I recently purchased a Penn US113N and us it for bottom fishing. As I was reeling up a small fish it would seem to skip every 7-10 cranks. I thought it was me so I dropped it down again and sure enough it happened again. I put it aside for the rest of the day and used my 20 year old 113H. Over the weekend I took apart the US113 and noticed the part that connects to the spool is rounded and appears to be worn. Could you tell me if it is suppose to look like this?
