did I hurt my packing gland? need quick

I looked up the proceture and got nuts mixed up because the manual I looked in didnt have names on them and my boat was way loose and didnt match the drawing so I ended up tightening the packing nut with a wrench until it was tight. I realized the rubber through hull piece was bacically locked to the shaft because of that. I realized my mistake and backed it off all the way then went hand tight with it then set the jam nut.

My questions is did I hurt it or di I need to repack it or can I fix it if I screwed it up? I felt dumb after I did it but I have never had to do this before.

I want able to bottom it out. It still had about 3/4" of threads left. I was just wondering if I back it out, will it be resiliant enough to expand and go back to normal or did I kill it by squishing it? It can be a winter project, but I still have about 2 useful dayse of riding left, today being one of them (I hate minnesota)

I dont want to replace it if I dont have to thats why I wanted to know if I hurt it enough to replace it.

I took it out last night and it didnt seem to leak at all, bilge was really dry. I forgot to feel while we were on the water if it was heating up though. I did back off the nut in hopes of expanding back to normal size anyway and I think it did. I will have to check it out again next time I go out.
