WHATS THE DIFFRENCE IN RMP FROM A 26P & 28p?? BRAVO 1 PROPS?? ALSO WHATS THE DIFFRENCE IF BOTH PROPS WERE LABBED?? THANX

300-400rpm

Yes sir.

(tiny stern lift not really worth mentioning)

How much mph will you gain going from a 26p to a 28p? I spin the 26p at 5400rmp I would like to stay at 5000. What would a five blade do for me? I have a 25' warlock cat with 670hp n/a motor. I don't know what my gear ratio is. Do you lab props and sell them also? What would I pay for a bravo 1 28p prop labbed? What about a five blade? some one told me it would work better on my boat then a 4 blade? I want to try to get the right prop with out buying 2 or 3 of them. I'm a poor boater! LOL Thanx for all your help!! This is the best site I found I even bought 2 boats of this site and parts and never got screwed!! Thats hard to do these days with all the enternet thieves! Thanx

where is your peak hp??? 670hp at 5000rpms on a n/a engine is pretty unlikely without big cubic inches.

Also, BBlades has a loaner/test program.

I have a 540 big m block ported pro 1 heads 1050 cnc dominator ect... Im getting 674.4 tq @ 4900 & 670.1 hp @ 5600 were is bblades do you have a ph #? Thanx

Prop for 5600rpm.
Look at post #3.
