CONTINUOUSWAVE

I checked the output voltage while it was running on ear muffs in the yard and the old voltage regulator is working fine. It outputs a steady 14.0 volts at idle and 14.2 volts at 3000 rpms. I now know more about an outboard ignition system than I ever wanted to know., but knowledge is a Good Thing. ...

UPDATE on loss of spark in the 1996 Mercury115 2+2 engine: I purchased a spark checker, a remote starter switch and a DVA for troubleshooting purposes. After watching many videos on how to check the stator and trigger resistances and voltages, I checked mine and everything checked fine but [the 1996...

[Clarifies that the engine that is the topic of this thread is a] 1996 Mercury 115-HP two-stroke-power-cycle engine with an in-line four-cylinder block in which only the top two cylinders operated below about 2,000-RPM. This engine is known as the 2+2 design.

My 1996 MERCURY 115-HP engine [later clarified to be a four-cylinder in-line engine in which only two of the four cylinders operate at low speeds, a design known as the 2+2 engine] suddenly shuts off at less than 2000 rpm. It doesn't spit and sputter. It dies suddenly as if it was switched off. Most...
