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

A Composite Intake Manifold features 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.

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.

Reliability & Durability

Corrosion Protection

Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all the Yamaha Midrange 70-, 60- and 50-horsepower four strokes.

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.
