Very likely shift actuator is failing, unless there is a a sensor wire shorted to ground for the actuator. You'll want to get this addressed/replaced before operating the engine again.

The actuator was replaced under that bulletin in April of 2019 for the previous owner. That closes the campaign for this serial number.
Since you're no longer under Warranty or Product Protection, it would be your responsibility.

Either can cause this.
Please get this addressed before running it again- it is a potential SAFETY hazard to you, your boat, and those around you.

You're not supposed to attempt shifting unless the engine is RUNNING. Doing so can cause severe damage to shifting linkages and components.
The PCM will normally REFUSE to shift to FWD gear unless there is an RPM signal.
Normally you turn the DRIVESHAFT (clockwise ONLY), not the propeller. Very important the driveshaft not be spun counterclockwise or it can fold impeller blades backwards, resulting in problems or premature failure of the impeller.

Don’s post above, as is so often the case with his posts, reminds me why I do not choose to attempt home repairs on my engine. Despite a long and involved personal history with outboard repair and maintenance, when repairs are required I ask myself “what could go wrong, and how expensive could it be if something does go wrong?” I’ve learned a lot from ace outboard technicians over the years, the most important being that there are still many things I do not know.
