I got this picture from the pit just below the Eiffel tower at river Seine.
Interesting because the red #16 Molinari boat is using one of the first OMC 3 liter, looper V6 with fuel injection and Johnson RS cowling.
The drivers of the #16 is Johnny Sanders and Jimbo McConnell.
USA

Next blue #12 is a Molinari boat also using one of the first OMC 3 liter, looper V6 with fuel injection and Evinrude CCC cowling.
Drivers of the #12 is Renato Molinari and Tom Posey.
Italy/USA

The yellow/orange #15 Molinari/Bosch boat is powered with a Johnson RS 2.4 liter V6
The driver of the #15 boat is Erwin Zimmermann of Austria, I do not remember the second driver.

Next to Zimmermann is a boat you can only see the front and the bottom is covered up..
It is the #11 Molinari/Saffa boat powered by a Evinrude CCC 2.4 liter V6
Drivers are Angelo Vassena and Lars Strom.
Italy/Sweden.

This was for Vassena and me very interesting..Our first big race in the OZ class. We where very fast at testing but the OMC racing boss Jack Leek told us to use a way bigger pitch propeller to keep the RPM down. The reason was to make the race engine last six hours.
Well.. made the boat harder to drive but we made it to the end of the six hour race. Finished fourth overall..Second best OMC in the race.

Thanks again to Roberto Bigi
