Using advanced features and technology to make it extremely light yet very powerful, the F70 is the ideal outboard for a myriad of lightweight boats.
- Horsepower-per-litre: An advanced powerhead design features a single overhead camshaft (SOHC), yet with four valves per cylinder, for maximum power and efficiency. Total intake valve area is increased 17%, while the pistons and valves are up to 10% lighter (when compared to our T60 model), giving it substantially more horsepower-per-litre of engine displacement than competitive outboards, both four stroke and two stroke direct-injected.
- Lightest weight in class: From the specially designed engine block to the two-piece upper case, every ounce of weight savings has been realized for maximum performance without sacrificing durability. Yamaha’s new F70 is not only the lightest four stroke 70 horsepower outboard, it’s even lighter than competitive two stroke direct-injected outboards.
- Precise throttle control: All air entering the engine block of Yamaha’s new F70 four stroke 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.
