Someone on FB sent the pictures to TPW and they said it was not zebra mussels but some kind of fly or insect eggs. What was weird to me is that they were all under the water line. I had never seen anything like it. I pressure washed them all off and cleaned & flushed the boat because I had no idea wtf it was. They were a little more crunchy then Uncle Bens rice and had a bitter after taste so I knew Kenny's guess wasn't right.
