All 4 of my cockpit drains T together and go to the seacock under the galley sink. (Thanks PO) I need to fix this it looks like the two furthest aft though hulls are where the the center ones are supposed to be connected to after crossing over. At least that's what I understood from the Cockpit" drains to bottom" post. They currently have seacocks and caps on them. I assume the seacocks are unnecessary as they are above the waterline?
