I replaced the relay controlled panel on my 345 last season. I built a new panel using CarlingSwitch components. They're combo switch/overload protection device models in 5A and 10A sizes. In the process I left a dozen switches somewhere where the SO did not approve of and she hid them from me on my work bench. Long story short... I have a 12 position panel/internal parts from the Robin Radio Marine panel for sale. ALternatively, rather than the goofy relay thing, I would be happy to modify this panel or your panel with CarlingSwitch breakers. You can contact me offline cmanning at metalworkingsystems dot com. Let me know if you have interest.
