What props do you run on your 29 outlaw
 
I have the 454 carb motors.

I've got 24 pitch bravo 1's (4 blades)

what speed are you seeing?

I had a 2000 29 outlaw twin twin 454 310s had a set of stock 4 blade 24s that ran 64 to 65 on gps and a set of labed 25 three blades that ran 67 on gps on a good day

My 2000 with 310 MPI's came stock with the 25's but I hated them on Lake Erie, and some days could not even get the boat on-plane in big swells. Loved the 24 B1's and their even better if (labbed) because of the deeper "X" dim.

Lost 1-2 mph, but it was worth it to me.

I did try some Hydromotive 4 blades, but the B1's hold better.

+1 agree 100%

Labbed Bravo 28's on a 1.34 gear. My motors say 454 MPI Mag on them. That means they are 385hp a side, right?
I see mid 90's on a good day. Low 90's when it gets hot or I'm heavy on fuel.

Did you know the prop size often stayed the same even when you went up on HP on many of the Baja's.

Meaning a 7.4 - 300 or 310 HP turned (say) a set of 24's at the engine rating of 4400 to 4600 RPM.

A 454 Mag - 350, 375, or some 385 HP turned the same prop size at their recommended RPM range around 4800 to 5000.

And the 502's and 496 HO's used yet the same prop size to run 5000 RPM or a little more?

This doesn't make sense too me? Educate please? I've got a 99 29 OL w/mag 385hp & 24p Bravo 1's. I get 66-67 gps 4700-4800 rpm's trimmed up.

What he is saying is 99% of the boats (29's) that went out of the Bucyrus doors has the same propeller on them regardless of the engine package.
The RPM ranges of the 454, 496 & 502's were/are different depending on HP.
The 454 came in 2 hp levels when it became fuel injected. 310(330 later?) & 385hp.
The upper RPM limit of the lower HP 454 was only 4800 +/- 50 rpm & the 385 motor was 5200 +/- 50 rpm.
Now you have 2 identical boats with different engine packages, both equipped with the same propellers (24p B1's). The one with the lower HP motor may be just slightly over propped, meaning the motor doesn't have quite enough poop to get to it's maximum RPM & or have a boat that is under propped meaning the RPM will spin faster than it's maximum rating.
There is an inverse of that example, which I think is what is confusing you.
Your boat is over propped, which is good for you. This leads us to lab finishing.
By lab finishing your propellers you can gain RPM. The lab finish process tailors propellers to match your boat's characteristics.
Much like an off the rack suit, it may fit well but there are areas that need taken in or out to accommodate your build. That is where a tailor (lab finisher) comes in.

Make sense now?
