I had a Mercury 6 hp engine from 1963. Black and chrome made in Wisconsin, not Japan. Two cylinders. You could put a glass of wine on the top it would just sit there. One pull. Quiet. Wish I still had it. A mechanic tried to buy it off me.
Now i have a four stroke Tohatsu 6 hp motor. One cylinder. Starts easily. Loud and vibrates. But very stingy on fuel. and dependable.
