Has anyone ever seen the an engine control set like this? It has one
lever in the cockpit but with something like a center ring with a
short axle stubb sticking out as if it might have also had a second
lever next to it at one time.

sort of sounds like it should be a two-lever system, but it's hard to
say without seeing pictures.

I had a Yanmar 2GM with a single lever control - moving the lever
forward engages forward gear, then advances the throttle (not quite
correct terminology for e diesel, but...). Moving the lever back
engages reverse, then advances the throttle.

There were two cables from the control lever - one to the injection
pump (speed control), and the other to the transmission.

You can easily determine if it is a single or dual lever system, by
moving the existing lever - if it is a single lever control, there
should be a detent at the neutral position, and you (or an observer)
should see both the speed and shift cables move as you move the lever
through neutral. If it is a dual lever system with one lever missing,
only one cable will move, and you won't find the neutral detent if you
just have the throttle. If you just have a shift lever, it should
have three distinct positions, and no variable throttle feel.
