Hi All,

I went out the other day in my Tandem Island and noticed one of my Mirage drives wasn't pedalling correctly.
I could partial pedal only and pulling it out, the fins were offset 20-30 deg from alignment.

I unbolted the the drive chain and noticed the sprocket teeth were worn away right under the fin.... It was the forward sprocket on the drive.
Inspected the other sprocket and other drive - no problems.

i bought the TI in June 12 and have only 50 hours on it (only used it 6 hrs this summer so far)
I had not pedalled into a rock with the damaged drive, used only in freshwater lake on a trailer and boat ramp SOOOO
How did this happen? I have looked at the Mirage Maintenance info on this forum and kept the cable tension adjusted, also lubed and anchor it in lake instead
of pulling up onto sandy beach.

I read that the middle cog on sprocket is enlarged to lock on chain, if this wasn't done, does it self destruct?
I called dealer and txtd foto but have not heard back yet.... Is this a warranty issue?? Thanks :?:

Could be warranty, but most likely damaged when on a concrete surface / ramp or rock. We just don't see teeth fail for many other reasons. That would be unusual. If drives are in the boat and the boat is on dry land...

Follow up with your dealer. Photos and serial number is required for a warranty claim.

A new replacement sprocket cost $17.99 - not a major, and very easy to install as well.

To All,

I had read the mirage drive repair info on our forum. I am 6'4" 240 and my son is 6'6' and 250 so if we are pushing hard on the drive, can we strip it?

It would seem to me that the sprocket teeth top dead center-under the fin would have the most strain on them for each pedal stroke because the least amount of
teeth are carrying the load. If the chain slips off the sprocket it will be shaving the plastic off the cogs - can we put locktite on the chain?

Thank All

It would be very unusual for the sprockets to fail under pedaling loads. Likely the chain was loose, off the centering cog or damaged in another way.

Loc Tite where on the chain?
