Hello, my name is***** you for allowing me to assist you today.
What you have is worn out wear ring in the impeller housing and possibly a damaged impeller. You will need to look from the bottom side of the craft and check the impeller to see if the blades look ok. with a feeler gauge make sure that the clearance between the impeller and the ring are not more than 0.040"
