after pulling apart my boat ive learned allot about inspecting boats, and determining the condition of fiberglass cored materials. im one of the unfortunate ones to have a rotted transom, and can give you this info as far as examining it. you will not be able too tell the condition of the core from the outside skin (unless it sounds very hollow upon tapping), it is too thick. get acess to the inside skin and push it hard!, if it gives, you have rot, if not you should be okey. chances are there will be some trouble around the outdrives, however theres not as much torque on the tranny so its not that much of a problem, good luck!
