Spinners are made to accomodate the smallest possible prop that they figure will be used on that kind of spinner. One can always make the holes bigger (and thats pretty much always been the case for me) but if they were too large to begin with, you couldnt really make them smaller. Im pretty sure there isnt a 2 1/4" spinner made that will just fit that wide a prop. The exception would be aluminum spinners from companies like Tru Turn that custom cut them for certain props. But those would be way more expensive.
