Federal Supercup Ni-Bral 14X16 questions?

I have a Supercup Ni-Bral 3 blade 14RH16
It was a spare when I bought my 1990 supra ts6m.
It ended up in my garage and didn't go with my boat when I sold it. Now I have it and wondering if it would make a decent spare prop for my 07 Outback?
But then I think my Moomba is the opposite rotation as my Supra was?

Anyway.........
1.) can it be used on my current boat?
2.) if not, why?
3.) what is it worth (I looked up retail new is $573)
4.) the 14x16 is made for what application (wakeboarding, skiing, high-altitude, ect.)
