The new Suzuki outboard motor, the DF115B, features enhancements that further improve its overall performance. The compression ratio has increased to 10.6/1, allowing this over 2-liter outboard to further increase top speed and improve acceleration while optimizing thermal efficiency.
Fuel efficiency has also been improved compared to the well-known DF115A model. Testing has shown a 5 to 6% reduction in fuel consumption for the DF115B at medium to high speeds.
The new cowling adopts a special air intake that optimizes water separation while reducing intake air temperature, enabling higher power output at intermediate speeds. A resonator system further reduces engine noise at all speeds.
The new direct ignition reduces the number of parts and wiring, which allows for better ignition spark and improved combustion efficiency.
The main difference with its "big brother" DF140B is that it delivers its power over a lower and wider speed range.
