Hello all. I have been reading about some of the things people are doing to small aluminum boats to "trick" them out a bit and I had a question about the floor. The boat is a 1977 Alumacraft F7 std. transom. I want to remove the 3rd. bench seat and put in a low profile deck floor so it's more user friendly to walk through. Any ideas or comments before I grind off the rivets and pull it?
