Yamaha Outboards MID RANGE
Looking for a midrange? These pulse-tuned, 3-cylinder, 40hp - 90hp dynamos are the most powerful in their class.

They're packed with features usually found only on larger engines, and you can have your choice of either Remote Control Steering or our Multifunction Tiller Handle for fingertip control of starting, trim/tilt, shifting and throttle.

On all Midrange models, Precision Blend™ Oil Injection provides cleaner, smoother trolling. Loop Charging and Pulse Tuning maximize performance.
