I have a 16' bowrider that has the rear half of the deck rotten, I removed most of what is accesible but underneath the rear splashwell and seats(cap has molded in seats and splashwell) is not easy to get a circlular, jig, or sawzall underneath. The stringers are fully encapsulated and almost a 1/4 thick, so i would like to remove the last half of the foam and install a new deck but the last 18" is almost impossible to get to. I really do not want to remove the cap this year, any help is appreciated.
