Suggest a geared 2-blade so that the blades move together whether so that when folded, they both fold.
I changed to a folder 2 years ago and ended up with a Gori racing prop since its resistance to flow when sailing was basically indistinguishable from the resistance of the hull alone. They have other 2 blade folding models that are less expensive. Plus there are several other manufacturers of 2 blade folding props--can't recall their names at present. Recommend talking to Geoff at AB marine for details on prop diameter, etc. since these depend on the room available, the engine and transmission ratios, etc. One of the goals is to increase the diameter as much as practicable so that the blade area of the 2 blade is a maximum given the space available and the pitch is matched to the engine cruising RPM and transmission ratio. Each of these (and probably other parameters I've forgotten) influence the prop size/pitch you need.

(2GM20F - 13 1/2 hp) It's getting to the stage where I should start looking for a folding or feathering prop. What do I need! I've got room for up to about 14". I'm on a mooring, so reverseing is not a big issue. sam :-) 403-617-6280 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
