WTB: Yamaha 50-70hp two stroke

I’m looking for a clean, later model Yamaha 50, 60 or 70hp 2 stroke with 20" shaft.
Must be in excellent mechanical condition. I can handle paint or sticker defects on the cowling. No rigging needed as it will be converted to a tiller.
Please send me a PM with details. Located in Columbia and willing to travel.
Thanks
