Re: What RPM Should I be at when idling?
We have a 1985 120 And finally solved the hard shift issue. Would not easily come back to neutral from either foward or reverse. Cable seemed aok. There are other posts explaining this, probably better. Those helped me fix my issue.
This is not something you can do on the trailer. It has to be in the water. Carefully watch the interupt switch plate assm where the cables are. Have someone put it in foward/reverse and back to neutral. My plate would move only when coming from gear toward neutral (due to the gear dog pressure), however the "high" spots on the bracket that correspond to foward and reverse did not make the switch. In gear in normal operation the switch arm sits in the lower U or V portion of the plate.
As you are shifting from gear to neutral, making that switch very momentarily kills the engine, which drops RPM's enough that it helps release the gear dogs, thus it easily slides back into Neutral.
In my case, everything was aok, except I had to slightly bend the switch actuator arm so when it was at either high spot the metal arm would protrude out enough to make the switch.
It was like night and day afterward!!! The interupt switch working makes a HUGE difference. It was dangerous constantly fighting that, expecially in close quarters and trailering situations.
