Thru hull fittings / Scuppers

[TunaMeltdown]

I had some spare time yesterday and began the removal process of the plastic thru hull deck drains on my 23' SeaCraft yesterday. They are not comming out to easily. I was hoping to remove them in one piece to ask you guys what you recomend replacing them with but thats not going to happen. Anyhow, what have you guys used to replace the plastic thru hulls. I saw the moeller drain tubes but I'm not really sure they are meant for that application? Also looked at the Groco thru hulls and did not see anything that looks like what I am removing? If there is any visible light left when I get home I will take some picture to show you what I'm working with. I had one boat sink because of a failed thru hull and I won't let it happen again.
