Nate, I installed a drain last year. I used magnets too and drilled from outside. I also used a door drill kit and a drummel tool and installed the drain flush with the hull and faired it with epoxy. If you need pics or more information pm me. You can buy flush nylon plugs by sea dog? and don’t need to use the big awkward bronze plugs unless you want to. It’s peace of mind being on the hard for 6 months. My boat has never been dryer over the winter. Len Mitchell Crazy Legs 89 37+ Midland On.
