Can anyone help me with a problem with a 1988 80 HP mercury triple. The lower cylinder doesnt spark when starting sometimes. It never fails when running. The other two cylinders never give a problem. Can anyone help? Can anyone tell me what resistance voltage levels should be for the trigger / coil / stator? Is a manual available on line? Oh one other thing when I swap the trigger wires and the HT wires it will start up again as if I am disturbing the wires somehow.<br /><br />Thanks in advance.

Re: Mercury 80 HP no spark

Thanks for that. I suspect a coil is faulty. Are coil failures common on these motors?
