F70

The F70 is a unique four-cylinder, 16-valve design activated by a single overhead camshaft. The 4-valves per cylinder valvetrain has dramatically increased this outboard’s volumetric efficiency, effectively transferring more air and exhaust at a more efficient rate. This makes the F70 more fuel-efficient, promotes a stronger torque band and makes the F70 lighter than all four-stroke and direct injected two-stroke competitors.
