DF115B - Stealth Line

The new Suzuki outboard motor, the DF115B, features updates that further improve its overall performance. The compression ratio is now 10.6/1, which allows this engine of over 2 liters to further enhance top speed and achieve better acceleration while optimizing thermal efficiency.

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 medium to high speed ranges.

The new cowl features a special air inlet that optimizes water separation while reducing intake air temperature, enabling higher power output at mid-range speeds. A resonator system further reduces engine noise at all speeds.

The new direct ignition reduces the number of parts and wiring, leading to a better spark generation and improved combustion efficiency.

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