In line six Carniti Racing Outboard/Angelo Vassena Paris Six Hours 1969/70
Here is some interesting outboard history. Back then Angelo Vassena of Italy was working for the Carniti Outboard Factory in the northern part of Italy.
Well..Angelo was also one of the best power boat racers ever. The Carniti factory developed a new in line six engine for the Paris Six Hours 1969 and -70.
The ON class was normally dominated by Mercury and Evinrude/Johnson..new competition is always good but Carniti later pulled the plug for the ON engine.
Yes..this is Angelo Vassena above in the boat #26 with the Carniti engine.
