Jerry,
I think the best advice I heard on seacocks if make sure you exercise them several times a year to keep them from freezing up.  Here is an article from Boat US which may be of interest.

I expect West Marine would have a suitable replacement.

Is it just the valve or is yours part of the through hull?  - rob

Subject: [Rhodes22-list] Through hull replacement?

Hi all,

The through hull for my marine head appears stuck (frozen) open, but was not
letting in any seawater last year.  It is on my maintenance list to address
this spring.

Anyone had any luck sourcing parts/replacements? Any tips and tricks? I
would hate to end up with a hole in my boat!

Thanks,
Jerry
