STEP UP
TO BIGFOOT
Big-time power. With a longer design and
bigger components, Mercury BigFoot was made
specifically to
deliver the type of power, thrust
and control that wider, heavier boats demand.
Taller gearcase puts the prop deeper, below
turbulent water, for improved performance.
Unlike the three-blade prop found on other
outboards, our low-pitch, four-blade prop
increases control especially at lower speeds.
A low 2.42:1 gear ratio delivers thrust
and maneuverability that big loads demand.
