Need help and advice - new issue with shaft seal

If A is made of fiberglass (correct?) I would expect it is the stern tube, in which B is fitted in and held by the bolt (with the hex) which should retain the shaft seal (B+C) from any movement.
But you have a movement in circumferential direction. Issue, but might not be more and might wait until next haul (winter).

But: Can you move it in axial direction?
If not and leakage is only some drops when moved circumferentially I would monitor it when under way and decide upon observed progress of leakage.
If yes, I would haul now.

B might also be a radial shaft bearing (although pretty short) but wouldn't change my decision.
