What is more important is the angle of the taper. Find out if the 1" prop has the same taper as you your shaft .
If it has the same taper then the only point to note is it might sit nearer the small end of the taper but there should be no problem.
the taper of some imperial props is 1 in 12 and the taper of some metric ones is 1 in 10 however if you have a 1 in 10 shaft and prop or a 1 in 12 shaft and prop then it should work for you. A good machine shop could alter the taper in the prop to fit.
