    how much does my leg weigh

    you can do it yourself. put a piece of 1/4" plywood between the driveway and the skeg. lower the drive, remove the pins, remove the helmet pin and rotate the helmet up, remove the shift cable pin and retention plate, pull the 2 bellows clamps and the hose clamp, then pull the drive up and back.
