I wouldn't buy one. It is a lawnmower engine that they are trying to adapt to small outboard. Low rpm motor, loud, and not sure how much tilting the oil in crankcase can take for shallow water running. Find a "real" outboard.
The guy who was looking at it has the Mother in law of of the century. She bought him a brand new Tohatsu 5 HP outboard today, been out in his canoe and outriggers testing it out. I did not like the Briggs myself.
