I have a 2000 mercury 20hp 2 stroke it has compression it has fuel but no spark, it ran with a sluggish (sounded like one cylinder was firing) so I replaced the plugs and one plug wire was broken so I put a new wire on too and it ran like a scalded dog for about 1 hr went back to the boat ramp and had my buddy get the trailer and it stalled about 4 times but kept turning back on. Got back to the house and it turned on and cut off before I could wash it out now there's no spark at all?
