What does a smaller pitch do to top end?

It may not move at all!!! Higher RPMs, but less pitch.......some times its a wash........sometimes not. I went from a small diameter 19 to a large diameter 17.....better hole shot and faster top end!!! My RPMs went from 4900 to 5400........go figure???? Hats the difference between a cheap SS prop and a high dollar

it depends,
if you can't twist the big prop then you are not getting max MPH any way.

so in this case you may actually see better performance.
google "prop speed calculator"

assume a 10% "slip" and take a look at what you have.

I have given up on top speed, but I've been blessed to own a few Allison's back in the day so it's out my system.

when fishing, set that bad boy to rocket out the swamp with a load and fish on!!!!
