MIDRANGE
Mechanical or Tiller: 115 hp, 90 hp, 75 hp
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.

90 HP
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.

• Only 353 pounds
• Available in 20” or 25” shafts
• Powerful 35-amp alternator
• Optional Variable Trolling RPM via the Command Link® tachometer

Features may include: 

Power and Efficiency

• Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s EFI optimizes fuel atomization further enhancing fuel economy.

Powerful Hole Shot

• The Composite Intake Manifold on the F115, F90, and F75 feature long tube intake tracks, tuned to increase airflow, which boost low-end and midrange torque. This means a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box, and surge tank reduce air intake noise and air turbulence for smooth, quiet operation.

Optimum Performance

• A TCI microcomputer ignition adjusts timing to maintain optimal engine performance, economy, and power under all operating conditions.

Lightweight, Compact Design

• To keep weight down and efficiency up, the F115 has a double overhead camshaft, and the F90 and F75 feature a single overhead camshaft, but still deploy four valves per cylinder. That setup means less mass in the cylinder head and reduced weight for the overall outboard. At the same time, four valves per cylinder means great engine combustion, which contributes to horsepower, torque and fuel efficiency.

Quick Acceleration

• The F90 and F75 have stepped up to 1.8-liter displacement, joining their F115 big bro. Meanwhile the 90 hp and 75 hp have both dropped 13 pounds. Lighter weight and increased volumetric efficiency, plus increased displacement equals thrilling performance and make our 90 hp a top performer in acceleration and torque.
