21 super boat prop question

[wickedwitthestix]

Ok here’s the deal fellas I’ve tried a few props the best overall so far has been a 24 trophy plus about14-16 inch set back and a inch below pad best it’s a 225 promax and spinn ing around 6300. They say the sweet spot is 6500-6750 should I go try a 23 trophy or any other ideas to bring the revs up it says the rpm band is 6250-6750 so I’m on the bottom end. Rather b on top end. Also has a bobs knows cone. Thanks for your responses in advance
