I recently changed the sparkplugs in my 200 / 2000 Evinrude Fichts, and we changed all the batteries. While We idled at the dock, the port "check engine" light and horn sounded. I immediately turned it off, waited a few minutes and started it back up, and it ran fine. When were idling out to test run it, the nstrboard engined did the same thing, however, after turning it off, and restarting, it would run fine for a few minutes, then sound off and light again.
This sounds like ECU, but did disconnecting and reconnecting the batteries or changing the plugs mess up the ECU?
