The original- This tool is made of durable/ tough resin. This is a timing tool made to fit an Evinrude 6hp Fisherman old school outboard motor. Instead of setting the timing by the point gap (0.20") you can now set the timing in the more exact way. Timing fixture may be black or grey. It will be manufactured from ultra durable (tough resin 2.0) and will last a very long time. Made to fit my motor, but should fit the following just as good: 1951-1976 5, 5.5 and 6 hp motors 1951-1958 7.5 hp motors 1964-1973 9.5 hp motors 1951-1963 10 hp motors 1951 and up 12 hp Gale motors 1951 14 hp motor 1951-1972 15, 18, 20, 25 hp motors 1973-1976 18, 20, 25 hp motors: Timing Set Video: https://www.youtube.com/watch?v=eNK2TEeQQv0
