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.

Also, I am now getting 5600 rpm, which would yield 2580 prop rpm's, not 2390.   Paul
