1998 Ventura deck boat. There is a cooler (I think?) in the floor. It has a drain in the bottom, the drain just drains into the bottom of the boat. When I peek down the drain, there is always water in there. Shouldn't it drain to the back of the boat? I am in the process of replacing the rotten transom, so the boat is sitting on the trailer, have the bow of the boat raised well above the stern, but the water isn't draining. I tried poking a wire from the back, under the ribs, and I can't find any spot in the rib where the water could drain. How is the water from the cooler thing supposed to get out?
