Prop calculator comes up with 39% slip using the figures you posted.
4700 at 30 kts is more inline with performance from a 17" prop

Are you probably under pitched and hitting the limiter there, I’d say.

Prop selection is more of trial and error than it is science on paper. Buy used props in good condition and resell them if they don't do what you want and buy another. I have probably bought 10 props for my current motor setup and some I like and some I don't. I'm always looking for that silver bullet that will give me the best holeshot and best top end. There's no perfect combination. I sure would like to try a 14.6 X 15 Revolution 4 but can't find one at a reasonable price so I'll just wait.

What does your issue have to do with the OP's thread?

the 6 questions in the sticky at the top of the forum take the trial and error out of the prop selection. Additionaly with a single gear, you can never get the best holeshot and the best top end with a single prop.
