Prop Shaft - Bronze or SS?

[Steve]

I know everything about my prop shaft - or so I thought.  Now, I think I know that the shaft is stainless steel, but am not sure.  Am ordering a folding prop, and Martec now has available a SS folding prop that I'd like to have, but only if the shaft is SS as well.  Does anyone know for sure?  Mine is a 1988 model.  Thanks in advance....
