Despite the fact that wood rots, it is a very good boat building material because it has some flex to it. All composite boats can have issues with cracking and tabbing failing due to the lack of flex. If those engine mount pads are cored with plywood what I would have done is to mix up some thickened epoxy (with milled fiberglass fibers or saw dust to thicken it), after drying the hole out and pouring in some thinned epoxy (CPES sealer), use the thickened epoxy to fill up the hole. Then let it cure and re-drill.
The lag bolts SHOULD have been installed with sealer, but you know how production boat builders can't be bothered with such details.
I did some searching and I saw another guy on here fixed it by using a lag bolt that was like 1/2" longer than the factory one. I might do that next year, but the quicksteel seems to have fixed it for now.
