Is it a folding prop? A non-geared folding prop will occasionally fail to flip both blades open, resulting in unbelievably violent 'vibration' as a horribly unbalanced (single blade, effectively) prop turns. Usually coming out of gear and re engaging fixes it. This is probably the only way a strong vibration like that could 'come and go'.

On one of our previous boats we got into the habit of a quick burst in reverse prior to engaging forward gear; that usually prevented this occurrence.

I doubt very much it had anything to do with your gland adjustment.
