Help Identifying and Replacing this Cockpit Drain:

[Beersmith]

The pictures below are one of two of my original cockpit drains. They appear to me to be something like a bathtub drain, but I cannot find a similar sized replacement anywhere. Maybe I'm just not looking in the right places though. Can anyone tell me what kind of drain this is or point me in a direction to find a replacement?

The flange diameter is exactly 3", the threaded part is 1-3/4".

Are you trying to find an exact replacement? Have they failed in some way?

Just trying to get a feel for what you might be in the market for. Try the usual catalogs and I think you'll come up with some good replacements. You might try local second hand marine stores too.

kind regards,
