I don't know how many blades it has.  The size came off of Paul's post.  The numbers are very close to the prop for my O-235 (115 hp) Long EZ.  Paul previously said that he borrowed from a Long-EZ owner so he could get higher rpm.
Which is all I know about that prop ... its unsuitability for 13B is strictly my opinion ... Jim S.

5200 rpm on a 62 x 66 prop is not useful for power determination.  If
you look at prop rpm (2390) it tells you that you have about the same
power as an O-235 - about 110 - 115 hp.  
Are those fancy calculations for two blade or three?  I think both of Paul's props are three blade.
