Your spare was designed for a “modified” 170 which I guess means it’s putting out more than stock HP. How much more than stock they don’t say.
Impellers/props are tricky. That’s why “modified” planes have variable pitch propellers. More hp the more variable helps. My guess is you won’t be able to tell the difference except for a small loss of RPM and speed at WOT. Put it on and try it and report back.
