OMC ESA not working

It seems the auto-stumbler on my 3.0L isn't working (non Cobra).

To solve a finicky reverse, I searched and found a good thread and link on adjusting the shift cable:

So I did what it says and it seems to be shifting fine. I've got the engine idle really slow anyway so I don't think I'm harming anything, but I go to adjust the shift interrupter:

I haven't yet checked the switches with a multimeter...but looking at the shift control box, the switch on the left (with the plastic, adjustable thangs) doesn't seem to do anything when depressed...if you depress the one on the right it stumbles the engine like I would expect it to.

Is my left switch bad? Do I need to look into something else?

Disconnect the wires and do a continuity test.

Only one of the switches stumbles the engine. The other is an overstroke switch. You won't be able to get the switch to activate when you are on the muffs. Next time you take it out, have someone shift the boat from forward to neutral while you look at it.
