Wanted smaller vintage Konig type racing gearcase

[John Taylor]

WANTED small racing gearcase in good working order.

I am in the process of restoring a 1970s?? Crescent approximate 150cc 2 cylinder loop charged racing engine based on some Crescent 10 HP block. Apparently it had some kind of Konig like small racing gearcase with a 4 bolt mounting pattern by what the tower housing mount plate shows. Gearcase I want to purchase must be in good working order. Send me an email at: catwerx@hotmail.com with a picture if possible and asking price of what you have to offer.

How about pictures again, John ... the motor you are working on may be older than you think ... There were no 2 cylinder Crescent racers in that time period, but there was one farther back

[John Taylor]

When I first got the engine in parts in boxes back a few years you found the pictures of a version of it on some eastern (European) website and posted them as a guide to go by. The engine has basically sat here in the same boxes gathering dust while I did other things. It would be worth taking pictures of and showing when its complete again but not the apart state its in now. That is why I am looking for parts to complete it on the long term. IP a small racing gearcase.

[Mark75H]

Pictures of the parts would confirm what you have ... or determine it is another brand ... such as a Dolphine etc

[John Taylor]

There is no doubt that it is a Crescent. Its too bad they didn't build a little 3 cylinder version of it because the engineering is so much like its big 500cc big brother tripple. It even uses a press together crankshaft and needle bearinged big and small ends. The only departure is its carb that is mounted over a front and central pyramidal cast in crankcase reed valve body feeding the 2 halfs of the 2 banger. Still, I need a little racing gearcase for it. The tower it sits on is fabricated steel tube with Mercury clamps and what apprears to be a mount for a four bolt small Konig gearcase. Some of the picts here already in the Anzani threads of my garage the tower is seen sitting on the floor without the engine on it. I am sure it must be Konig LU, what else is four bolt?

I'm playing with building a D Mod, and have been looking for a Hatchet Yamato Unit....I called Dave Mayer as I thought I saw several in his stuff...Seems anything I want to buy, he ain't selling...But he offered me a 12:15 Konig unit for $650....


Post a picture of what you are looking for and if Mayer's price is close....

You mean the "140 Racer" ? A little beauty! Introduced to the public in '61, rated at 12 hp (later ones 14). It does not have much in common with the 140cc 8 hp fishing motor introduced in '59. Me too would like to see a picture...

[Mark75H]

John, that description does not agree with the picture of the 2 cylinder Crescent. Pictures of the motor you have would still be helpful in figuring out its identity.

Here is the picture from the old Classic Boat Racing section of SWEDISH RACEBOAT ASSOCIATION site

As you can see there is only one bolt in the front ... probably a 2 bolt tower.

Matts, where did you come up with the info you have on that motor? Is it on the Crescent site?

[Matts]

Sam, I have not read it on the net. What Crescent site are you referring to?
The red motor does not have the beautiful factory exhaust.

[Mark75H]

The one that Carl-Eric Zander had put together a few years back. It is now falling apart, but hasn't been deleted from its server. I can't find the correct link to it right now.

[Matts]

Ok, it is the home page of "Nymans Vänner", a site dedicated to the old "Nymanworks". Try google "nymans" an d you'll find it. They have put together some info about the company and their products. Not too much about the outboards, and everything is not correct (they are very well aware of that and it's mentioned as a 'caution' on the first page). The Zander article is still there. The "140R" is very briefly mentioned, he writes a lot more about the CS500. Most efforts were concentrated on the 500 back in the heydays. Everything is in swedish:p

[John Taylor]

I will have to post the Crescent block's picture when I take it on the weekend.

[Mark75H]

Matts there was another site that Carl-Eric or Gert Lowinsin worked up that had a lot more detail. It wasn't just an article by Carl-Eric, it was several pages. I saved and translated parts of it. It claimed that Gert Lowinsin and Rolf Miles were responsible for Crescent's 2 cylinder 140 R motor and that it was produced before 1960. I don't think there is that much detail on the current site. (I found the old link and it is completely gone; good thing I saved it.)

[John Taylor]

Pictures of little Crescent 2 holer loop block (140cc). Chromed cylinders and all. Also the tower flange adaptor for Konig gearcase?

[Mark75H]

Yeah, I'm sure that is a Konig tower and it sure looks like a Crescent powerhead ... but I'm not convinced it is the 140 cc Crescent.


I'd be very curious to learn the bore and stroke of that motor ... because I have a theory about what it might be ;)

[John Taylor]

I am not sure it was a racing motor to start with. Just like the Crescent 500 Super C and Alky motors there was the Crescent loop 3 cylinder ski / fish engine as well and they look similar if not the same base block wise. I did not take too much for someone to hang pipes and a Bing carb from the little beast on a steel tower/clamps at standard height. It uses an aluminum flywheel with rope place and phelon flywheel ignition system that looks factory installed. Pretty basic and good working. I will have to measure the bore and stroke. Another reader suggested it's base block is a 9 or 10 horsepower late 1960s or early 1970a Crescent. Good question? It is so hard to find out anything about them these days.

[Matts]

John's pictures shows a 140cc Crescent/VP/Archimedes 6/9 hp fishing block of '69-'79 model year...a successor to the old Crescent 8 hp. In '75-'79 they used the Phelon ignition on this motor. Internally it surelly looks bone-stock, too.

The 140 Racer made its public debut at the Stockholm Boat Show in march '61. The bad picture is from a magazine test-drive article of april '61. (no food for a Crescet historian) If I had brought my digicamera with me when I looked in a certain photo album you'd had something to drool over:p Next time I will not forget, I'll be back on it. (may take a year or two)

[John Taylor]

Thanks to the advertsing I am entertaining 2 lower units to choose from for this little 2 banger. One gearcase is from a Martin racer and the other one is an older Konig with the center to cigar water inlet. Thanks peoples.:)

Through this thread advert I managed to get a Konig gearcase for this engine's needs. Thanks all! :)
