Just looking for some help from someone smarter than me. I have a 14' Kenner Craft fiberglass boat with a 25 HP OB and I cut out my rotten transom from the outside. Big mistake after I started reading around. Anyway with damage done what is the best material to use after installing the plywood? I noticed after doing research that there are numerous products out there and can't narrow down the list. Finishing the boat doesn't concern me it is getting the strength back for the hull that does. e.g. best product to use tying back in to original laminate,etc. etc. Thanks.
