The pressure created by the prop pushing the boat is orders of magnitude
greater than anything you could attribute to spinning the weight of the
prop. The different between aluminum and ss would not be noticable.

I purchased 2 props (both alumininum) to reprop with.
The guy agreed with me that if I hit stuff; it's better to destroy the
prop than
the outsdrive -- but for performance, a ss is the way to go.

he said the weight issue is silly because it's underwater and doesn't
weigh as
much and that no one would use ss if it wore out the outdrive faster.

So -- Here I am; for curiosity sake; asking you if the weight of a ss prop
really does wear out the drive faster than an aluminum one.
