Speaking of Engines

OK, another one from the junk box. 

Given to me many years ago, I haven't a clue as to what it is.
It's about the same size as the MERCO 35.
The only markings are two "Ms", one above the other, on the bypass port.

So, what is it? Size? Type?

Other than the venturi shape and fins, the case looks allot like a copy of a K+B Torpedo or a Johnson.

Hi Bob,

From the pictures, it looks exactly like the Merco Red Head .35 you posted....... except for the markings of course!

I would almost be willing to say it was a European/Soviet copy of same.

There were a few versions of the "29 "too . . .

Someone did a combination that was pretty quick for Vintage 'B '.

Put a stick down plughole to measure the stroke ?
Blunt tooth pick, mark tdc & bdc . There you have it .

What are you talking about?   
What will measuring the stroke prove?

There isn't any difference externally between a Merco 35 and a 29, except for the 29 and 35 on the castings! Whatever you have isn't a Merco!

Regards,

Andrew.

Agreed!! Definitely NOT a Merco.
It has a one-piece cylinder casting like the Fox and Merco.
The mounting holes and case width are identical to the Merco.
It is .3 ounce lighter than the Merco, with a shorter front end.

I wonder what M
                    M means.

ps - isn't it neat to find stuff like this?

Hi Bob,

I'm still thinking "Merco Clone".  Doesn't help answer the question directly, but then I am not aware of who cloned engines back in the day.  I know it was done, just not who did it! LOL!!

Merry Christmas!

I think the Iron Curtain countries did a lot of cloning of various engines.  But then for all out speed and racing they developed there own.  A lot of engines were made that never came out of the Iron Curtain countries.  The fall of the wall allowed some individuals to start their own businesses.  To my eye tho the engine in question looks more like a rough Veco copy.

You could be right Doc, but the quality looks a bit high for that sort of instance. That said, there were some high quality engines made behind the curtain, so its a real possibility.

It is an early 70s French Micron, probably a 35.  Micron built top notch engines. Muffler ears ala Fox were added about a year later.  I'll confirm displacement as soon as I can.

MECA has engine answers!

PS - Now you know it a Euro engine, be sure to use metric toothpicks when making maeasurements!

[Robert Zambelli]

THANKS, Bill.

The engine is new. I will break it in and try it on my ARC Smoothie.

[Bill Little]

Well, I wasn't too far wrong on my guess.  French is European! LOL!!

Bob, please take a couple pictures of the Micron and the RH Merco side by side.  I would like to see the differences other than the prop drive washer.

Doc, I always suspected that the Veco Stunt .35 was the basis (design wise) for the Merco .35RH.

Merry Christmas!

OK, the engine you have is a .29.  Brian Cox, the MECA engine guru in France, wrote the Micron index in Engine Collectors Journal and provided the follow:


The engine you have is a very nice sport/stunt .29 (made from 1961).
> There were also a .35 (blue head) and a .45 (green or black head) made

> externally, apart from the head anodizing.

Oh yes, MM is "MICRON MOTEURS"

Merry Christmas from MECA!
