Re: [Electric Boats] General direction in propeller efficiency

 

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.
