John: I don't know where the SN part was shot. If you were there, Most reasonable people would believe you. I think the outboard part was at Lake Carol in Ill. prior to the race. Johnnie Sanders...

He is the link again of the OMC rotories including the only know footage of the race engine running. I believe it was shot at Lake Carol for a commercial.

Sanders ran the rotary and it was shipped back to Waukegan after the race.

Here is a link to a You Tube video about OMC's rotary engines. Its primarily about the snowmobile, but it also has the only known footage of the 4 rotor race engine in action. The sound is dubbed in...

That would be Windemere '75. The year Scotti was killed. We lost so many boat at Paris, I don't know what Leek would have done and I don't have a clue anymore who was scheduled to drive.

Steve: You might be correct about Beard. I only remember we entered 4 boats, Sanders broke in pratice, and Downard/Posey won the race. I don't remember who drove the 2...

You are absolutly correct. Alan Yaw brought he and Posey to Galvaston. The only time Bobby drove a rotary.

Bobby Witt; Abiline, TX. Drove in Galvaston.Barrel rolled the boat AFTER the race was over.

John:
I was at the race also and if you recall the rotary boats came directly from the Miami introduction and weren't put into the water till the race started. They ran the 15/17 gearcase as the...

They all had RH props. The picture of Scotty's boat at the boat show with the left LH prop is fake.

John:
There was not a gearcase failure at Parker. Both engines failed due to rotor bearing failure because of an extremely lean fuel setting. To my recolection, there was never a gearcase failure...

Appears to be Woods/Jimbo's boat with the 14/23 gearcase.

There is an additional problem. The mazda engine has oil-cooled rotors. The oil is squirted from the crank into the inside of the rotor and then is collected in the center of the end housings and...

Your from Windmere, can't be all bad. Get a BIGGER stick with Shaun and don't bend over.

Come on, you'r supposed to be a rotary man. Those are a couple of Mazda parts stacked up for a picture. No crank, no ct. wt's. no work. Mazda never sold a single rotary, thus no crank and as you well...

Looks like someone has stacked Mazda parts on top of a piece of plywood with OMC carbs bolted on. If you look close, the gearcase isn't connected to anything and a rotary has a crank in the center of...

If you are refering to the picture of the rotary passing the Merc, that is Barry Woods driving the rotary who co-piloted with Jimbo. The Merc driver is Billy Seebold. They lead the race for 5 1/2 hrs...

Guys: With the demise of OMC and the take over of Marine Engineering by Rotax, I suspect all of the old prototypes have been long since thrown away. Most of the old OMC buildings have been torn down...

The 2 versions of snowmobile engine produced were both air cooled, single rotors; 35 & 45 HP. Water cooled engines were never available commercially.

This just about makes my day!:) This just might be the 5th engine I have been searching for. Unless this is the same one thats now in Waukegan. I sure would like to see your pictures!!!! Thanks for...

Racer: Are you sure it was in Sturtavant and not Waukegan? Is it a johnson or Evinrude? There is a Johnson in Waukegan in Marine Engineering and it is the old 2 piece crank engine. If you look...

Wayne:
I can't be sure, but in looking closely at Posey's boat, it appears the bucket is silver, but the top is Johnson gold. That only happened 1 time and that was Windermere, England, '74. Posey...

John: I'm sure you are right, as you had much better knowledge than me. I only heard the stories. My version makes a better story however.

Wayne:
I keep looking at the picture of Barry Woods above and I can't figure it out. To my knowledge, the first time Barry drove a rotary was at Provo, Aug '73. The other pictures and story seem to...

The vehicle had 2 S/N tracks, not 6 wheels. It also had a very sloped front end ala a tank so it could climb over obstacles. It was made by Cushman, an OMC company at the time. They got out of that...

I think OMC felt the jet ski market world go the same way as the S/N market. They had already lost a ton of money in S/N and didn't want to repeat that. Remember in 1969 there were 113 manufacures of...

Guys. The picture of the engine horizontal is correct. It shows the snowmobile engines as they were produced on the assembly line at Evinrude in Milkwauke. The flywheel was one half of varriable...

The first showing of the V-6 was at Paris in 1973; Johnnie Sanders won the race with that engine. It was actually made from 100cu V-4 parts with a new block and head castings resulting in 150ci. The...

I'm afraid the Charlie Strange's and Charlie Alexander's of the marine world are long gone. Some blame Charlie Strang for the demise of OMC. I guess in todays world ecomony the almighty $ is the most...

There was a total of 6 race engines plus a ton of spare parts. The 6 were defined by the shroud, bucket and exhaust manifold. The bucket/shroud sold on E-bay was not completely machined and never had...

Part 4; Additional Rotary Programs

In the 70’s, OMC owned several non-marine companies. Among them was Cushman Vehicles. Cushman was...

How about the time Mouse stole a kids bike and was having bike races in the pool. Then they decided to go in one door of a room, over the bed, even if someone was in it, and then out the back door...

While at a race in Memphis, Jack Leek and his wife had retired early, while the rest of the race crew partied in the parking lot. Mouse and Ziggy got bored (read tipsy) and noticed a Bobcat where the...

The story of the race engine started this thread, but there are some many tidbits I forgot in the story. Like the time we got thrown out of the hotel in Belgium for dropping water baloons on the...

Yes there is a part 4 and maybe even a part 5. I don't know yet as I haven't written it. You know, ambition & time must coincide.

Note Posey's hand. He is covering up the Evinrude logo on Goats jacket. It was cold that day and we all had on all the sweaters and jackets we had. Kukla was turned away from the camara so his...

Side bar on marine turbines as told to me by some X Merc people. Mercury had a gas turbine running as an I/O. Karl Kiekafer wanted to take it for a ride. The water inlet was on the bottom of the boat...

Mercury was indeed working on a rotary headed up by Ben Schafer. I'm told they actually had an engine running. It wasn't a race engine but something like 20 hp. At the time all rotary licences...

The problem with accel. was the 15/17 gearcase. I didn't modify a 14/23 until Provo. Both cases had the same parts as the V-4's, only the outside casting was different to fit the rotary. I don't...

Hey!!! Ann Strange finally firgured out who I was.
