Yamaha proudly announces a new addition to its mid-range four stroke stable; the F70. Using advanced features and 
technology to make it extremely light yet very powerful, it is the ideal outboard for a myriad of lightweight fi shing, 
family, and pontoon boats.

Featuring the lightest weight and highest horsepower-per-liter-of-displacement in the 70hp class, the Yamaha F70 
takes advantage of the leading edge of technology while maintaining the fuel-effi cient, smooth, and quiet operation 
Yamaha four strokes are known for.  And it has benefi ts like Yamaha’s available Multifunction Tiller Handle or our 
Command Link® System, which let you harness its Variable Trolling RPM capability.
