Increase/deacrease prop pitch ?
I have a brand new Bravo1 22p lab.
The thing is that it's to small and I need 24p lab.
Is it possible to bend it up to 24p?
I don't want to bend it if a standard 24p lab will give me better performance.
I have a Rev4 lab that I added cup ,but now I can't turn it and it does not grip as good as my Bravo1.
Can I decrease the pitch on my Rev4 and still make it as good as a new one?
Let's say my is a 25p lab with extra cup,maybe it's 26p now.
Can I bend it back to a 24p with extra cup without taking the diameter?
I'm trying to find the best prop for my Airshiprib/Cougar R8 with Mercury Verado 350SCI.
Now I have 5 props that don't fit ,and props are expensive and hard to get in Norway.
The Bravo1 made it more stable,better grip and better seakeeping,but I think I need to do something when I get the right pitch to lift it more out of the water to get max speed.
It's fun to get 7000rpm in about 10sec,but missing 8 mph :-)

Thank you Griff.
Then I know I have to buy one more prop.
I talked to Bret last year and we decided that it's better to make my prop here in Norway/Scandinavia because of the shipping.
But my problem is that my props are to far from the right size to start working on.
I will order a Bravo1 25p lab and I will go from there.
I understand now that a 25p Bravo1 is actually a 24 pitch.
Does anybody know the best Rpm a Verado 350SCi shall run on at highest possible speed with one person low fuel/weight
It stops at 7000rpm,but a guess it's not much torque at that Rpm so a have to increase the pitch up so I can get the rpm down where I get best rpm/pitch/speed,but how low?
I have heard everything from 5600-6800rpm.
It's 300rpm/pitch but it's not easy to know what size to start with. 24,25 or 26P? That's the problem when a prop cost 2600$ here and no return.
