Why? Because you get your panties in a bunch when dissagreed with? It's
theory, and I have enough practical pratice (in the real water, not fixing
propellers) to dissagree.

All things being equel, you can drop a pitch when going from aluminum to SS,
because the SS blades are thinner and cut water better.

Perhaps aluminum flex works against fact that in some theoretical
high-horsepower environment - but not in day to day operation with normal
horsepower ranges.

flexes - I think that's generally accepted; but flexes to the point of
loosing
2" of pitch? I find that hard to believe.

On this theory; I'm giong to be way under propped as I had a SS 19 and I
went to
an aluminum 17; so on your theory; this will be like a 15 pitch SS....
