Assuming 10% prop slip, that's what I calculate also.

51 mph at 15 % , and 48 mph at 20%.

Would a SS prop reduce slip?

=================================

It's hard to say, but it might. The advantages of stainless over
aluminum are structural rigidity (less flex) and surface smoothness
(less friction). Improving either quality could decrease slip which
would have the effect of increasing speed at comparable RPMs.

I wonder if powder coating a aluminum prop would improve the way an
aluminum prop works?

Doubtful, in my opinion. The powder coating will add nothing to the
rigidity of the prob and is not a smooth, polished finish.

Aluminum can be hard coat anodized, polished and the surface can approach a
Rockwell hardness that is close to stainless, however the coating is only a
few microns thick at best and will basically be a non-event in terms of
making the bulk of the aluminum blades any stiffer.

That's the answer! A Prob instead of a Prop!

But very cool information.
