First 4-Stroke 140 Horsepower Outboards in the World* to Offer Drive-by-Wire Technology!
Suzuki Motor Corporation has unveiled new DF140BG outboards, the first 4-stroke 140 horsepower outboards in the world* to offer drive-by-wire throttle and shift.
While 140 horsepower outboards are mainly installed on mid-sized pleasure boats, there are rising needs of customers who wish to have the same advanced technologies of high-power outboards installed on large-sized boats.
Hence, the DF140BG have adopted the drive-by-wire throttle and shift control technology called the Suzuki Precision Control, which are installed on Suzuki’s large-sized outboards ranging from 150 to 350 horsepower. This control system replaces the conventional mechanical cable with electrical wires to realize smooth and secure shifting as well as swift and precise throttle control. The reliability and precision control of Suzuki’s drive-by-wire technology has been proven for years on Suzuki’s popular 150HP through 350HP models.
In short, these are the main Features of DF140BG
- First 4-stroke 140 horsepower outboards in the world* to offer drive-by-wire throttle and shift system called the Suzuki Precision Control.
- Upgraded compression ratio from tried and tested 2,045cm3 four-cylinder 4-stroke engine of DF140A series to realize enhanced output characteristic and fuel efficiency.
- Redesigned cowling design which incorporates new air intake structure with enhanced intake performance.
- Oil filter position has been reviewed, which makes it possible to replace the oil filter simply by removing the upper engine cover for easier maintenance.
*Based on Suzuki research as of June 2020.

Suzuki is providing simplified rigging for a wide range of boat builders, along with silky smooth shifting, instant throttle response, enhanced performance and superior fuel efficiency. Combined with Lean Burn Control System, their fuel efficiency has been enhanced in a wide range of speeds.
Enhancements to Suzuki’s new DF140BG go far beyond the integration of drive-by-wire technology. An upgraded compression ratio of 10.6:1 helps these new 2.0-liter displacement outboards achieve better top speed and acceleration by improving thermal efficiency. Fuel efficiency has also been increased as compared to Suzuki’s existing DF140A models. Tests have demonstrated as much as 5% to 7% better for the DF140BG across mid-range to high-end cruising speeds.
Other improvements include a 40 amp alternator that delivers improved output and better charging performance at low idle speeds – ideal for today’s power-hungry fishing boats that spend a lot of time trolling.
While much has changed under the cowl, some enhancements to the new DF140BG are obvious to the eye. The engine itself features a sporty, streamlined exterior design that looks great on centre consoles, flats skiffs, pontoon boats, bass boats and more. With 20-inch (L) and 25-inch (X) shaft lengths available, the new DF140BG outboards are an ideal power choice for a wide range of fresh and saltwater boats. The new outboards boast new graphics and are available in Suzuki Pearl Nebular Black and new-for-2021 Super Cool White color schemes.
The redesigned cowl also incorporates a new air intake structure with improved water separation and a silencer-resonator system to attenuate engine sounds and provide a pleasant boating experience at all engine speeds/RPM.
To make routine maintenance easier, Suzuki made it possible to replace the oil filter simply by removing the upper engine cover. A new Oil Spill Catcher surrounding the oil filter mount allows for changing the filter without making a mess. Suzuki also added an easy access Water Detection Fuel Filter to help protect the engine against contaminated fuel.
“We are pleased to bring new technology and performance to this important class of outboard motor,” said Tanja Maes, Sales & Marketing Marine Manager for Suzuki Marine Southern Africa. “These are not only the world’s first 4-stroke outboards in their class to include factory drive-by-wire technology, they feature a new design, a new look and enhanced performance for a wide range of boats around the world.”
Lean Burn control system
Suzuki’s Lean Burn Fuel Control Technology predicts fuel needs according to operating conditions, then delivers the optimum fuel/air mixture to the engine resulting in greater fuel economy.
Offset drive shaft
The offset drive allows us to make our outboard engines smaller by moving the outboards centre of gravity forward, improving weight distribution, power output, balance and reduces vibration.
Self-adjusting timing chain
Simple, effective and maintenance free timing chain that runs in an oil-bath so it never needs lubricating and equipped with a hydraulic tensioner so it remains properly adjusted at all times.
O2 sensor feedback system
The O2 Sensor Feedback Control system helps maintain optimum engine operating efficiency across the engine’s full operating range.

TECHNOLOGIES
LEAN BURN
The Lean Burn Control System supplies the right fuel and air mixture depending on the navigation conditions.
ADVANTAGE:
- Significant improvement in fuel economy in all speed ranges especially at cruising speed.
- Fuel is saved and gasoline costs are cut thanks to improved fuel economy.
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.
ADVANTAGE:
- More durability compared to belt types of same class.
- Maintenance-free.
SUZUKI WATER DETECTING SYSTEM
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.
ADVANTAGE:
- Can avoid water in fuel, which can lead to issues like poor combustion, lower power output and corrosion.
