The repair manual mentions you have to fit the lower unit and intermediate together very accurately and carefully. Would it be possible to put them together with the outdrive on the boat?"

"If the boat has been sitting for this long time I think You should remove the drive, change the joint bellow and have the shaft splines lubricated!"
