Soriano du Puy (and more), Deutsches Museum (Munich)

[Smokin' Joe]

The Deutsches Museum in Munich is heavily populated by technical displays, including a small outboard display. Here are a few nice items:

Photos 1-6: Dr. Robert Richter's step plane with supercharged 4 stroke Soriano outboard. With the quasi-tractor gearcase the rear prop only eats the wake of the forward prop (elementary hydrodynamics suggests that it couldn't work as well as a single prop, but hydrodynamcs is nonlinear so actual tests are useful). Note the automobile steering wheel.

Photo 7: 345 cc/70 hp König. Did anyone get more hp/cc than Dieter König?

Photo 8: Laros 2 stroke, Milano, ca. 1930.

Photo 9: 1996 Evinrude 150 cutaway with direct injection, donated by W. Hellmich of the Provenion company (Munich) that made the Ficht (?) system during 1990-96.

Photo 10: Joe McCauley, Cornelia Küffner, Finn and Hans Küffner-McCauley after a very enjoyable Jan. day at the museum. I've visited the Richter boat every time I've gone there since 1996. Hans and I have a 1981 Evinrude 15, shipped from Houston, that we plan to rebuild completely in our cellar workshop in Austria this winter.

The dual prop Soriano was very successful. For many years it was the world's fastest outboard.


No one beat Dieter for very long while he was alive, that is for sure. Power has about doubled since that motor was made.

Dieter was a worthy adversary; well respected by everyone at Quicy Welding, and we kept him at bay for quite a while.

I'll never forget the look on his face when I caught him sneaking a peak at an
"A" looper we had disassembled in our trailer.

I slipped in behind him and said, "Runs pretty good doesn't it'?

He smiled, said "Ja" and walked away.

Dieter Konig, another of the greats in the pits at Lake Paradise!

[Smokin' Joe]

I'm glad to get a response from Qunicy. How much hp/cu. in. did the Qunicy loopers pull? Do you know if O.F. had any influence on the design of the wonderful OMC 75 looper (50 cu. in.)?

Best wishes,
Joe

What motor pulls 140 hp/345 cc? Wan't aware of that!

The Arens and Rossi 350's; the 500's are looking at 180-200

[Gene East]

When I left Quincy Welding May 20, 1973, We were pulling 3-4 HP per c.i.
Obviously the Z's were much stronger!

Paul could best answer that question as well as the question concerning Chris's involvement with the OMC.

If you are surprized that I can remember the exact date I left QW, I started working for QW April 10, 1962.

To me those are dates as important as my birthday.

I made more money other places, but Quincy Welding was the BEST job I ever had!

Chris and I had a long phone conversation shortly before he passed away.
He asked if I would like to turn back time and do it all over again.

My response was, "DAMN RIGHT"!

Great pics and info Joe. I probably read the answer to my question before when info on the Soriano was posted, and I am guessing the rear lower unit shaft operated in left hand rotation....correct? I understand what you are saying about running in the wake of the leading prop and agree about the hydrodynamics. Also surfacing props at high speeds don't churn up the water as badly as a fishing motor, and I guess they proved it would work just fine. But my second question is....they didn't run that prop backwards like in the pic did they? I'm guessing someone at the museum just put it on as a mirror image of the leading prop, because I can't see how it would work that way at all. Or am I missing something?

[Smokin' Joe]

I understand you perfectly. I raced OPC (NOA in Tenn.) as teenager in the late fifties and again in 2nd childhood 1977-1985 in both APBA and NOA. By 1985 it was dead for me, big money and big boats had taken over. Paul Allison said, and I agree, that he and I lived through the golden age of boat racing (1955-1981). My parents were Mercury dealers 1957-1961, so O.F. Christner and Qunicy Welding works were of heroic stature for me a that time. I once ordered a spring loaded Qunicy crash throttle.

Really glad to make contact with you,
Joe

I noticed that the rear prop is on backwards, too. My Dad used to tell me stories about these engines and how strong they were. The front prop is made for fitting to the front of the lower unit. Someone might have just stuck a prop on for display.

[Smokin' Joe]

Wayne, I think you're right, counter rotating props

http://www.soriano-outboard.com/11357.html

with rear prop on backward in the photo! I took inventory in our Houston garage in fall. I have enough parts to build (more than) a complete 3 cyl. 75 powerhead, ready to bolt onto a downhousing and run. Got enough gearcase parts to build multiple gearcases, minus housing and driveshaft. So I'm buying a downhousing and gearcase housing with driveshaft to put together a motor (need to find an Evinrude 75 cowl) . I haven't the foggiest idea what I'll do with it afterward. Maybe just put it on a stand and look at it, like your König. I simply love the old outboards.

Best,
Joe

Charley, I just replied to Wayne about that. What motor is that in your photo?!!

Joe:D

Dad told me of these units and they were solid drive shaft supported on both end with a single pinion. If they are run in this position it will turn up big rpms and go nowhere.
The engine in my signature is a 44 Quincy Flathead. This is the one that made my DOH Aerowing feel like it was about 3 feet too short.

[Smokin' Joe]

The torn down gearcase in

http://www.soriano-outboard.com/11357.html

looks like 2 separate prop shafts.

I guess the engine changed over the short time they were raced. My Dad's stories started in 1929-30 and he was out after WW2 broke out. Seems to me it would still be reversed as far as the rear prop.

[Smokin' Joe]

Had I really looked then I'd have seen the Mercury crankcase, if not the timing belt.

Yeah, Joe & Charley....the photos show it like I expected. Right hand prop in front, left hand prop in the rear, with the leading edge of the blades facing forward. Somebody either just stuck that prop on the lower unit at the museum without paying attention, or didn't know how it went and tried to make a mirror image, or just maybe playing a joke. Two separate counter rotating prop shafts and it would just need the one drive shaft to make that work. You could swap prop shafts, but not props. Somebody probably "borrowed" the left hand prop that was originally on the motor. It was hard to tell if those brass props had tapered hubs, but it didn't look like they did. Maybe the one at the museum was for kilo runs.

[Mark75H]

A single drive shaft drives 2 prop shafts, a front shaft and a back shaft, running counter rotation to each other ... like the Volvo and Mercruiser stuff in modern times

These motors dominated D and then X class racing from the late 1920's until the early 1950's ... they were not a flash in the pan.
