Let me correct me by saying I had both the floor valve and pressure relief valve done at the same time, upgrading to a C-7 vale and the new style pressure relief valve.
Hope you can get it apart without hurting it. I believe I saw new ones like you have in your boat at AAA a couple of years ago. My problem with my two boats......one a friend borrowed for a Grand trip and cross threaded it while trying to clean it.
The other one was badly corroded and I destroyed the threads trying to get it apart.
