My guess is 201 is Ken Stevenson and maybe Bob Hering in the 3 cylinder boat…He won the UIM World OE title 1978. The race was run in the USA.

Thanks for the picture/poster my OMC friend.

This is interesting picture because Barry is leaning forward..meaning his Molinari/Nordica/Evinrude V8 did not have a safety cockpit..
One of the reasons I did not like to be strapped in..terrible feeling..you could not balance the boat by leaning forward anymore.
Renato was not in to developing safety cells/cockpits.

Fantastic result.

Wow..this is a very unique info and facts from Italy.
In 1981 Renato Molinari installed the Evinrude V6 2 liter looper fuel injection powerhead as an inboard and hooked it up to a stern drive with racing lower unit.
He won the UIM R3 2 liter inboard class World Championship same year.
See..now we know where some of the very unique and powerful OMC looper V6 2 liter powerhead ended up.
Thanks for picture and info Roberto Bigi.
