Yes - My issue was the screws that hold the sea hood down. I took all the deck hardware off and over-drilled etc. and it was still leaking. I finally decided the only think I did not do was take the sea hood off and fill those holes. Well guess what there is a HUGE void that runs under those screws. I could blow in one hole and air would come out of every hole. I shot a tone of epoxy in the wholes and re-drilled and my penetration finally stopped.
