This is a direct fin replacement for the Hobie Mirage 360 Kick-Up drive.
This is ALSO a replacement option for the MD180 NON-Kick-Up Drive. Please note adding these fins will NOT convert your MD180 to a kick-up drive. These fins DO HAVE KICK-UP printed on them but will function the same as the fins you are replacing.
From Hobie Cat:
An alternative Turbo Fin (Part No. 80151135) is available that can be used to retrofit the older version Mirage Drives that do 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.
