What kind of motor? It was most likely a OEM switch that failed. I have been having to change too many late model ign. switch`s on Merc 4 stroke outboards. Also seeing some starter problems with late model Mercs. I have not had any problems with Sierra ignition switch`s. "Heck" they are all made in Mexico. When you splice the new switch in, solder and shrink wrap the connections.
