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!
