There was 20 ON class boats with OMC engines (Evinrude/Johnson) in the Paris 6 hour race 1970.
13 ON class boats was powered by Mercury and 2 Carniti powered boats.
Here is the complete entry list for the race.
The #26 ON entry with Carniti power was pretty interesting. In line 6 with cylinder heads.
