    Looking for a ballpark of what guys are using for props on these boats. Have a Cummins 6bt 250hp in it, 2.5:1 transmission. Thanks

    Do you know what diameter prop can fit, how big is the aperture?

    There’s more room than I can swing. I believe I could fit up to a 26”

    26x24 4 blade may be around where you want to be if you have a 1-3/4 shaft. From what I've picked up, you want a four blade, largest diameter you can swing, low shaft speed and of course be able to reach your WOT. Do you have any data (speed,rpm,wot,etc) on what you have now?

    I've got a novi hull with a 250hp(cpl953),2.57:1 and I have a 23x26 high cup. I'd like to pitch down...

    I don’t have much data. Ran soft all year last year as the tach wasn’t working great. I just bought a 25x24. Hopefully that’s the ticket.
