need thru-hull at bottom of locker on 204 Fisherman

[gradyrod]

I am replacing the side thru-hulls (plastic) on my 1985 Fisherman 204. While removing the hose I cracked the bottom of the thru-hull that allows the aft storage area to drain. Does anyone know the diameter or type of thru hull that sits in the bottom of the locker that I now need to replace?
The hose running from the bottom of the locker drain to the side thru hull is 1 inch in diameter.

Thanks for any info here!
