i added a wedge to my old malibu, they wouldn't supply me with a wedge mounting plate, (had to make my own out of stainless). i know that the malibu transom is 3/4" solid fibreglass to take the forces the wedge applies to it. i also glassed in a 1/4" stainless steel plate to the inside of the transom to spread the load. i wouldnt try fitting a wedge to another boat without some serious hull modifications
