This boat I just bought is a cherry! Except,, a few soft spots in the floor in the back under the gas and battery. The transom is solid as a rock and so is everything else. These are just a few very small spots that crackle when I push on them. My question is: Im definetely not re doing the deck! So, with that said is there a patch work I could do or maybe plywood over? I need the cheapest route that will still render years of use.. Thanks a million!
