(If you can't read it, send me a PM with an e-mail address and I can send you a clearer .pdf file of it from original article) That article contains a very detailed description of the hull lay-up/laminate schedule. From that article, I concluded that the stringers were laid up separately and installed about half way through the layup, and I believe they were hollow. The stringers on my boat appear to be hollow, although it makes sense that they would have used wood near the aft end for the engine mounts on the I/O models. If there was any foam in them, I suspect it may have been installed when the rest of the floatation foam was added, just before the inner liner was installed. The 4-stringer set-up was Moesly's original design and continued through 1972. It appears that Potter changed to the 2 box stringers in '73.

Engine was Lag bolted down to the stringers back then. So you will find rotted wood in that area on IOs On OBs the transom is usually rotted. The rest of your stringers should be good to go. Bushwacker sure does have his seacraft history down. I have worked and owned moesely and potter sea crafts and have found them way ahead of the curve back then compared to all other boat construction.
