Light and powerful, they sport 1-liter displacement, single-overhead-camshaft designs and electronic fuel injection. They deliver quick starts, high performance and incredible efficiency for aluminum fishing boats, pontoons and fiberglass boats. They also offer incredible trolling flexibility with Yamaha’s exclusive Variable Trolling RPM Switch. Available on the F70, F60 and F50, this allows anglers to adjust trolling speeds in 50-RPM increments. The Yamaha Midrange 70-, 60- and 50-hp four strokes. Solid choices for any boater.
Owner's Manuals
IMPRESSIVE TORQUE & ACCELERATION
The impressive F70 Midrange weighs in at up to 80 pounds lighter than its competitors, giving it class-leading power-to-weight. Its siblings, the F60 and F50, also boast the same, ingenious engineering, with fewer horses.
POWER & PERFORMANCE
Single Overhead Camshaft
A Single Overhead Camshaft (SOHC) on the F70, F60 and F50 provides a compact, lightweight, space-saving design.
Fuel Economy
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.
Precise Throttle Control
All air entering the engine block is routed through a single throttle valve, to ensure the precise amount of air necessary for optimum power and fuel efficiency. It then enters each cylinder through individual long intake tracks, which are 'pulse tuned' to provide air at the precise volume and timing for maximum density and power.

Convenience & Control
Control and Comfort
Our optional, award-winning Multi-Function Tiller handle features a Variable Trolling RPM Switch (VTS®). It allows for precision trolling speed adjustments in 50-RPM increments. Compatible with all Midrange models.Easy Engine Flushing
A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
Gauge Compatibility
Optional Command Link® gauges provide real-time outboard performance, boat systems and environmental data at your fingertips. Streamlined displays are designed to withstand the elements and are available in square or round style for single- or multi-engine applications.Product Videos
