Mercury Boat Ignition
Although not boating season, we have been waiting several months for a back-ordered Mercury ignition switch, and it finally arrived. Mercury boat locks that have codes of 123-134 have been a puzzle for a long time. HPC had silhouettes of the keys in an old code book, but the spacings varied from code to code.
The mystery has been solved. Most cuts on the keys aren’t necessary. There are three wafers stacked together in each lock. Each wafer is 0.050 inches thick. “Vee” cuts are used and the 45-degree bevels are wider than 0.050 inches. Cuts overflow into adjacent wafer spaces, so only a small amount of metal is left to lift each tumbler. This is probably the worst lock design we ever have seen. In this case, the mystery is solved, but it’s best to continue obtaining precut keys.
