Well heres something I picked up last night. Its a Satoh Elk s550g... I think its around a 1974. It has a 1L liquid cooled Mazda 4 cylinder engine. Runs like a treat, all 19.5HP of it through a high/low 3 speed. 6 speeds forward and 2 reverse. New paint is definitely in order, red and cream are the original colors I do believe. I'll have to do some research.
