Our experience was the same: vibration means something is amiss and you need to investigate. Use the comfortable bands of rpm to get where you need to go. Malalignment leads to wear on the Vetus rubber coupling, which then leads to imbalance and further vibration. In alignment it's completely obvious, smooth running over a wide ranges of rpms. Also don’t forget the prop!
