He's either replied to the wrong place or thinks that's enough of a question to yield a useful answer. ;-)

The correct answer would be 'whatever was there by design' as the wrong type of replacement could either damage the drivetrain (if too strong) or shear prematurely, leaving you in a vulnerable somewhere.

I posed the same question in the same form in duck duck go and got a plethora of answers. (probably same in google) Don't know why I posed the querie in this NG first

Whereabouts? does it see seawater? That would be a good reason for using a high quality brass (or other cuprous alloy). In "dry" locations mild steel is the usual thing: cheap, convenient, breaks relatively cleanly. Stainless steel is less suitable because it is relatively ductile and work hardens, so may deform but not fail cleanly.

I would say that subject to suitable corrosion resistance (and galvanic compatibility with the other parts) the other materials properties are not particularly important.

Well are we talking outboard as in a boat? I'd have thought somewhere a spec for whatever it was has to be found, end of story. Brian

I believe so Brian.

Quite. ;-)
