I have a two bladed folding prop on my O32. It's coming off this winter and going to be replaced by a 3 bladed campbell. The problem with our O32s and folding props is that because we are offset to the side and close to the hull the hydrodynamic forces on the prop cause the blades on a folding prop to move, causing lots of vibration. This is true even of the the geared flex-o-fold prop that I have. It's a great prop, it just doesn't work on my boat. I have toyed with a feathering prop, but as I have already dumped $2K into a folding prop that didn't meet my needs, dropping $4K on something that I can't vouch for doesn't seem like a good idea. I believe the campbell for our size is about $500.
