Guys: With the demise of OMC and the take over of Marine Engineering by Rotax, I suspect all of the old prototypes have been long since thrown away. Most of the old OMC buildings have been torn down and the places where this stuff was stored went with them. As of last summer, there were 5 rotary race engines surviving; 2 in a private collection and 3 at BRP. I was told when Rotax took over, they ordered all the old OMC stuff to be disposed of. I have also seen a picture of a prototye rotary outboard, but believe it was of a later vintage based on the 650cc engine. Us race guys, both old and new, would like to see some of the racing outboard history preserved and be available for public viewing, but in the production sceem of things, prototype engines like the rotary has little meaning to production outboard history. Rotax has a history in go kart racing so maybe someone there will at least see some of these engines get preserved for public viewing; lets hope so.
