I have a deckliner 224. It has 3 drain plugs as it is a trihull. One the outter hulls the drain plug is about 6 inches from the bottom of the boat. When I was putting a fish finder on the boat, I decided to put it on the bottom of the left hull. After I drilled, it started draining water. I had always assumed that portion of the hull was sealed. I am sure I do not need to leave the water in there. Any ideas?
