Jack Craib's Rowboat Motor Information Site Joymotor Joy Engineering Company |
The earliest mention of the Joy Engineering Company that I found was from December 1914, in a list of newly incorporated firms. In spite of being manufactured until 1921 there are few around. The motors evolved over the years. For details on construction and changes, plus more photos, refer to Arlan Carter's book The American Rowboat Motor. |
