Propeller shaft

Hi there,
Following the latest series of water issues and holes in the keel, I was checking out the propeller shaft and it seems that some type of plastic washer is sliding out from outside the hull towards the propeller.
Should I consider taking out the shaft and changing the washers or is another loose feature on the Albin.
This season is starting to set me back on both time and money while i see the spring approach the west coast of Sweden.
Any help would be much appreciated.
Thanks
James
