"Ok, can help you a bit here. You have an Elgin outboard, manufactured in Canada (between about 1960 - 63) by West Bend (Barrie, Ontario) and sold at Simpson-Sears (now defunt, previously affiliated with Sears-Roebuck). There is almost no information on these motors out there anywhere - so I can't help you with the horse power. Also, odds are slim that you will find a manual. In the U.S. these motors were made by Scott-McCulloch. If the patents/designs were shared you may be able to find parts. Perhaps if you could post a picture of the motor, someone may be able to help identify the hp for you."
