Just sort of lurking in this conversation, but if a stainless prop and an
aluminum one were exactly the same dimensionally, why would one perform
differently than the other? Friction differences due to surface
characteristics?

Doug, no one would make a NiBrAl, brass, or SS prop with blades as thick
as needed for the "same prop"(dia, pitch, area, shape) in aluminum, so you
will never be able to make that comparison.

A SS prop will be forgiving on logs & sandbars. Personal experience on
our Glastron shows little difference in speed(SS slight advantage) but the
SS is less prone to blow-outs and gives a better trim attide than the
"same spec" aluminum.

Polished SS props can be very pretty on your floating Camaro, too!

With that last line, you sold me on aluminum, simply for spiritual reasons.
Too many floating Camaros around here, driven by "brunos", as my son
(correctly) calls them. If I ever find out I have three months to live and
prison doesn't matter, I plan on adding some new fishing structure to a few
of the lakes around here. :-)
