I agree with the above. Mine had a 21" pitch, three blade and she could not get out of her own way. I went with 19" four blade and she pulls like a tractor now. If I get another, I might go 19" and three blade to see if I get a few more rpm out of it. WOT is about 4400, top speed about 42mph. I cannot imagine 23" on that boat.
