SUZUKI 140 B

The new Suzuki outboard engine, the DF140B, features developments that further enhance its overall performance. The compression ratio is now 10.6/1, allowing this over 2-liter outboard to further improve top speed and achieve better acceleration while optimizing thermal efficiency.

Fuel efficiency has also been improved compared to the well-known DF140A model. Tests have shown a 5 to 6% improvement in fuel consumption for the DF140A across mid to high speed ranges.

The new cowling adopts a special air intake that optimizes water separation while reducing intake air temperature, which enables delivering higher power 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, leading to a better spark generation and improved combustion efficiency.

The main difference with its "little brother" DF115B is that it delivers its power over a higher speed range.
