The Interrupter will come off center whenever the input cable/shaft from the throttle and the output cable to the drive do not follow each other.
Getting into gear is normally not a problem because the dogs in the clutch want to grab each other.
When trying to get out of gear and back into neutral the opposite is true, and the clutch dogs do not want to let go.
The input shaft moves but the output shaft does not follow.
Once the forces get high enough, the interrupter kills the ignition, the prop unloads, the clutch disengages and the output shaft releases.
An instant later, the ignition re-energizes, and all that is felt is a slight hesitation in the motor.
All this happens in less than one revolution of the engine and is usually not even noticed unless you anticipate it.
The interrupter will normally only function while the propeller is under a load while pushing the boat through the water.
It will not function when reducing the throttle from speed and going directly into neutral, or while on the muffs on a trailer with the prop not in the water.
If it is stalling going INTO gear, the output shaft is binding. Water in the drive housing is the usual culprit.
Disconnect the Output shaft and move it back and forth
If it will not move smoothly with light finger pressure, a new shaft it in your future.
Once you experience effort it takes to get to the far end; The low cost of the shaft does not warrant trying to clean up the old one.
Do it right, and you'll only need to do it once!
