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.

Subject: Stus-List garboard drain install for a 30-1


I plan to install a garboard drain in my 1980 30-1 for this winter. 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. 
Thanks
