New prop? Yes or no

Hello,
I have a 2001 Tracker, Nitro nx750, with a Tracker 2 stroke 90hp. It has a 19 pitch 3 blade propeller. A 4" setback manual jack plate.

Would changing the prop make any difference, is it worth doing.

Thanks

There is people with far more knowledge than me but my best reply is what are you trying to accomplish?

Have you fine tune your set up and confirmed your current prop is in tune. Is your motor in tune and working at its full potential. Is your prop to pad at the optimum height. Is your weight distribution correct. Props are a easy thing to change and often the first thing people want to change but before doing so in my opinion there's multiple things to check first.

Try different engine heights and note water pressure and rpms. Full throttle should have you at or close to rpm red line.
