Been there, done that, still leaks.
I had the same leak which I fixed 90% by rebedding the screws for the sea hood. I redrilled and even had to chisel out the destroyed glass around two of the old holes and enlarged all holes and refilled them all up with epoxy. In a couple places this was hard to do because there is nothing but air space underneath, where prior damage was deep. There are some ways to get them partly filled with a false bottom long enough to get a plug of fast curing epoxy or marinetex in there. Then I filled the hole "past full", so that after drying I could sand it down to fair. Once the old hole was filled and fully cured, sanded fair, I carefully placed the seahood and redrilled the right sized hole.While I had the sea hood open, by the way, I cut two 6" rounds of fine mesh (no-see-um) screen, placed them over the 4" dorade vent pipe that lead down into the cabin, strapped them down with nylons ties running horizontally around the outside rim of the pipe and then "pinned" each tie in place with a pair of "dots" of Gorilla Glue, just to keep them from slipping up or down.I still get water coming in once in a while, Joe, but only when I'm gone from the boat. But 90% of the problem is gone, so I figure I must have done the project 90% right.Eric
