[3rdday]

Terry,
I put a fishbox/ in my floor probably close to the same location as your livewell.I have mine draining into the bilge. I too faced the same challenge. I wanted to drain out the transom, but #1 I have a backing plate for the outboard bracket in the low corner of the fishbox. I also did not want the chance for the plug to be "forgotten" or pop out! I know the wise confuciuos say; "man who drain fishbox in bilge have stinky boat" .
