swapping props older merc to a newer merc

[samm835]

I have a 1991 Mariner (115hp) that has a good prop, I want to know if I can put it on my older(late70's or early 80's) 90(hp) merc. If it won't swap even I guess I can always buy the inner core portion that will make it fit the 90(hp). The 115 is currently on my pontoon, and I am about to put the 90HP on the toon instead. Thats the reason I am asking. I just didn't want to spend the money if I didn't need to.

It may be an easy swap but The pitch may not be ideal with a 25 hp difference.
