You can break or wear out just about everything or anything on your mirage drive.

here are some of the common things that tend to break:

Idler cables
Drive cables
Masts
Idler wheels

These items do not break as much:
Crank arms (like that other guy said) I haven't had one break and splines


it's not common to have some of these items wear out:
Drum shafts
Spline shafts
Drums



Here are some helpful tips on preventing things from breaking?

everything mechanical it will eventually break. Inspection and maintenance will make your mirage drive last longer and of course that will make it more reliable.

In well over 20 years of kayak fishing I have never broken a paddle. :paddleersmilie:

That is why the paddle is a good back up if the mirage drive has problems. It is definitely a back up......maneuvering a kayak with hands free to reel in fish, eat lunch, adjust fishfinder, take photos....etc is why kayakers switch over.

Just replaced linkage on my drive. Will use old parts as backups. Tuned rudder and am ready for the rest of the season. Fastlane service was great. In and out under 1.5 hours. Will take a 7/16th wrench and small vise grips with me from now on 'just in case'. Make sure you have a paddle for back up for those who run pedal systems. With that said, pedal system for fishing is super convenient and imo the 'only way to go'.
