Mercury Prop Identification

[fimpel]

I've searched Google and maybe someone can tell what or where to go.

I have 2 Mercury props that have different blade designs. I wanted to know what they are and why blade designs are different.

Brass/Bronze prop
48 32744A3 21P

SS prop
48 72762A-4 19P

Re: Mercury Prop Identification

Perhaps some pictures would help.Perhaps a google search for prop design,prop theory etc may answer your question.I put in brass prop number at google and found an iboats post from 2002 regarding vibration and prop of that number.Not any help but at least some result.You might also search for raker props and lifting props etc may be pictures or description I did a quick search and a couple of discussion areas did come up.

Sorry for the delay.

Heres the pic of my brass/bronze prop.

Heres SS prop. I couldn't get a good pic without taking it off. Hope this helps some.
