Nautil problem....need advice

[TBone]

My 7500 PGV has been acting up recently and I noticed it even more this past weekend. When I got into a few fish and set the hook on the take the spool would kind jump or skip with the weight of the fish, not like a normal drag working. Kind of felt like the spool would slip the opposite direction when I was reeling in. I'm thinking a worn or busted gear...not 100% on it though. The reel is a little than a year old and has seen a good amount time in the surf, but I keep up on the maintenance as best I can. Any help or advice would be much appreciated. Thanks a lot guys.
