I think this is sort of a trick question. The primary design criteria for
a sub propeller is noise reduction, not necessarily efficiency. When I was
in the USCG I was sent to Hamilton Standard propeller school and they said
the most efficient propeller they ever played with was a one bladed model!

airplane prop type?
