Tiller steering?

[ParmaBass]

I've been getting different responses from various online marinas and motor parts salesmen. I need a tiller motor for my boat and I'm having a hard time finding one that suits my needs. Some tell me only newer motors (1993 and newer) can be modified from remote steering to tiller and some places are telling me every motor can be modified to tiller steering. I found a motor on Ebay it's a 1972 Mercury 40hp remote steering, anyone have any info for me?

Thanks guys!
