Hi, I have a 75 hp with the same problem .won't run above 2500 rpm,, I cant find the swith you show in this great video.. Do you know if it could be placed in the handle-bar assembly at the controll-panel ? Regards Paal
Checked this one I unplugged it and it work so I said it’s the switch but I replaced it and it was still doing it won’t rev up then I took it back off kept the wires plugged but not installed and it’s working again. Need help seems to be working without it installed with the wires connected. What else could it be?
Check that the switch still operates smoothly by hand after it’s installed. If the screws are too tight or some kind of imperfection in the mounting surface may jam up the new switch.
It should be attached to the bracket the shift cable slides in. Looking at an old parts diagram it appears that the wires that connect it to the main wire harness may use bullet connections instead of a single plug. They can be hard to see, if you can find the wire they will lead you to it. There is always a chance someone removed an and just connected the wires together. Hope this helps you out. Good luck
un grand merci depuis la France 😊
Just to end my own question, I got the answer from a dealer in Norway. On smaller engines, the switch is located under the separate oil tank. :)

It’s not the issue. I end up taking it to the shop. Hopefully it’s an easy fix will update
What diagnostic system are you using?
I’m using the Mercury g3 software.
where is the shift switch on a 2008 mercury optimax 115
