What prop were you running?

I'm a fan of the 253, get some seat time in it and some kplanes - they are a decently fast hull

Hydromotive 23 Q4 prop works best on my 253 with stock 502 415hp. Boat just wanted to launch with a bravo one four blade when you hit a wave, when you are running hard trimmed and no tabs down that is. My hydromotive is faster, safer, and does everything better than all the props I tried. I tried mirage plus, bravo ones, hydromotives and all different pitches in those. I run 67 gps top end, cruising you always have to run your tabs in this hull. 465hp and the right hydromotive prop labbed should get you to 70 IMO. I can squeek by my uncles 25 outlaw with the same engine as me, he runs a labbed 23 mirage plus.You made the right choice just spend time dialing it in.

Thanks appreciate the input,but would I need more prop since I am running a little more HP?

Convincedher

Yes you would. The hydromotives come 15.5" diameter and mine has been cut down to 15" and doesnt have a diffuser ring, I turn that 5000. So I would try to find a 24 hydromotive and see where your rpms are at, if they are low, hydromotive or bblades can cut the diameter and lab it for more rpms.

I have many friends with 253's and all of them have 502 mpi's (415 hp)...all of them run 68-69mph with 24 pitch bravos right at rev limiter... one friend did headers and is now 71 mph...and after testing props, he is using a 26 hydromotive
hope this helps
