DF115B

The new Suzuki outboard engine, the DF115B, features updates that further enhance its overall performance. The compression ratio is now 10.6/1, allowing this over 2-liter outboard engine to further improve top speed and accelerate better while optimizing thermal efficiency.

The fuel efficiency has also been improved compared to the well-known DF115A model among the brand's customers. Tests have shown a 5 to 6% increase in fuel savings for the DF115B across mid to high speed ranges.

The new cowling features a special air intake that optimizes water separation while reducing intake air temperature, enabling higher power delivery 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 enhances spark generation and improves combustion efficiency.

The main difference with its "big brother" DF140B is that it achieves its power over a broader and lower speed range.
