you can not set up a proper alignment with this mis-alignment, with-out shims, but that will create a hard mount, motor noise thru-out the hull, and when this mount failed it caused an immedient vibration, and noise, obvious vibration continually, what fooled me is it failed after "grabbing air" like you did in the video Rich, I would have suspected the port mount to fail, but when I got to thinking about it, both rear mounts are suspect to the same torgue, when the forward mounts are more subject to a torque issue on the port side.
On the 4 and 6 cylinders, the front mount is more critical, a structural failure there can be corrected by re-aligning ... but just for the present.
