" I have an '89 4.3 Mercru
" I have an '89 4.3 Mercruiser w/ thunderbolt IV ignition system. The engine (intermittently) will not kill when key is turned off. The switch checked good but was replaced anyway due to the intermittent nature of the problem. The engine eventually shuts itself off several minutes later if left running. Normally, I pull the plug on the wiring when I experience the problem. Any ideas ??? HELP... "
