dear romanr99 it is better to haul out
i fixed one boat 10 days ago with the same problem a jeanneau
but it is different type of strut.check also your earth cable that is connected on the strut normally it is connected on the srut and going on to the engine
if you find loose screws better replace silicone that has or epoxy
putty whatever they have put on your boat so you know you are 100% sealed and secured .
The only thing you must pay attention is the movement of your shaft when you tight the bolts check by your hand the shaft that rotates freely so you are sure the strut is at the same height and nothing changed.Of course change your cutlass bearing with new and then check it :-)
