Anyone have numbers for cracking pressure for new Shrimp BOVs?
I recently bought a used one and couldn't adjust it to crack until over 4" H2O. I haven't had it in the water yet, but it was terrible at the surface.
I took it apart, cleaned/lubed the o-rings and put in a new LP seat and was able to adjust it down to about 3" without freeflowing (adjuster set all the way out). I usually get my Apeks 2nds down around 1.0" doing the same.
The valve seat looks good. The shuttle valve 'arms' have a little wear, but look ok. Same for the lever.
Any suggestions or is this as good as they get?
