Hi All, Picked up this gem at auction. Other than it being made by SBM in Sweden, I can’t find any real info or specs on this specimen . Does anyone know anything about this outboard? Please share. I have never seen one like this so I thought it would for the collection. Maybe I’ll fluid film it, wrap it tight in plastic and put it in a 10 foot hole. Maybe some one or thing will find it in a million years. I’ll put a note with it saying “you figure it out”. Wish our 2 team Mates in Sweden had Email addresses. Anyhow , Take a look at the pics and share what you think. Thanks, Matt.
Hi !
George Emanuel sent me an Email about your motor.
Your motor is a Swedish motor made at the SBM factories in Uppsala, Sweden.
It is Model 3,9 and Type 031 (the first numbers in the #number).
It was sold under labels Archimedes, Volvo Penta, Crescent and Monark.
Your motor is missing the cowling so what is was sold as is hard to say.
Depending of the picture on the carburetor (8/15,5/170) I can say it is produced in 1974.
Hoping this helps a little.
