Here are 2 adds from Popular Mechanics of March and May 1908.
Invincible Motors was a Sydney Australia based company whom imported castings from the US for some of their engines up until 1929, the rest were locally built. They also imported "job lots" of complete engines.
I have never been able to discover whom supplied the imported castings, altough I have seen a couple of Invincible badged Fairfields.
Perhaps somebody could identify the engine depicted in the adds?
Thanks in advance,
Mark S.

H.D. Baird was the designer and maker of the St Clair Marine engine that came on the market in 1905, like many inventors running a business was not his strong suite and the company was sold to Gray-Hawley in 1908, many companies bought the rights to use the design and market it. Invincible was a Chicago, Illinois based company but also had main branches in San Francisco, California and Sydney, Australia !
Other Companies that used the design- The Belle Isle Boat & Engine Co., merged with Collapsible Steel Form Co. in 1911 and became The Concrete Form & Engine Co.
Monarch Mfging Co.

Thanks Richard,
That's great
I'll get some pictures of later engines, 1920's which are mostly four strokes.I'd like to identify their origin.
As well as Sydney, Chicago and San Francisco Invincible had branches in Adelaide Australia and likely St Paul in the US.
The St Paul branch was later and most likely had something to do with Invincibles move away from marine engines to road vehicle engines and parts.
Konrad Boehm was the founder and owner of Invincible motors and lived in Sydney although he had close relatives living in the US. They were orginally Austrian immigrants in the late 1800's.
Best Regards,

I have looked for years for a picture of the Belle Isle engine with the intake side showing a mixer or carburetor. Have had no luck. My wife's Belle Isle has a unique float feed mixer which I have only seen one time on an outboard at Mystic back about 1995. Its owner had no idea if it was original or not. |
