New Mercury Shaft Size

[4Speed]

A buddy of mine has a new 2015 150 HP Mercury that he will be taking delivery on soon. I have a few of the small shaft props that I used on my 1993 150 Mercury that I no longer own, would they fit his newer motor shaft?

If it's an optimax 2 stroke, yes it will fit. I don't know about the 4 strokes
