Renato Molinari and his black #18/Molinari/Evinrude F1-V8. My guess is this is from a special race event in Italy 1984
Thanks you Antonio Collini for the pictures.
Pretty interesting comment from Roberto Bigi about the three pictures above. Here is a picture from Clear Lake outside Houston, Texas 1983 when Renato raced the Unlimited Hydroplane class with 2 X Evinrude F1-V8 engines.
Roberto Bigi The black boat used at Como lake by Molinari was exactly the same boat used in Houston with 2 engines for the Unlimited world championship.
Here is why I am pretty sure this is the twin F1-V8 boat Renato raced in the Unlimited Hydroplane race at Clear Lake outside Houston 1983.
1. You can clearly see how wide the boat is in the rear under the rear boat cowling. This is done to get a wide transom to fit two engines. The second picture show a regular single engine Molinari boat from same year.
2. The single engine installation on a twin engine transmission forced Renato to make new much wider steering bars.
The second picture show standard OMC F1-V8 steering bars from same model year.
