This fin is on Backorder from the manufacturer and will be for a while.
Hobie has identified an Alternative Fin that is a direct replacement. The ONLY difference is the wording on the fin. We will be shipping the alternative fin until Hobie resumes production of the other fun.
Below is the warning from the manufacturer.
An alternative Turbo Fin (Part No. 80151135) is available that can be used to retrofit the older version of Mirage Drive 180s that does NOT possess the “kick-up” function; While this Turbo fin, which is currently in use on the Mirage Drive 360, is compatible with the NON-Kick-Up Mirage Drive 180, the fin is labeled with “Kick-Up” graphics. Please note that the kickup function is solely determined by the version of Mirage Drive on your kayak and not the graphics on the Fin. If you install the alternative “KICK UP TURBO” labeled Fin on a NON-Kick-Up drive, then it will NOT “Kick-Up”, as you should not expect it to.
