Nate, I did this last fall. Best thing I have ever done for the boat. I used rare earth magnets as you suggest. Taped one inside bilge where I wanted drain and other magnet "pops" into place on outside. I drew a circle around the outside magnet and drilled from the outside. Make sure wherever you locate the drain that it has clearance to install the plug from inside if like mine. I sealed the edge of hole with epoxy before installing the thru hole. I used all bronze Perko. More expensive. Some of the cheaper ones have brass plugs, not bronze, with bronze thru hull. For winter, I hung a length of cotton clothes line with a nail stuck through it in the middle to keep from falling out the hole to wick the last bit of water out of bilge. Worked great. Good luck.

Port leaks and only a partial cover meant significant water/ice in the bilge last winter, which did some damage. Any comments or suggestions? My default is to use rare earth magnets to line up bilge position and outside, drill from inside, install bronze seadog drain with epoxy and screws.
