Possible bad switchbox. Check for good spark at both plugs.
Will check the spark at the plugs, how do I check the switch? TIA
You are checking it when you check for spark. If you are missing spark at one plug the switchbox will need to be replaced. It can't be repaired.Quote:

Yes it could be a fuel problem but that motor (made by Merc) is notorious for the switchbox causing that.Quote:
