surprise! wet foam in stringers

[jesusv]

as i was removing the glass on the transom to remove the coring i cut back the stringers, as i mad my first cut midway up the stringer water begins rolling out. i made another inspection cut about 1.5 feet from the transom and same thing. what now? its a 23 inboard and im in south florida dont know if i should be putting this much time into an inboard, which is a great boat but realistically an outboard would be much better for so. fl.. thinking my time would be better spent on an outboard model. any suggestions, advice?
