MIDRANGE

The sun glints off the water as you head down to the dock for a day with family and friends. Whether you’re trolling for sand bass or towing a skier, Yamaha’s Midrange outboards are ready to fuel the fun. Built to be fast, light and powerful, they’re perfect for mid-sized craft like deck or multispecies boats, and select models offer a 25” shaft option for added versatility. Go ahead and take off for the day with Yamaha’s Midrange 115, 90 and 75 hp outboards.

The all-new 1.8-liter Midrange F90 features greater displacement and a single-overhead-camshaft design with four valves per cylinder. This boosts power and volumetric efficiency, streamlines design, and makes the F90 a leader in torque and acceleration.

Features may include:

  • Only 353 pounds
  • Available in 20” or 25” shafts
