Thanks, for the input guys!
The deck does not seem delaminated nor do I notice any difference in sound when I tap on it. I was just surprised hat how much water came out of the hole that I drilled....sounds like I've got some major work ahead of me.
BTW. I did have a survey and it did not show any wet areas in that part of the boat. when he ran his meter over it... don't know that he actually selected that area to do it as it did not, does not look "suspect" however....
it appears that more investigation and much more work is ahead.
