"I have a 2.3 liter OMC. with a few problems. (BOB knows) how can i TELL IF THE esa IS WORKING. It never has "stumbled" when shifting. If I manually push the button in when it is idleing, it doesnt do anything. Maybe this is what caused my outdrive to fail. I am replacing shift cable this weekend, and putting on a used 2.3 outdrive. (learned my lesson, to not use a 3.0 on a 2.3 motor)"

"I'm no expert, Bob is the man when it comes to these. It sounds like you are on the right track. Pushing the microswitch on the cam (white arrow in picture) should activate the ESA and stumble the motor. The other switch (black arrow) should turn the ESA off. Mine quit working too. I do not have any problems with going in and out of gear but would feel more comfortable with it working. Just make sure your idle RPM is low. I'm not sure what the four cylinder specs are. I have the V8 and try to keep it around 500RPM. I know you can still buy the ESA.

Not sure what year you have or if you have the mechanical shift, but here is a link that talks about how to set the switches.

I should add that this set-up is on the OMC STRINGER model and not the COBRA. I'm not sure if the COBRA system is similar.

"Kevin, If the engine doesn't stumble when you activate the shift interupt switch (it's the switch with the arm and roller on it) the first thing I would do is test the switch. Unplug the connector to the switch and use an OHM meter to see if the switch is actually opening and closing. If the switch tests good your problem is possibly the ESA, the overstroke switch, or a bad connection or broken wire. First try to determine if you have the old or new style ESA. Look at the connector plug to the switches. If there is a jumper wire on the ESA side of the plug (just a loop out of and into the plug)then you have the old style and need to check the overstroke switch to make sure it is not stuck closed. If both switches are good then check all the connectors and wiring. Mine had a broken wire (broken inside insulation) at the plug between the ESA and coil. Use your meter to check continuity through all the wires.
If everything checks out, your problem is likely the ESA.
Hope this helps till Bob checks in. The guy is sharp!"

Correction-
The overstroke switch is "normally closed" so you would need to check it for "stuck open"
