Rubber Drain Plug Options

[peterb]

I have a 1978 23' SF SeaCraft that has a great ride and lines, but old school drain plugs. Yesterday we were several miles offshore and one of my buddy's pointed out that i had a geyser going in the back right hand corner. I figured out that one of the drain plugs on the bottom had come out. I had a spare on board and was able to put it back in.

I have a couple quick questions for the CSC team
1. I am thinking of replacing the rubber drain plug at the bottom of the transom with a brass plate that has a brass plug in the middle. Is this OK?
2. Is my current drain plug setup in both stern corners supposed to work so that if I leave all of the plugs out my deck will always be wet but will drain when I am underway? When i have my boat docked should I leave the plugs in or out?
