I have a Tohatsu (Mercury) 4 hp fourstroke outboard for sale. Motor is new, used once. Has an integral gas tank with the option to connect a typical outboard gas container. This is a short shaft model (15"). Super smooth and quiet. Bought a larger motor, as this motor was a little to small for my 16 foot boat. These motors list for $.00 (cdn).
