understood,
this new hole is a "pass thru" to drain the upper shelf were my fresh water tank sits. Prior to my new drain hole, the tank was sitting in a 6" deep puddle of water from the life of the boat. so, much so, that all the gell coat is flaking off of that whole area. I guess the freezing and thawing has been popping it off for years.
My new drain hole, did drill thru the fiber glass then marine plywood, but this top shelf is seldom wett, only from water run off or spillage of one kind or another.
So, the new drain hold will actually keep my engine bilge drier, and allow the excess water to end up in the boat of the boat, and then get pumped out.
