Post subject:  Miirage drive GT sprocket quality control issue?
When I was in the states last year I bought the bits to upgrade my drive to GT, but as I moved country to a new job, I didnt get around to fitting them until now. While mounting the two sprockets, I noticed that one didn't seem to rotate on the shaft as easily as the other, so I took the rollers out to see why. Much to my surprise there was a "bump" on the inside of the sprocket tube where the rollers sit. The bump corresponds to where one of the two screws holding on the cowling goes. You can see the bump in the photo below

Will Hobie replace this defective component for me free of charge? I could pick it up from Auckland New Zealand when I'm over there in a couple of weeks time

Yes, something we know about. Caused a clicking sound in some drives.

Many thanks Matt! I'll let 'The Water Shed', your dealer in Auckland, know

Kind of feel like I am quality control duty lately with my 2016 Pro Angler 14...with a stuck skeg, squeaky seat and clicking mirage drive.

Matt - was this issue resolved before the 2016 model year? I am definitely hearing a pronounced clicking coming from my Mirage Drive when peddling. Have heard if from the my very first week on the water. Almost like a metronome...speeds up and slows down depending on my cadence. Wondering if I might be experiencing the same issue. Is there a fix or part replacement recommended? I did not see a response other than 'Hobie is aware' of the issue.

I am not sure of the timing, but seems it was noted this last year. As I understand it, it was one of several tools that had an issue, so very random. You should be able to feel it if you rotate the sprocket by hand on the shaft.

I could not see the bump on the sprocket...grease is in the way of clear visibility. But when I was straightening a shaft last night, I played around trying to figure out if this was the issue. The sound is definitely coming from the rear sprocket on the drive. Thinking that this may be the problem part, but really don't want to tear the drive down unless I am having to replace a chain or something else. Thinking I will just live with it. I already have a set of spare sprockets (and just about everything else), and after inspecting the spares, they look good...so if/when i have to replace something substantial, I will replace that back sprocket, and my guess is the clicking will go away.
