Very interesting outboard racing history from 1974. The OZ class World Championship race in St. Louis, MO had 13 boats ready to race. 5 with Merc V6 T-3 power, 2 OMC Rotary’s, 2 Johnson V6 Stingers and 4 Evinrude V6 Super Stranglers.
Barry Woods in his Scotti boat powered by the Evinrude Rotary was by far the fastest boat. Won the first two heats but barrel-rolled in the third when he was leading handing the victory to Bob Hering.
Now we all understand better why Team Mercury successfully was lobbing so hard to ban the OZ class in the Paris 6 hour race later same year..!!
