Re: Thru bolt hull to top - advice wanted
able1111, if the hull and cap are still bonded I would leave it alone. Lifecaulk is fine, we used it at the boatyard for years. The only thing I would rec. is to drill and tap the fiberglass, then flat washer and nylock nuts. You can get a 3 piece tap set from morse and use the starter tap then the main tap. You won't need the bottom tap but I don't think they make a 2 tap set. Just put a little caulk on the threads and under the head and it will be plenty strong. If you're worried about it go from a #10 to #12 flat head ss screw. Remember the joint has to be tight before you tap. You can use a slow speed drill on the tapping. Afine thread fastener will work better imho
