IN-LINE 4 140-70HP
A POWERFUL DESIGN & THE LIGHTEST IN ITS CLASS
Suzuki has once again reinvented the category again with the DF75A. Suzuki’s new generation of four-strokes, the DF75A is a showcase of advancements and achievements – like digital sequential electronic fuel injection, a powerful 2.59:1 final drive ratio, and a zero-maintenance self-adjusting time chain. All of this comes in addition to Suzuki’s Lean Burn Control System, and newer models also sport the optional Suzuki Troll Mode System.
The DF75A hosts digital sequential electronic fuel injection, meaning it reads the electronic control unit monitors throttle setting, engine RPM, cylinder wall and air-intake temperature and atmospheric pressure all at once. All of these considerations cause the fuel injection to enter the combustion chamber at the most optimal opportunity. The benefits are smoother and faster acceleration, crisp throttle response and quick, reliable starting, no matter what the temperature is.
The DF75A 4-stroke outboard is the lightest in its class at 156kg, allowing Suzuki’s mid-range outboard category to a wide array of fishing and family boats. Being the lightest in class, it’s extraordinarily compact yet extremely powerful and exceedingly reliable.
Suzuki outboards are among the most compact outboards in their respective classes.
That’s due in part to our proven offset driveshaft system. This design places the crankshaft in front of the driveshaft through the use of intermediate gear reduction. In addition to providing an increase in power performance and adding to the compactness of the outboard, this system moves the outboard’s centre of gravity forward, resulting in better weight distribution and balance, better directional stability, and less vibration.
The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions.
■ Significant improvement in fuel economy in all speed ranges especially at cruising speed.
■ Fuel use and expense are reduced thanks to improved fuel economy.
2-Stage Gear Reduction
This system which incorporates the Offset Driveshaft features a first stage reduction between the crankshaft and drive shaft and a second stage reduction inside the gear case. This design makes a larger gear ratio possible, allowing it to turn a large diameter propeller for high propulsive efficiency while providing high torque.
■ High propulsive efficiency with large diameter propeller.
■ Powerful navigation, maintaining propeller rotation even with a larger load.
■ Tremendous power to turn large diameter propellers, offering quick acceleration.
Suzuki Easy Start System
The Suzuki easy start system no longer require to hold the key until the engine start. Now simply turn the key and release and the starter will stay engaged until the engine starts.
The system also features more precise cylinder detection, fuel injection, and ignition control to deliver smoother and improved starts, more efficient combustion, and greater fuel economy making the outboard more environmentally friendly.
Streamlined Gear Case and Highly Efficient Propeller
The lower gear case utilises a hydrodynamic design. As the lower unit moves through the water its sleek form reduces drag by up to 36% compared to conventional designs, contributing to faster acceleration and increased speed.
Suzuki's two-stage gear reduction allows the use of a larger diameter propeller. Suzuki engineered a new highly efficient propeller specially for this series that takes advantage of the additional torque available and provides faster acceleration and top speed.
Self-Adjusting Timing Chain
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.
■ Higher durability compared to belt types
Tilt Limit System
A tilt limit system that prevents the outboard from tilting beyond a certain degree.
■ Prevents damage to the boat or outboard due to excessive outboard tilting.
Dual Engine Flush Ports
Over time, salt, sand and dirt build up can restrict flow in the cooling system causing damage. To help prevent such build up, two freshwater flush ports are employed to make flushing the cooling system much easier. With one port located on the port side of the down housing and a second port located on the front panel, you'll always have easy access to the flushing system regardless if the the boat is in our out of the water.
Suzuki Troll Mode System
A system that enables the boat to move at a constant speed.
■ The boat can be moved at a constant speed without operating the throttle.
Suzuki's Anti Corrosion System
Suzuki protects its outboards with an anti-corrosion finish specially developed by Suzuki. Applied directly to the aluminium surface it maximises the bond between the finish and the surface, increasing the protection and durability of parts that are constantly exposed to saltwater.
