Designed for the modern boater
Suzuki Lean Burn Control System
This system predicts fuel needs according to operating conditions allowing the engine to run on a more efficient fuel mixture through the use of a lean air to fuel ratio. Its benefits are delivered over a wide operating range providing significant improvements in fuel economy from low-speed operation up into the cruising range. In-house testing shows that while cruising, the new DF140A is 14% more economical than its predecessor without sacrificing any of the original DF140’s power.
O2 Sensor Feedback Control System
An O2 Sensor Feedback Control system keeps emissions cleaner and more stable by controlling the air to fuel ratio across each of the engine’s operating ranges, the system helps maintain optimum engine operating efficiency across the engine’s full operating range.
Optimised DOHC 4-Valve Engine
Optimised DOHC 4-Valve EngineSuzuki engineers have designed an in-line four cylinder engine that delivers high power output, high performance, excellent fuel economy, and efficient operation. With a displacement of 2,044cm3, the in-line four-cylinder block is topped with a high performance 16-valve, dual overhead cam (DOHC) powerhead.
Suzuki Water Detecting System
Suzuki Water Detecting SystemWater in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilising a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel. The filter also designed to let you check for water visually.
Multi-Point Sequential Electronic Fuel Injection
Multi-Point Sequential Electronic Fuel InjectionSuzuki's electronic fuel injection system makes use of the latest technology and computer control. The system's electronic control unit monitors throttle setting, engine RPM, cylinder wall and air-intake temperature and atmospheric pressure. It then automatically calculates the optimum amount of fuel to be injected into the combustion chamber at the exact time. The benefit is smoother and faster acceleration, crisp throttle response, maximum fuel economy and quick, reliable starting no matter what the temperature.
Suzuki's digital multi point sequential EFI represents the ultimate in outboard efficiency and is found on all Suzuki outboards from the DF40 to the DF350.
Large Reduction Gear Ratio (Powerful Propulsion)
Large Reduction Gear Ratio (Powerful Propulsion)Suzuki’s sophisticated technologies below to acquire a large reduction gear ratio.
■ Offset Driveshaft
The Offset Driveshaft allows Suzuki to make engines smaller by moving the outboard’s centre of gravity forward, while improving weight distribution, power output, balance and reducing vibration.
■ 2-Stage Gear Reduction
These outboards also incorporate 2-Stage Gear Reduction designed to acquire a large reduction gear ratio - it delivers powerful torque for quick acceleration.
Trim and Tilt Limit System
Trim and Tilt Limit SystemThe trim and tilt limit system is designed to help protect the boat from damage that can occur when tilting the outboard. A tilt angle sensor performs as both a tilt limit and trim sender and a step free, continuous type tilt limiter makes installation of the outboard possible on nearly any type of boat.
Suzuki Troll Mode System (Optional)
Suzuki Troll Mode System (Optional)This system provides finer control over engine speed at low rpms keeping the boat moving at a steady speed while trolling. When the system is engaged, the engine speed can be controlled with a Troll mode switch or a Suzuki Multi-Function Gauge. That adjusts engine revs in 50rpm increments over a range that spans from idle to 1,200rpm.
Suzuki Anti Corrosion Finish
Suzuki Anti Corrosion FinishSuzuki’s Anti Corrosion Finish is specially formulated to increase the durability of the engine and help protect parts of the outboard’s aluminium exterior. This advanced finish is designed for maximum bonding of the finish to the outboard’s aluminium surface, creating an effective treatment against corrosion.
Knock SensorFound on some V6 models, this system is used to detect and control abnormal combustion allowing the engine to operate at optimum performance. The system increases engine durability and helps deliver maximum power.
