I thought Skippy had a "21' Bilgeliner?

Just sort of lurking in this conversation, but if a stainless prop and

Stainless steel is STIFFER than the aluminum prop and will outperform
it. Also, aluminum props ding up much easier than steel props. Stainless
is the way to go.

Identically dimensioned aluminum and stainless props will perform about
the same under identical circumstances for most boaters. If you are
pushing a 21' fishboat with a 200 hp outboard, and you have two props, one
alum and the other stainless, and they have the same pitch, diameter and
blade geometry, the performance will be about the same. Different cup
design, very high speed boat, et cetera, and thinner blades available on a
stainless prop might make a difference.

What would an ersatz Skipper know when the real Skipper never owned a
boat?
