Hi Justin, my name is ***** ***** have access to a marine scan tool such as a Techmate, Diacom, Mercury DDT, or any other scan tool capable of working on Mercruiser engines?

no I do not
Expert:  Jason replied 1 year ago.
There is no way to troubleshoot this ignition system without a scan tool. Did you have any general questions about how the ignition system worked? Or did you want to call it quits?

what type of faults will the scanner reveal? Do you know what issues will cause a no spark condition?
