I found wet hull sides below the molded intake vents, in the area of the through hull there where the intake vents and all of the drains from above are plumbed to and drain overboard.  The backside of this through hull seems to be completely inaccessible as is.  Has anybody replaced these?  I am thinking I may have to cut in a 4" hole to stick my arm through and then add an access plate to the hole when I am done.  If any one has done this already or has any advice, it would be greatly appreciated.
