The new Suzuki outboard engine, the DF115B, features upgrades that further improve its overall performance. The compression ratio is increased to 10.6:1, allowing this over 2-liter outboard to further enhance top speed and achieve better acceleration while optimizing thermal efficiency.
The fuel efficiency has also been improved compared to the well-known DF115A model. Tests have shown a 5 to 6% reduction in fuel consumption for the DF115B across mid to high speed ranges.
The new cowling incorporates a special air intake that optimizes water separation while reducing the intake air temperature, resulting in higher power output at intermediate speeds. A resonator system further reduces engine noise at all speeds.
The new direct ignition system reduces the number of parts and wiring, which improves spark generation and enhances combustion efficiency.
The main difference with its "big brother" DF140B is that it delivers its power over a lower and broader speed range.
