I am cruising in the Caribbean and just happened to be in a location
with Internet access. I only expect to have Internet until Saturday
noon, so if anyone can provide help in this period, I would be very
appreciative.

I have a 15 HP Yamaha Enduro 2 stroke outboard which is about 5 years
old. It's always run like a champ. Today when I went to start it, it
wouldn't even begin to start. I'm not well versed in the terminology
of outboards, so please bear with me. I am a good trouble shooter.

There's plenty of fuel available at the carburetor.

I don't see any spark at the plugs.

The cut-off switch appears to be working fine. It's open when the
"key" in installed and closed when pulled.

I believe that the power source for the plugs is called a stator and a
rotator. There are 2 wires coming from the stator assembly, but I
don't see any voltage coming from them. I've tried jumping them to
ground and I see no spark. The sealed unit that they lead to is
labeled "63 V", so I'm assuming that the input is 63V and that I
should be able to see a spark from it. I also assume that it bumps
the voltage to a much higher level for the plugs. I've checked the
output of the sealed unit (which leads to the plugs and see no spark.

There's a magnetic switch located next to the fly wheel which closes
briefly on every 1/2 rotation of the flywheel. This appears to
control the timing of the spark and seems to be working fine.

I was leery of taking the flywheel off to expose the stator/rotator as
I don't know how it's assembled and/or what parts might drop off and
how it needs to be aligned. I'm assuming that this is where the
problem is. Any suggestions as to how to proceed and what I need to
be aware of would be greatly appreciated.

The only thing I can think of, and it happened to me once in the bay and
once in Mexico, was that although the cut-off switch appears to be working,
it may not be. The fix for me was to try several times, then jam something
between the key and the switch post. Started immediately. In Mexico, the
whole key and lanyard went in the water... used whatever I could find to rig
it, but it was a bit finicky until I got it right.
