Greetings. Just inherited a 1981 J24 and sorting it out. The Keel sump looks like it was chiseled out in this area for some reason and now the backing plate is not supported. In addition, it is taking on a very little amount of water (I sponged it out a week ago and this is whats in there now). I don't think there is any other leakage going on that would have gotten in there (dry weather). I am assuming I need to fill this with epoxy?
