I have a 1992 Baja 24 outlaw and I am curious on what a good slip percentage would be? On my 240 sport same hull I ran a 23p mirage, with a bravo 1 at 4800 GPS just touched 65mph. That came up at 7% slip. Seems low to me.

That is a lower than normal slip number. Most hulls similar to yours are dialed in between 10-13%.
Tachs. are notoriously inaccurate and gps reading cam be slightly off which can adjust the number quickly.

Thanks for the info

was playing around with your prop slip calculator, and was a good tool for a starting point on what pitch to start with. I am going to start with a Bravo 1 24p as a buddy has one I can borrow for testing, if that is to small going to try a 25p hydromotive.

Best my 25 ever did was 64.7 at ~5050 = 11.7

What power plant did you have? What prop were you running ? I want to go to a 4 blade but don't want to lose too much top speed, however I hear great things about cruise speed, and handling also handling in the rough, and I am thinking a 25p hydromotive will get me 73ish. Have 502 EFI with right around 530hp as a power plant with a bravo 1 drive. Looking to prop to spin 5200-5400. If I do the calculations with a 10-13% slip that puts me at a 24-25p prop. We will see how it works out I guess

Slip numbers are a great yard stick for checking set up. In my experience, any time you can get to or bellow 10%, you're doing pretty damn good.
I had my old 24' Sonic at 8% and I can't get this one anywhere close even though they're virtually identical rigs.

I'm with BBlades and now doubting my #'s from the first boat.

so if i have 14.2% slip on a 96 22 scarab then something is not right?

No that isn't necessarily true. 10-15 percent is in the unwritten acceptable stage for your boat. However, increasing or decreasing slip numbers can affect mid range cruise numbers and/or top speed. We would need to discuss your application on the phone to get deeply into your options.

I am quite confident you'll be happier with the Bravo 1 versus the Hydromotive.
