Buy New Yamaha F70 70HP 4 Stroke Long Shaft Outboard Engine
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.
