World's First Drive By Wire 115hp/140hp 4-stroke outboard

Suzuki Marine is globally recognised for making advanced technology and features available to boaters of all types - not just those who run the largest, highest-horsepower outboards. This tradition continues with the intorduction of Suzuki's new-for-2021 DF115BG and DF140BG 4-stroke outboards, the first in their class to offer all the advantages of drive-by-wire technology.

By bringing its proven drive-by-wire technology to its 115HP and 140HP in-line four-cylinder models, 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. 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.

Drive By Wire
Operation from the remote control is delivered to the outboard via an electric signal instead of the traditional mechanical control cable design.


■ Smooth Shift & Operation.
■ Easy Rigging.
■ Increased Fuel Efficiency.
■ Luxury Remote Control.
High Compression Ratio
To achieve the optimised mask, port and piston combination, the shape of parts was simulated over 1,000 combinations and then tested thoroughly with the carefully selected parts.


■ Achieved 10.6 Compression Ratio which contributes to high torque.
Easy Maintenance
Specially designed to be easy for owners to perform maintenance tasks.


Easy access oil filter:
■ Can be replaced simply by removing the top cover.

Oil Spill Catcher:
■ A tray is added around the oil filter to catch oil which comes out when exchanging the oil filter

Oil Level Gauge:
■ Able to use Φ15 oil changer hose
