Fred Hauenstein's 3 cylinder prototype Merc that Michael Werner drove in Europe. It was run a couple times in the US, but only 2 or 3 were made. It was a loop charged motor, maybe 49ci. It never...

Got any more? These are great!

Fred doesn't have his straw Merc hat

Certainly. Please add whatever you can.

I never heard of any being converted to alky. I would imagine that story is due to the confusion of them being used in KPRO in the alky division.

Would you mind sharing that image?

Agreed. Merc's famous disintergrating insulation makes a good distributor/pickup almost impossible to find these days.

Nobody ever got more power than Anthony McC.

There is no 900x ... its just parts. The Speedmaster appears to be a pre-1965 smooth propshaft non-Super type Speedmaster

Some of the other items were true treasures

I had been considering the very same HD carbs for a C-6 hotrod project

There was an earlier Konig 3 cylinder racer before the inline 3 of the 1950's ... the 1930's Konig triple was a radial

I believe these were the first racing triples.

The boat and the prop

That's because the 4's do not have the 120° exhaust tuning increasing the cylinder pressure.

With a good torch, that would take me about 8 minutes

Its been at the bottom of the Salton Sea for 30 years

Exactly correct.


With direct regard to this project, additional tightening of the squish might increase turbulence and increase combustion speed needing later ignition, or it might cool...

I have to double check my inventory, I may have something interesting to trade :)

I am sure there is interest. Any 6 cylinder water tubes?

Well, what would you call 2 newer 500cc Konig's back to back? - probably more than twice that much power?

But as fragile as the Crescent gearcase is known to be ... I'd bet against it in a heartbeat:(

Dudley Malone and one of his friends got ahold of the Crescent racing foot patterns and made a foot...

Early on the CS was rated at 58hp, Henry Johannson says later on they were 65hp. Dick O'Dea stopped making and selling Crescents because Crescent could no longer supply cranks to him to assemble new...

A replica assembled from factory original parts. The O'Dea racers were essentially COPO replicas; made until the part supply was exhausted. It can't be done now because there were no parts common...

Doubtful or not they did. It is a unique project. Unlike OMC, Mercury and Champion, they did not build the C off of any of their production parts.

If you read Swedish and German there is a...

Leek and Strang said there were at least 9 in the Mark25H program alone. I would really like to see that poster too! :)

I think you should read the Brinkman explanation until you understand it.

I agree, the most likely culprit is the prop ... or possibly something else in the set up. It doesn't have to be a speed induced drag problem; there are lots of things that can cause a boat to "hit...

As evidenced by the debates about chamfering, where to measure etc, inspection would be a problem. All is sidestepped with bolt-on parts. Back in 1960, there were a lot more racers that never saw...

The way APBA rules and rule making worked then and now, this would have been unlikely. Bolt on parts with the same internal specs are a lot easier to get approved. There are too many variances in...

There were so many more 20H's than new Hot Rods set up with championship proficiency that at most you could say they were competitive. By 1957 the top Hot Rod drivers were getting things dialed in,...

Had to look thru a couple hundred pages of archives ... rpm range around 8,000

Frank is correct, piston port intake with a rear wall transfer port complementing the side transfers. The cylinders were chrome directly on aluminum, so they were not repairable in that era.
...

Here are the NOA specs of the Crescent Alky

If you are looking for a port map with the widths and contours, you will probably have to purchase a motor and disassemble it.

Per is correct, there is no direct relationship. In truth, they are radically different motors, only sharing the 3 cylinder inline, 2 stroke commonality

The dies were lost in a clean up. Fred Hauenstein says many engineering man-hours were spent looking for the dies in hopes of not having to re-engineer.

I have never seen the year stamped between the model and serial on any others. If someone else has one like this, please share a picture.

The last 20H number is supposed to be 790612 ... so this...

Great info! Thanks!

Can you give me the part numbers of the 2 different driveshafts?



Unmolested 20H's of all variations are rare; easily accounts for any particular person not seeing any particular variation. ...

1,018 from the end of production, at the very tail of the last 3/4 of production - exactly as I would predict, a small skeg motor

There were 4,000. As original equipment, approximately 1,000 had the long skeg.

I like it too

Dick Austin

Merc stopped using left hand twin pinion SSM's at about 140hp because of reliability problems. RH twin pinion units are stronger because the prop shaft gears are closer to the bearings. Later high...

Really nice. Well thought, engineered and executed!

Still interesting to me :)

I do not know. I have seen another separate cylinder Konig clone made in Sweden or Norway, so its not the only one
