Probably the gimbal bearing. Have you tried to grease it? Did it help any?

There is a grease fitting on the starboard side of the outer transom plate that feeds the bearing. It is at about 4 o'clock and close to the transom.

But at the stage you are describing; it and possibly your u-joints are going out.
