Hi Y'all, I have a contract on a 2001 C310 and currently awaiting completion of a survey. Changing from a Capri 25 to the C310. I'm doing some research on upgrades and have the following questions. What is the width of the pedestal guard, 12" or 9.5"? I'm looking at getting a folding prop and I understand the shaft is 1". Are all shafts created equal? In other words, if I find a used prop that says it's for a 1" shaft, will it fit the C310 or is there special threads or keying involved?
