115 - 30 hp Midrange F90

The all-new 1.8-liter I-4 F90 features greater displacement and a single-overhead-camshaft design with four valves per cylinder. This boosts power and volumetric efficiency and streamlines design. In fact, it's 13 pounds lighter than previous designs. A lighter, more powerful design gives the F90 blistering speed that's 1.5 mph faster than competing outboards.
