I don't know that there's enough plastic to grab with slip joint pliers like you suggest. From the photos I saw of these, they look a LOT like Halkey Roberts valves.

For 12 bucks I'd order a metal internal wrench that's way stronger than plastic and give that a go

Ordered the Halkey Roberts valve wrench, but will definitely soak with hot water first. Just don't like the idea of lubricants on the rubber if I can avoid it. Thank you all for the suggestions.

So, it's been 5 days since the last post. Did you get your valve out? Inquiring minds and all that nonsense

It is a slow leak at the tube tip that has not taken kindly to patching, so I think I am going to limp through the next few trips and then do a full replacement with a C-7 valve and urethane tube from an Outfitter II. Measurements seem to be close enough on the two boats, but I do not want to destroy the old valve and be forced into a major repair during the season. I Will let everyone know if the swap works as I wanted to upgrade to urethane over the vinyl tubes that just seem to get pinhole leaks all too often on western rivers.
