73 Tsunami scupper question?

[Entourage]

What are you guys doing about the old brass scuppers? I think they may be leaking a little. I had some old through hull transducers that i just removed that may have been leaking on me. I have not tried the boat since i have filled the holes so that may have solved the problem. But if i still am getting water in the bilge i am going to the scuppers. Any suggestions would be appreciated.
