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
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.
