With the 5 blade I still get to upper 30's close to 40 and that's the same as all three of my MC's. Someone on here did a Prop test and his results were the same as my findings and his top speeds were the same as my boats too.
I see. I was unaware that the X25 would not do mid 40ish with the stock prop. My X30 runs in the 40s with current stock prop but is kind of a bull on low end with ballast.
Eric suggested the 14.75 X 15.5 LC for better weighted low and with losing top end.
