I have a 1990 (#1093) C34 Mark 1.5 with a M35 30 hp. I have been looking at several different folding props and really like the Flex-O-Fold 2 blade. Just got a letter back from the factory and they suggested a 16x13R propeller. Now I have a 15x10 Michigan Wheel 3 blade fixed and I believe I am over propped as I can only get 2200 rpm on the newly calibrated tach at 7 knots perfect conditions. What size shaft did my boat come with and what is the forward ratio of the Hurth 100.
