Welcome to the new Wizard Outboard Forum.
Here is a .pdf file link to the owner's manual for the Mercury KG-7. The KG-7 is comparable to the Wizard WG-7 and the WG-7A. https://web.archive.org/web/20110518211711/http://antiqueoutboardmotor.info/Garage/KG-7_Manual/images/Kiekhaefer%20Mercury%20KG-7%20Super%2010%20Hurricane.pdf I hope this helps someone.
