Jeanneau 49DS stern tube displacement

I had my Jeanneau 49DS lifted and work done to it. That work included sandblasting of the hull.

On the boat being splashed, the engine, when first put into gear, immediately ground to a halt. It then easily restarted but it was initially hard to engage forward or reverse. That resolved.

However, on the boat being inspected a few minutes later in the water, the whole stern tube had rotated and moved aft. Ripping out the water cooling feed. Time run >10 minutes.

Prior to splash the Volvo stern gland was burped but not re-greased. There was no indication of any trouble with the tube or gland prior to be boat being lifted at the yard.

The boat has had to be lifted again. The attached photo shows the external damage.

Question: What is your view as to the reason for the damage being caused? I would be more than interested. As well as grateful.
