Pitch Vs degrees and blade angle
Is there any correlation between pitch and the angle degree?
I have a few sets of props laying around and I have no idea what the pitch is on them. They vary from 39* to 46* when I measure the blade angle.
What I am trying to get at is if I have 3 stock bravo1s and knew the pitch of one of them could I get close to what pitch the other 2 are by measuring the blade angles. They are all the same brand props so the blade geometry is the same.

There is correlation to angle and pitch. We don't use angles because pitch typically varies in its progression. The leading edge is lower in angle than the trailing edge.
Are there any part numbers on the castings?

Thanks Brett,
There are some numbers on them, I have 3 sets of Spenelli's that I really like how my boat handles with them on. I was just curious on the different pitches they are. I own them so they are what they are. I was just trying to get some referencing so if were to sell them down the road. Right now I can only reference the RPM differences I see when I run them on my boat.
I need to get one set repaired for some nicks on the leading edges. Maybe a repair shop could tell me then.
Thanks

I ran many of their props on my Checkmate 20 years ago.
They often were the best for various reasons and goals.....
I still have many of their blade templates.
If we can clean them up or computer diagnosis them for you, let us know.
