The #754 Molinari boat above is a similar boat to the first boat built by Renato after he left Mercury for big OMC late 1976. Came to the USA just before Parker Enduro 1977. Renato used Bob Hering as his co-pilot and also Bob's USA race #457. This was also Renato's first race as an Evinrude driver and Bob & Renato took the overall victory in Parker 1977..👍

Interesting mix.......#45 Bob Hering / O Gradys potato chips Hering hull. #94 Steve DeSousa EZ Loader trailers Seebold hull. As this "mix" continued it was rumored that the fuel paid for by OMC in the series was adjusted for a lower octane rating. The V8s could run on it just fine but the fuel injected Merc 2 liter champ motors would burn pistons. Kinda forced the Merc guys to bring their own fuel supplies.

Well..stick to facts now please.."Nine Mercury 2.4 litre V6 powered drivers and one Johnson V6 powered driver had joined the fray in the hope of earning a slice of the $50,000 prize money"
A few weeks later 1984 Merc used the 3.9 liter V6 and the twin powered V6 (wizard)..but for now we stay in Minneapolis

..the report is coming later and you can clearly read a lot interesting "engine stuff"
This race was the first one after Stockholm GP and OMC asked me to please send your #8 boat with us to the two US races.
I told them No thanks..I needed a break from racing for many reasons.
First picture is #1 Cees Van Der Velden in his 1984 Velden boat. (in my opinion way better looking)
#97 Tom Posey is driving the 1983 style Velden boat.

Lars did you take 754 out on the lake for a spin?

#10 Tom Percival driving his Hodges in Stockholm GP 1984.
Tom also skipped the two US races after Stockholm as I did..so this comment today by his daughter is very sad..but just the way it was..
Katie Percival
Probably one of the last photos of him racing https://static.xx.fbcdn.net/images/e....5/16/2764.png… thank you for sharing https://static.xx.fbcdn.net/images/e...5/16/1f60a.png
The next European race after Minneapolis & Pittsburgh was Liege, Belgium and that's when we sadly lost Tom in his accident with Fabrizio Bocca.
https://www.screamandfly.com/attachm...9&d=1647468729
Not many people know this but at the Paris F1-V8 race in June 1984 Tom Percival and I was racing for the same sponsor.. “International Travel Card”.
We did lots of promotions together for “International Travel Card” and I got to know Tom pretty good.

I don't have a good picture of my #8 boat in Paris 1984 but here is one from a video. (below)

I always wondered, even w/the Unlimiteds, was it that it had no effect or you couldn’t set it it up to react fast enough??

I believe the wing on the Hodges was used for downforce, the Hodges had quite a lot of lift, I know my ON Hodges did.
Well..maybe but that would only work in one direction on the race course..the wing must be fixed and not changed by the driver.Quote:

There was a time in F1-V8 racing when some drivers including Renato used a front wing but did not work and by 1985 all the front wings where gone including the Hodges boats.

It seems the F1 boat builders agree the front wing is "pretty useless".
However Unlimited Hydroplanes use a Canard Wing which they activate up & down for optimal bow attitude.
UH need it because they do not have stern power-trim angle of attack adjustment, like the F1 boats.

A perfect balanced tunnel boat is way better and the power trim is the answer..
The 1984 F1-V8 World Champ Renato Molinari never used a wing that year.
His #18 Molinari/Martini/Evinrude V8 was balanced perfect.
This is from Stockholm GP 1984.
https://www.screamandfly.com/attachm...7&d=1647711639
This is Renato in 1982 and he did use a wing on his #165 titanium boat..not sure why but later ditch the boat when he did not win the World title 1982. (Renato also used wooden boats without a wing 1982)
https://www.screamandfly.com/attachm...8&d=1530102034
Tim Butts experimented w/fixed wings on his Pro/Alky OB 3 point Aerowing hydros.
Was before my time but he told me he could totally change the attitude of the boat but did nothing for lap times.
Of interest though, those boats had no power trim and what made his hydros “Aerowings” was the leading of the deck, between the sponsons was radiused like the leading edge of an airplane wing.
He mounted his wings aft, from the outer chines, at an angle up to the top of the transom.
He did it to lift the transom and fly the boat, which he said it did.
Said he could fly it all the way around the course.
He said the power used to create the aerodynamic lift was greater than the speed increased from the reduction in fluid-dynamic drag though.
Funny part though was, he said the APBA banned it as they did not allow “aerodynamic lifting devices”.
He asked them, then how does a hydroplane work and it is allowed ��
OK..just to twist the wing discussion..:)
Same powerful #18 boat with and without wings..(2 X Evinrude F1-V8 engines)
Molinari racing in the Unlimited class 1983.
Some says the rear wing was to make the minimum length..but I don't have the correct answer.
