Guys, We did this installation last year just like the pictures here show.... however, we used a bolt to anchor one of the holes in the inside flange and bonded the mast, etc. to it for safety reasons.
Years of tinkering with an auto bilge pump with separate battery and then failing that, a once a week visit to use the car battery and long wires to run the pump for a few seconds just got tired..... d this and forget it, don't forget to take the plug out though.

In all the pictures you have seen the hole is drilled in the keel stub above the lead portion of the keel. Garbord drains are common practice at the boat yard where we launch our boats. Most are the Perko ones you have shown in the Dan.Pfeiffer link. The purpose in our boatyard is to prevent water buildup in the bilge but there will still be some water there up to the leve of the bottom of the drain hole. I used stainless screws but perhaps should have used bronze. Also set in Epoxy in one case and in 3M 5200 in the otehr and faired over using thickened epoxy. Some owners do not fair around the flange. It is basically no different than a thru hull.

So would you drill vertically down in the bildge, then horizontally from outside so the two holes meet, then oversize the outside to accommodate the plug housing? Drain plug housing I am looking at has four retaining bolt holes. Seems not a good idea to put self tapping screws there, so that means you need to through-bolt. And if that's so, how do you put washers and nuts on the inside? Even if I didn't drill vertically down it seems that you can't encompass lowest point in the bildge, have horizontal drain plug and through-bolt all four retaining bolts. So What gives? These pics are pretty good, but it looks like he just put self tapping bronze screws. http://dan.pfeiffer.net/10m/garboard_drain.htm From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Joel Aronson Sent: Wednesday, October 23, 2013 2:28 PM To: cnc-list@cnc-list.com Subject: Re: Stus-List Installing a garboard drain plug on 38MkII mine with as installed from the outside. Not smooth, but not a big deal. Much lower than if it were installed from inside.

Shallow bildge and external lead keel make it pretty difficult to have something that is flush on the outside yet encompass the lowest point in the bildge to allow water to drain.
