Check to see how much grease it takes in the zurk.. if it pushs water out of one of the seals, then yes you at least have bad seals. but wiggle the prop side to side and see if there is any play in it. if there is any play, then you would need to replace the bearings while you doing the seals. good luck! let us know what you find.
