Specially designed for I/O pontoon boats with a performance package and/or other pontoons that prevent the use of other legs due to a lack of space between pontoons or concerns over loss of speed from rear leg drag. The I/O mounting system positions the rear legs behind the pontoons. There’s nothing in the water stream to slow you down or affect performance. I/O Hydraulic legs can be installed on almost any pontoon boat and can be used in combination with two front leg options, the Hewitt hydraulic straight leg or wide base leg.
