alafa stern drive no reverse acts as if it could be out a notch on spline in lower half.do you have to remove lower to turn the shaft a notch on the spline.or how far would you have to drop lower to rotate the shaft
Could be a lot of things, what have you tried repairing?
about 3/4 of an inch.thats assuming it was reassembled correctly and not just drawn together by the nuts.
