🔍 Model Background

The Suzuki 115 HP 4-stroke outboard (2021–2024), part of the advanced DF115BG series, introduced drive-by-wire technology to the mid-horsepower market—offering smooth digital throttle and shift, improved performance, and increased fuel efficiency.

Powered by a lightweight 4-cylinder DOHC engine with multi-point electronic fuel injection and Suzuki’s signature Lean Burn Control System, the 115 HP model delivers strong low- and midrange torque, ultra-quiet operation, and outstanding fuel economy. The newly redesigned engine cowling and gearcase further improve airflow and hydrodynamic efficiency.

The DF115BG offers full compatibility with digital gauge systems, precision control levers, and Suzuki’s multifunction displays, giving boaters a seamless user experience. Maintenance has also been simplified with better service access and corrosion-resistant materials for extended durability in saltwater environments.

Produced from 2021 through 2024, the Suzuki 115 HP DF115BG stands out as a modern, fuel-efficient choice for boaters who value digital integration, smooth power delivery, and advanced 4-stroke reliability.
