Help needed with set up

[hurst-weapon]

I have a 17.5 ft bass boat with a xr6 150 on it and I was running a 25p trophy turning 5800 rpm but I took my lwp lower off now im turning the same prop 6300. I was thinking about going to a 25p tempest but from what I understand a three blade will turm more rpm than the four blade should I try finding a 26p tempest or just get the 25 tempest I was looking at and just see what happens since it is a larger diameter prop. Getting 64 mph out of it now with the trophy speed didnt change just rpm would like to get a little more speed since ive got more rpm. Just looking for advice guys. Thanks

If you get the bigger pitch, and you find the engine can't turn it, you could have it cut down. I would go with more pitch. Chuck
