I had always heard "leave 15% tip clearance."
Perhaps they used 15% of diameter instead of radius. If so, 2" would be appropriate clearance for a 13.3" diameter prop. Whereas it would actually be enough clearance for a 26" prop.
Kev, where did you come up with 2" of clearance from the hull, just wondering.
If you size a wheel to that becomes a pretty small wheel.The rule of thumb has been 1" if memory serves me well.My Sabre 28 turned a 14" wheel which gave me 1" clearance. Some of the folding prop vendors claim it can be within 1/2" clearance.Personally I'd want to run the largest wheel I could get away with going the EP route.Bob
