    Default Mercury Outboard 50HP Not starting.

    The engine is turning over, all plugs are sparking, plugs are wet with fuel, kill switch is working (shorted it), grounds seem fine (shorted some to check). I don't know how one tests the spark adequacy but I hooked up a voltmeter and saw .3V DC at each plug if that helps; what should one see? Just no igniting, noted by sound and the fact that fuel drips out of leg. The serial number suggests it is a 1984. I am attatching a picture. Could somebody also let me know what the two parts are I point out in the picture? Thanks,Tyler

    #1 is the set of ignition coils #2 is the switchbox. You'd need a peak reading volt-meter to measure the voltage at the plugs. Your problem could be as simple as a faulty starting procedure too. -W

    I have had the engine running for 5 months now, and had no trouble starting it in the past, other than flooding it sometimes. The last while, I experienced it cutting out while running sometimes. Was not sure what was going on there.Normally to start I pressure up the bulb, hold the choke on, and turn the key. Now it no longer works.

    Ok try advancing the throttle a little too. When it cut out while running did it feel like it ran out of gas or someone just threw a switch? You might wanna ohm out the stator as per the manual - just a hunch.-W
