If you were just worried about the wet foam you could remove the gas tank and cut windows in the side of the stringers to remove the foam. You would have to scab up the sides with some type of retainer when your re-poured the foam back. I think you could get just about all of the old stuff out just from the fuel cavity. This may work since you said your deck is fairly solid and if you don't need to raise the deck I would hate to cut out a good one. I glassed over my thru flour drains and ran them threw the rear wall to the sump and then just pump the sump out. I trailer my boat and it isn't in the water more than 8 hours at the time though. I would want external scuppers drains out the transom if left in the water over night or if I went offshore. I think with the scupper lines crossed I would have problems with water coming in at rest but if you load yours down for work it may need to be raised. The pre 73 4 stringer hulls need to be raised but you can get by on the 2 stringer 74s up if kept light enough. Just a thought. It would save you a lot of work if all you want to do is remove the foam.
