I have a 1987 3.0 Liter Alpha1 outdrive that shifts, tilts and operates perfectly, no strange noises etc. I have had it for 12 years. I have noticed that the starboard side of the outdrive contacts the long tab that sticks out of the rear of the gimbal ring. The port side has about an 1/8" gap between the outdrive and the gimbal ring tab. I have greased all the pivot points monthly since I owned it. I do not feel any play in any of the pivot points. I never hit anything with the outdrive. The starboard side of the outdrive now has slight scuffing from making contact with the gimbal ring tab. It looks like a worn hinge pin could make the bell housing and outdrive sag to one side, however I feel no play in them when I lift and rock the outdrive. Any ideas??
