    I am thinking the Z8 I ran had a 225 w/Tempest 24. Ran into the low 60s and overall pretty good performance from that prop. A 25 fury might be a little steep for that rig based on your RPMs.

    I fished out of that boat a couple times and I remember it getting out of the hole pretty good. It would also shoot one of the biggest rooster tails I've ever seen.

    Haha, I honestly don't remember it throwing that big of a rooster tail but that is more a function of engine height and trim and little to do with prop as I understand it. I could be wrong, I am not a doctor. I have always heard a rig is set up right when the tail is about the same height as the cowling.

    Anyway, lift was fine.

    The more I think about it I would experiment with raising your motor up a 1/2 inch or so and seeing if that gets your RPMs up. Also, there is a Nitro board on Bass Boat Central where you can find what numbers folks are running, height above pad, etc.

    What did you do with the 26" Tempest? Did Steve just take a 27 and turn it into a 26?

    That sounds about right. You went from 58 to 64...very solid improvement. However, when it warms back up that ProXS will run between those two numbers, just fair warning.
