Mine does not rotate at all. It appears the notch in the cam should be engaged when rudder is down but mine will not allow the rudder to be latched. It hits the top of the cam. I think it would break if forced.
Sounds like the cam is locked in the “down” position. Get a large flat blade screwdriver and wedge it between the cam and plunger and then use the screwdriver to flip the cam back to the “up” position.
Frozen delrin screw is very common and and lots of discussion on this site about it. Best approach (IMO) is to drill it out with a 5/8” drill bit and then chase the threads with a 3/4” tap (or 3/4” bolt with a couple notches cut in the end) to clean up the threads. Then replace the screw and use a liberal amount of grease on the threads to prevent it from seizing.
