If you've done some core samples and are certain the foam is dry thru and thru you can leave it. Unless it will be in the way of your work, then you would need to remove it and replace when done. What type boat you working on anyway?
do core samples in different places of the foam.........then do samples on the stringers....if the stringers are dry....and the transom is good....button it up and go fishing .......

Center stinger is the only rotten one. And thats only for 2" in the center where someone screwed something down. The deck had 4" rotted holes all over it, again from someone screwing stuff down.
