Re: [OMC-Boats] adjust screw on top of shifter?

Yup, I didn't realize it tell I read it with my own eyes. It's just
another example of why it pays to RTFM. I cross-referenced and the
Seloc manual mentions it as well, but in a slightly more confusing
manor than the factory OMC manual.
And OBTW, the 1969 OMC/Evinrude/Johnson manual doesn't mention the 5-
wire units. But 1970 and newer does.

Remember this applies to only the 5-wire Johnson & OMC controls. E-
rude PUSH-BUTTON owners can ignore. Your "LOCK-OUT" failure typically
allows you to start the engine, you just can't shift. (Covered in a
prior posting.)

My ski lessons got rained out today at Jordanelle Reservoir, near Park
City. 46 F and 3-ft white caps at 08:15 AM. Never got of the trailer.
Oh, well.
