Was there ever a discussion about putting a water tight access panel near the 4th carb? I remember something about one of the rotaries dropping out of a race due to "sabotage" with a loose carb? Sure it wasn't the number 4 carb coming loose because nobody could get to it? Was the clamp bracket unique for a rotary or adapted from a V6?

Yes. The black manifold in the picture housed 4 equal length pipes. The blue part in the picture is a collector where all 4 pipes dumped. The length was determined by dyno runs starting at 24" and cutting off 1" at a time. Remember people including me were in the dyno room during the runs. Anyone who heard the Mazda IMSA cars run knows the sound energy of these engines. Now imagine being in a 12 x 12 room while it was running.

As a matter of fact, screw in plugs were added to the bucket to access the jet on the 4th carb and the 4th spark plug. Some where I have a picture where you can see the white plugs. There was no way to access the mounting bolts for either # 3 or 4 carbs while the engine was in the bucket. As far as the loose carbs in the '74 Paris race, all 4 carbs were completely loose. that's 8 nuts with star washers. I personally adjusted the carbs on the dyno and could have easily determined if any one of the carbs were loose. It had never happened before or after. Not even 1 nut, let alone all 8.
The V-6 didn't exist when the rotary was developed and is actually why the rotary was discontinued after it was. The clamp brackets were from the V-4.Last edited by Rotary John; 02-07-2023 at 05:12 AM.

In the early 70's the refueling & start barges were secured next to the river bank.
In this photo to haul all the refueling equipment and fuel to those last barges would be a killer.
I remember my arms were tired hauling fuel from the truck to the refueling tank on the barge (manual labor it was in the 70s).

You probably know better, but my recollection of the rumors around the time just before the bankruptcy is OMC sold all their racing inventory and design rights to Sea-Way so it would survive. Then there was some uncertainty or confusion of who owned some of the inventory stored at the Velden shops. Some stayed in Holland and some came back to the US. I heard it was all offered to at least one other dealer as well but Sea-Way stepped up and saved it.
