DF115B

Suzuki's new outboard motor, the DF115B, benefits from improvements that further enhance its overall performance. The compression ratio has increased to 10.6/1, allowing this over 2-liter outboard motor to further improve maximum speed and achieve better acceleration while optimizing thermal efficiency.

Energy efficiency has also been improved compared to the well-known DF115A model favored by the brand's customers. Tests have demonstrated a 5 to 6% reduction in fuel consumption for the DF115B across a medium to high speed range.

The new cowling features a special air intake that optimizes water separation while reducing the 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, enabling better spark generation and improving combustion efficiency.

The main difference from its "big brother" DF140B is that it delivers its power over a lower and broader rpm range.
