I have a 1987 14'4" wahoo that i bought last year. This week i was washing it out in my driveway with all the drain plugs out, and all the water that drained out, came out of the center drain plug at the lowest point of the transom which would be under water if the boat was in the water. I read that these boats have two hulls with a space between them. Question is, is water suppose to be in there, or is a bilge pump go down there, I can't find an opening for one. I do have a bilge pump on the top hull under the floor. Thanks for any help
