too have the issue of the shaft being too long. My bracket looks similar to Scott W's. Does not have the "stand offs" that appear in the picture from Basher. See attached photo. This is in a 23" Ultimate using the 50lb motor. The bolts for the wing nuts barely reach the slots. I can jiggle it and force it to be close enough, just barely, to allow the posts through the slots (slide the bracket up on the motor), but the tolerance is not very forgiving - especially when there is so much slot available. This has to fit better than this...
