F250 SPECIFICATIONS

POWER AND PERFORMANCE

F70

 

Four Stroke 

HORSEPOWER-PER-LITER

An advanced powerhead design features a single overhead camshaft (SOHC), yet with four valves per cylinder, for maximum 
power and effi ciency.  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-liter 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 sacrifi cing 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.
