TOPIC: Help Tracking Down A Merc 650

Ok, after years away from my weekend warrior passion of classic FG boats, and regrettably selling my Glasspar Avalon, I need help!
Trying to track down a restored/rebuilt 650 mercury for my new project. It's a 1961 Renken Overnighter. I would like to keep it period correct. Is there anyone out there that can point me in the right direction?

I miss these forums!

As always thanks!!
