I like to be in the upper end of my RPM range (but NOT over it).

Most guys, when going from an aluminum prop to stainless tend to pitch down (going from 17 to 15) to make up for the weight of the prop.

My bet would be you "might" get a different outcome with a 16 pitch prop. That said, I think the difference would be negligable.

I do know that certain companies have "prop days". they bring several props to the water and allow you to test them on your boat out on the water. It is a great way to find that exact perfect setup for your boat.

In your situation, I would stick with the 17 pitch. I just don't like going over the recommended RPM range. Plus, I prefer stainless
