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

The question you had on your JOHNSON/OMC single-lever remote control:

I had an opportunity to grab a OMC factory manual from 1969-1970. The
screw (recessed and on top?) is used to adjust the interaction of the
FAST-IDLE/(START) lever with the N/S (neutral-safety) cutout.

In other words, it is possible to (mis) adjust this so that one could
never start, even a warm boat with the main THROTTLE lever in NEUTRAL,
without first advancing or partially advancing the FAST-IDLE/(START)

Does that make sense?

BTW mine is adjusted, so that I can always do a hot start in NEUTRAL
without advancing the FAST-IDLE/(START) lever.

If yours was mis-adjusted it might explain why you were encountering a
locked-out staring condition.

Did you see the link I posted to the $200 new replacement switch?
