Yes, we're using what we have. So far it works just fine. It's a 14" prop with a 13 pitch I believe. We can't go any bigger, and definitely don't want to go smaller. We'll see how it works with regeneration, but from our research, it should work really well.
That's a pretty big prop. Mine is 10 x 8, I think, but I should be able to go larger. I'll look into it some more in the fall.
