P.S. The 41B197 rewind spring was used on many OMC outboards. It was used in Johnsons as 41-197. When OMC digitized there parts inventory in the late 1950s, most numbers containing letters or dashes were changed to a six digit part number. It was so popular that it became the first rewind .spring duplicated by Sierra Marine. When BMP took over OMC’ they added a preceding zero to the OMC numbers to separate them from their own motor parts inventory.
