Everything is back together. No leakage at all now. No vibration at all. So far so good. I left it in the water on the dock. Still makes me nervous that its going to sink. lol. I could do a full write up if anyone needs help with changing this part out. The scariest part was jacking my boat up from the back end to remove the rudder. I only had a floor jack. Wish I had 2 stands to jack it up from the hooks in the back but I had to go with what I had.
