My boat has a drain plug below the motor. Kinda awkward to get at and am wondering how hard it would be to add one on the transom? Thinking a threaded tube and brass plug at the bottom of the stern. Is this asking for trouble? I'm used to pulling the plug when I load up and then putting it back in once before launching. Just a habit I had with my old boat and this boat will not be stored under cover for a bit so it will collect rainwater.
