Other notable features include Suzuki Selective Rotation, which allows the same engine to operate in either normal or anticlockwise directions for multiple installations; Suzuki Lean Burn Control for uprated fuel economy over a wide operating range; Suzuki Precision Control for smoother power transitions; and Keyless Start technology, which uses a floating key-fob to transmit a unique access code to the engine’s starting system, reducing the prospect of a lost key and minimising the risk of theft.

Both outboards feature new 3D decals and are available in Pearl Nebular Black (Suzuki’s rather lovely new finish) or Cool White (which looks a bit like an 80s tribute), so you can pick the colour that best suits your boat. But in either case, Mr. Yasuharu Osawa of Suzuki Motor Corporation, is plainly delighted with the new additions: “I must once again pay tribute to our engineers who have delivered more high-end, high-performance outboard motors to enhance our already strong range. I am confident that these new models will be hugely popular right across Europe and will cement Suzuki’s reputation for producing outstanding large horsepower outboards.”
