The Evinrude model number 100293R corresponds to an outboard motor manufactured in 1974. Evinrude often uses a specific coding system for their model numbers, where the first two digits typically indicate the year of manufacture. In this case, "29" indicates the motor was produced in 1974.
The Evinrude Sportsman model 4416 07661 is a vintage outboard motor, typically produced in the early 1970s. Evinrude's model numbers often indicate the year of manufacture, and the "4416" suggests it was likely made in 1974. For precise identification, checking the serial number or any accompanying documentation would be helpful.
