Well, I just had to. Bought a surplus FC470 Zodiac. It's missing the floor--expected that. The transom and bow thrust board look good and the control valves are there and turn. The overpressure valves are gone and it looks like the CO2 valves have been canabalized--look open to me. There's a valve base in the bow...that's missing and I'm not sure where the inflation valves should be. There are two valves just above the C02 valves in or near the stern. Parts books show them as the place for the over pressure valves. So, I need some advice and parts. Can send pictures if someone is out there willing to look.
