Thanks! I will give them a call to make sure I order the right size or are they pretty standard?For reference, this is what Grady White Customer Service said to use when replacing valve/seacock etc. They emailed me that picture and that matches what is already in the boat.
I know the one on the left is better way to go (or newer way) but the valve in there now was originally installed by Grady and performed well for 17 years on my 330.View attachment 31528View attachment 31528
