Thank you for that information. One of the reasons is because I have a ticking noise while in neutral. When I put it in drive, the noise goes away. I had a marine mechanic remove and service the outdrive and he indicated everything was okay, however it came back. Then when it was winterized they indicated that they heard the tick and felt it was a gimball bearing. I also feel a slight vibration while on plane and making a hard turn. So in all of my research, I think I should replace the gimball bearing and u-joints. Does anyone else have a suggestion?
