Welcome to the new Wizard Outboard Forum.
I have a wizard 7.5 horsepower outboard boat motor see. No.61700710-4165
The only 7.5HP Wizards were made by McCulloch and Eska.
McCulloch would have MLM-69 at the front of the model number.
Eska would most likely have ESK66 at the front of theirs, except model 1706 & 1708.
