TRS equipped Fountain that has vibration that increases with increased drive trim. U-joints replaced 5 hours ago, old u-joint hardly worn at all, just a slight indication of "brinnelling" but not detectable by feel. What other causes could this be? (330 HP, BW Trans) Vibration gone at drive position "2.5" but increases with drive at "0", then progressively worse as trimming out.
