deck repair question

[codfeesh]

fellow ship,in this post i get that you removed the whole upper skin on your deck and replaced all the wood ...then reglassed or used the same skin?here is what im dealing with..i had a soft spot on the side of my motor box so i cut out the piece that was soft and found it was much worse than i had expected.i cut out another piece and some spots were like mud..its a 3/8 inch balsa core...but im thinking of tearing up the whole thing...now i left about 2.5 inches around the sides should i do this the whole deck and tear out all the wood..maybe you could explain your process to me ...i would aprieciate it..

thanks jeff
