Prop experts opinion needed

[GlennN]

I currently have an aluminum 11 1/8 X 13 prop on my ‘99 640lx. It has some damage from previous owner. I’m looking to replace it with the exact same prop measurements and same brand since it seems to perform really well. In shopping the brand I currently have I’ve found I can do an exact swap in aluminum or upgrade to a stainless at only a $60 difference. Here’s the question my partner in crime is bringing in. Since there is no or less flex in stainless how much of a difference in performance could or would this make?

when I had my Opti 115 and switched alum to SS, I dropped from a 19 to 17 pitch

You should get a better holeshot. The other thing to think about is if you fish an areas where you think you may hit something, stick with aluminum.

I am assuming that you have a 50hp?
