When you're reinstalling the drive you'll know if it needs an alignment or not. Line the u-joint shaft straight into the gimbal bearing & push the drive straight forward. If it fights you & you can't send it home then check your alignment. You may need a screwdriver to rotate the u-joint shaft in case it binds on you. Don't forget to grease the splines on your drivevshaft, you don't want to run that dry. I used spline grease, if you don't have any on hand any Merc dealer should have it in stock.I found some paperwork on my boat and a receipt for repairs that changed the bellows and bearing 2 years ago? and in boat years for my boat 2.6 hours ago according to the receipt and my hour meter!
Im not really worried about that but as I was doing some research about using the alignment tool, I am curious if I only changed the shift cable and not remove anything else would I even need to realign the motor?
what could of moved or caused anything to need to be realigned? or is this something that should be done when realigning the out drive?
