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.

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.”
