    Are there any markings on the key(s) that you have? Any markings on the switch that might indicate the manufacturer? An old time locksmith might be able to help.

    Take a look at this: http://www.ahlstrandmarine.com/products … -keys.html

    What they are calling "Mercury old series" look like a form of double cut key to me.
