Yamaha Marine Outboard | 50HP | Four Stroke | Long Shaft | Electric Start

Yamaha F 50 HETL - Series MIDRANGE
For those who rely on their quality time.

Nothing beats a day on the water with family and friends. And nothing powers those moments quite like Yamaha’s versatile line of midrange outboards. Ranging in size from the mighty F90 down to the nimble F25, they offer just the right amount of power for a variety of applications. These 2-, 3- and 4-cylinder dynamos are quiet, clean-burning, reliable performers. But that’s not all they have to offer.

 
Here’s what makes each member of the Yamaha (F 50 HETL) Midrange family unique:

 
Fuel Economy.
Precision Multi-Point Fuel Injection (except F25) uses individual fuel injectors and a system of on-engine sensors to deliver an optimal fuel/air mixture to each cylinder. F25 models use our PrimeStart™ auto-enrichment system. Both provide easy turnkey starting, smooth acceleration and maximum fuel economy.
 
Optimum Overall Performance.
Microcomputer Ignition, featured in all Yamaha midranges, adjusts timing to maintain optimal engine performance, economy and power under all operating conditions.
 
Smart Design.
A Single Overhead Camshaft (SOHC), on the F25 through the F70, provides a compact, lightweight, space-saving design that won an Innovation Award from Motor Boating and Sailing magazine.
 
Ergonomic Control.
Yamaha’s award-winning, Multi-Function Tiller Handle is available on all F30~F90 midrange models. These handles feature Variable Trolling Speed (VTS™), allowing you to fine-tune your trolling speed in 50-RPM increments with the touch of a button.
 
Easy Engine Flushing.
A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and long engine life.
 
Anti-Corrosive Barrier.
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 Yamaha portable four-stroke engines.
