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.
Meet the Lineup
115 HP
Our 1.8-liter Midrange F115 features a double overhead camshaft with four valves per cylinder. This increases volumetric efficiency and gives the F115 a competitive power to weight.
- Only 377 pounds
- Available in 20” or 25” shafts
- Powerful 35-amp alternator
- Optional Variable Trolling RPM via the Command Link® tachometer
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
75 HP
The 1.8-liter Midrange F75 features a step up in displacement from its previous design. Still, its single-overhead-camshaft with four valves per cylinder keeps it compact and shaves off 13 pounds. Bigger power plus lighter weight equals one thrilling new outboard.
- Only 353 pounds
- 20” shaft
- Powerful 35-amp alternator
- Optional Variable Trolling RPM via gauge

IMPRESSIVE TORQUE &
ACCELERATION
The all-new F90 and F75 Midrange outboards have stepped up to 1.8L displacement and now feature a Single Overhead Camshaft, with four valves per cylinder. That makes them both 13 pounds lighter, and our 90 hp a top performer in both torque and acceleration.
Features & Benefits
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.
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.
A TCI microcomputer ignition adjusts timing to maintain optimal engine performance, economy, and power under all operating conditions.
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.
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.
The F115 and all-new F90 and F75 are compatible with Yamaha’s award winning Multi-Function Tiller Handle. It incorporates engine start/stop, emergency stop, gear shift, power trim and tilt operation, variable trolling switch, warning and controls all in one.
The F115, F90 and F75 feature three-phase alternators that produce up to 35 amps of power. For the 90 and 75 hp, that’s 40 percent more output than previous designs, and for the 115, it’s more than 45 percent more charging power. That’s plenty of electrical power for battery charging and accessories, with more to spare.
The F115, F90 and F75 feature Yamaha’s Variable Trolling RPM Switch (VTS®). This allows for precision adjustment of trolling speeds in 50-RPM increments, from 650 to 900 RPM for the 115 hp, and 550 to 1000 RPM for the 90 and 75 hp. It even allows for sub-idle trolling. This is a major plus for anglers.
A Freshwater Flush Device allows you to flush the engine without starting it, for maximum convenience, durability and engine life.
