I am very pleased with all of the handling characteristics of a stock 24p Bravo/1 4-blade prop on my hull.
The only problem is that I can only spin it to 4900rpm with full trim on my Baja 232 (454 Mag MPI).
THUS the question of LABBING arises ....
Will simply thinning the blades of a prop change the handling characteristic in any way?

Labbing the prop should not change any handling characteristics of your boat. Like you said they pretty much just thin out the blades to free them up in the water and therefore the engine will spin it faster. Usually labbing is good for 200-300rpm. A prop you might want to check out for your boat is a Revolution 4 from Mercury. They don't match up with the numbers on a Bravo prop so you'd probably run a 23p (odd numbered pitch) or maybe even a 21 because they act like a bigger prop. Just a suggestion.

Thanks for the info Tom
I have already tested with a 23p Rev/4 and actually prefer the diameter and rake of the Bravo/1.
My best speed prop is a labbed Mirage/PLUS 25p however it just doesn't work that well for me offshore.
