Need to add a transom drain plug
 

So I'm going through a full restoration on a 1975 20 CC. I just realized the shop forgot to add a transom drain plug. I need to drill a new one and was wondering if anyone has done this before and has recommendations on how to handle it. size, fitting, location etc.

Drill it at least 1/4" larger then back fill it with thicken resin then re drill it the correct size. This will give you a good sealed hole.

Same idea different twist--I also drilled oversized and used resin to set in a PC of a old fiberglass outrigger tube I had laying around

My Transom is poured do I still need to resin it?

I wouldn't think so. another advantage of a poured transom.

I installed a garboard drain plug assembly thru the bottom of the keel versus out the transom. Therefore, the bilge can be drained while on a lift or a trailer from within the boat without climbing underneath. This also helps maintain the integrity of the transom from water intrusion ;)

I've seen this on Chuck's boat. If you have to drill a hole, this is the way to go. Especially if you forget to put the drain plug in when you launch, you don't have to put it back on the trailer and look stupid even though we all really enjoy that opportunity...

capt chuck were did you get your t handle? then was it just brazed on? I like that set up. my boat is lift kept also and I can not reach the drain plug to drain, this would solve that problem!
