Like so many old boats, I have one that I just replaced the transom in and part of the stringers. Off course, the foam in the area is water logged. If it is in the back, it likely is in the front too. This is a 21' boat with massive trim tabs on the back (not original). They're big enough for a 35' boat and fill all the transom save for the stern drive. I'm thinking someone was trying to compensate for excessive water weight with these things.
So here's my question: since I cannot remove the deck-floor-liner to get down into the bowels, and know acetone melts foam quickly, what if I tipped the boat up bow high and drill one or more holes on each side strategically placed forward and poured in acetone to melt the foam. In my theory the water mostly settles even within the foam to the low point. So too would the acetone as it flows rearward. It needn't remove all the foam, just all it can while creating a drain path to the rear of the boat where the resultant sludge can be drained away. When satisfied, which includes plenty of days for any remaining water to drain away, I could introduce new foam via those same holes.
To me this sounds viable and yet I've never heard of anyone trying it. So what am I missing?
