Ed:

Here are plots from a run on your prop. Here is the color code for the
curves:
Static - red
60 knots - green
130 knots - turquoise
150 knots - blue
160 knots - pink
170 knots - black

You can draw a curve of HP vs. RPM on the HP plot, I drew one on there
for reference but it's arbitrary.
It looks like your pitch is not really 72 inches but more like 68
inches.
