Nick - This is most likely not going to help you, however, the Chris-Craft Service manual on propellers shows a 28' Cav. Futura with twin 283's which calls for 14x10 props. The 31' Cav. Futura with twin 283's calls for 14x11 props. The smaller Futuras are shown only with a single engine. I do believe valve springs can fail. When I rebuilt my CC K-95 I found three valve spring broken off at the top. I could not find new springs that were stiff enough so I borrowed some from an old K-95 I had. That engine had five broken springs. These engines were orginally built in 1955-56. Good Luck, Best, Ken J.
Thanks, I'm going to re-check the fuel system and also home in on the valve springs. I don't think any are broken as we'd notice that when adjusting but some may have weakened. Nick
