2019 Yamaha F90B - 20 in. Shaft
Yamaha has reinvented its versatile F90 outboard to make it even lighter and more compact for greater torque and stronger acceleration. Now the strongest 90-hp outboard money can buy, the new F90 is a great choice for a variety of boats.
Light And Powerful: To keep weight down and efficiency up, the F90 features a single overhead camshaft that deploys four valves per cylinder, which transfers air quickly and facilitates excellent engine response.
Precise Trolling Control: Use the Variable Trolling Speed (VTS) switch to adjust speed in 50-rpm increments simply by pushing a button on the multi-function tiller handle. VTS also functions with Command Link gauges.
Optional Tiller Handle: Yamaha's award-winning Multi-Function Tiller Handle incorporates engine start/stop, emergency stop, gear shift, power trim and tilt operation, variable trolling switch, warning and controls all in one.
- Updated Look: The compact new F90 adopts an updated cowling to keep it consistent with the look of the Yamaha outboard lineup.
- Multi-Point Fuel Injection: With Multi-point Fuel Injection, Fuel is delivered at the optimum volume and time according to ECU sensor signals. This ensures quick starts, efficient fuel consumption, and ample power along with ultra-low emissions.
- Command Link Compatibility: The F90 is compatible with Yamaha's Command Link 6Y8 and 6YC digital gauges, as well as Y-COP®.
- Amp It Up: The F90 features a three-phase alternator that produces up to 35 amps of power — that's 40 percent more output than the previous generation. So there's plenty of electrical power for battery charging and accessories.
- Peace And Quiet: Yamaha's Shift Dampener System (SDS™) greatly reduces the noise commonly associated with shifting gears. Using a new design and components specific to Yamaha "K" size propellers (4.25"), much of the force of shifting is absorbed. The new F90 is compatible with Yamaha's exclusive Talon™ SDS™ propellers, including GP and Pontoon.
- Power Trim And Tilt: The F90C is equipped with a single compact, lightweight PTT unit. The tilt angle can be adjusted with the optional tilt limiter.
