I have a 07 x-15 with a 14.5x14.25 prop- maxed out rpm is 5100- is this correct? Mcx motor- I had a prostar before this and rpms were much lower. prostar was a direct drive with a 13x13 prop. Thanks for any help

X15 is a 1.56:1

Your old boat was a 1:1

Why you goin that fast anyway? Footin?

Yes, that's the correct rpms.
If you want more topend speed and lower rpms at other given speeds, go to a higher pitch prop. If you load the boat down heavy or boat at altitude (or just like the punch out of the hole) then leave it as is.

Thrall, thanks- this boat was at altitude and I love the way it punches- would the gas mileage be any better with a higher pitch prop?
