The first 2.5 hp Archimedes BS motor arrived on the market in 1912. The first opposed twin outboard! The first motors were battery ignition. The company soon turned to magneto ignition.

This page is being compiled by Emma Craib, who likes to research things but is not an outboard collector. Mistakes probably will be made...so please send me corrections if you notice anything wrong. Information and photos happily accepted, too!

Archimedes BS, (1911)1912 -1919

  • the first BS had battery ignition, but soon (1913) offered magneto ignition
  • BS-1 - 1912 -1919 - 2 1/2 hp
  • BS-2 - 1914 -1922 - 5 hp

Archimedes ABEA, 1916 - 1921

  • two tillers!

Archimedes BSO, 1918 - 1920

  • same as BS, 2 1/2 hp but with reverse

Archimedes BSO, 1918 -1920

 

Archimedes BST, 1919 - 1931

 

Archimedes BSOT, 1920 - 1931

 

This booklet was published be Archimedes in 1932. It covers their history to that point!

It is very interesting to read.

Google translation of the ad to the left, with some adjustment:

"Agents assumed at all locations within Dalrne for the 2-cylinder outboard Archimedes 1914 year model. Magneto or battery. The sizes of 2 and 5 hp. Archimedes Company, Stockholm C 41"


The above was from the Swedish paper, Dalpinen, March 1914

 

 

 

Google translation of the ad to the left, with some adjustment:

"The Archimedes is a horizontal engine, with 2 cyl. each for their part time work, moving back and forth . Parts are standard. Perfectly balanced, hence the name "Engine Balance".
The only Balance Engine in the world. No vibrations, no damage to the material of the boat. Reliable, powerful."


Some history -

The following excerpt from Evinrude history explains the general explosion of Scandinavian outboard companies starting in 1912.

I have read that prior to 1912 Carl Alrik Hult had taken a trip to the United States and brought home on his return to Sweden one of the early Evinrudes. In a nutshell, the wooden boat shaking vibration of the single cylinder rowboat motor was unacceptable to the engineer from a country where a great many men made their living from the sea. The fact the fisherman still welcomed the outboards Evinrude exported, and that demand exceeded the supply, prompted the start of many new Swedish companys...with most copying Evinrude's single cylinder.

In comparison, the brothers, C.A. & O.W. Hult, who had an engineering workshop, AB Archimedes, in Sundbyberg, Sweden prospered by solving the problem common to all those single cylinder motors, the horrendous tooth-rattling vibration. The result - in 1912 they constructed the first 2-cylinder outboard in the world. It was an opposed twin, boxer type. This outboard was introduced under the name Balansmotern (Motor Balance) because it ran without vibration. Ole Evinrude, in his "retirement" in 1913 produced a twin as well. The Archimedes BS type was manufactured with little change until the 1950s.


1911 saw Evinrude produce 2000 motors.
"The business was seasonal, however, so Bess contacted several exporters in New York to explore the sale of their outboard motors overseas. At first cast aside, their letter was eventually discovered by Oluf Mikkelsen, a Scandinavian clerk of Melchior, Armstrong, and Dessau, who convinced his boss that the motors had great potential in Norway, Denmark, and Sweden. After a trial order of two motors to be used at a demonstration in Denmark, a firm order for six came—then fifty more.

Mikkelsen and another man were sent to Milwaukee to call on “B. Evinrude” and negotiate a better price for a large order. The men were amazed to discover that they were dealing with a young woman. Bess was more than a match for them; refusing to yield on the price, she received an order for 1000 motors. The problems stemming from the seasonal nature of the business were solved, and Mikkelsen became Evinrude’s New York agent for international sales."

Wikipedia definition:

The boxer engine ( a twin) is a type of flat engine in which each of a pair of opposing cylinders is on a separate crank throw, offset at 180° to its partner, so both cylinders of the pair reach top dead centre together.
Any boxer therefore is inherently balanced as far as the momentum of the pistons is concerned.

Here is the original text, followed by the Google translation.
Ett exempel på Erik Lidwalls uppfinningar och expriment från den tiden han arbetade på DFF. En tidig Archemedis utombordsmotor skulle driva ett varpspel och samtidigt kunna användas i en liten flottningsbåt. Denna uppfinning tillverkades bara i ett exemplar och blev föga framgångsrik men förevigades på detta foto från Tony Nordensjös samling.
"An example of Erik Lidwall's inventions and experiments from the time he worked at DFF. An early Archemedi's outboard engine would drive a warp game and at the same time be able to be used in a small floating boat. This invention was made only in one copy and was not very successful but was immortalized in this photo from Tony Nordensjö's collection."
