1973 Ski Doo Olympic 1973 Skidoo Olympic 399. Totally rebuilt engine, brand new bogey tires and bearings, carbide runners, ski spreaders, track is in decent shape. Needs a little ignition work. Moving south to warmer weather and don't have time to tinker on it anymore. I've put a lot of time and money into this sled. She'll make somebody a good ice fishing sled or nice addition to a collection.
