Ok I have a 71 Slickcraft SS232. Overall the boat seems to be in pretty sound shape. Drive (original electric shift) is factory fresh, 350 eng. w/300 hrs on the rebuild runs great.Setup with all the goodies for great lake fishing all custom to this boat. The drawback is I'm starting to notice one of the stringers next to the engine is getting soft. mostly at the rear near the transom. When I installed the new livewell plumbing a couple years ago the wood drilled from the transom in that area was pretty clean and almost dry (for a 34 yr. old boat)so with that being the case I don't think my problems go into the transom, but who knows. <br /> First is there a simple way I can detect any water damage in the inner portion of the hull?<br /> Second, The floor feels very strong and shows no sign of rot anywhere. Can there be something going on under the floor that I won't detect until it's too bad to fix cost efectively? <br />I plan to have the stringer fixed this winter. Any suggestions before I have this done to address anything else that could get by undetected?
