on my Alpha 40, I was wondering if i could use a 2 bladed prop instead of a 3? I busted one up last week and went to the LHS and they have the 3 blade prop sold out and have tons of the 2 blade.

Just wondering if it made any difference? just as long as I use the right size prop? and what would it be, same blade length or does it need to be bigger, smaller?

I assume just have the prop be appropriate to the Engine?

Thanks
