I measured the large hole and its 1"
This is quite lame, on my receipt it says no returns on propellers but I sure hope they will give me my money back because he clearly gave me the wrong thing, its even documented on the receipt as a 1 1/8 and 1" on the box. not only that but I was assured it was new and this one actually looks like it has been repaired,on one of the edges. Maybe a new prop isn't in the cards for me and I should just get my stock Acme fixed and wait to go out for a week...
Thanks again Art and Karl, I appreciate the help
