+1. Replaced a two-blade fixed on my 30-1, A4, 7/8” shaft, with a two-blade Gori folding prop, before the 2017 season. I’ve been running the Gori for two seasons now with absolutely no problems. I think it gained me a half-knot easy.
Here are the specs on my shaft and prop from Geoff Prior of AB Marine (US distributor for Gori): * RH rotation, 7/8” dia SAE shaft taper which has a ¼” nominal key & a 5/8” x 11 UNC thread. * So for your C&C 30 with the Atomic 4, rated at 30hp, 3000rpm, (20hp @ 2000rpm) with the 1:1 gear ratio, RH rotation, 7/8” dia. shaft it’s the 11.5" x 8 x 2-blade RH. I bought the Gori on sale for $845, which was $50 more than a Martec and $185 less than a Flex-o-Fold.
