C.E. Scott and H.B. Atwater owned a small tool making and punch press operation. They were approached and agreed to make an outboard motor, which became Champion. Then they began making Firestone and later put their own names on the motors that became Scott Atwater. They sold out to McCloch and the name on the outboards eventually became Scott and Scott-McCulloch. By 1964 all of the motors were changed to McCulloch.
