Bought a replacement turbo fin and mast kit for my MD180 drive. Prices are set by Hobie, including the $5 to ship apparently, but the communication regarding my order was excellent. Southwind provided tons of updates and the order arrived quickly.
Perfect. Speeds up your yak.
Use these for my Hobie Outback. Installing them took about 15 minutes. Definitely a speed increase after installing them. When you pedal these things, the kayak really goes. I can barely feel an increase in resistance, I think these are more efficient than the smaller fins. Hobie should just ship their kayaks out with this as a standard.
Worth the upgrade for the speed. The original fins are far too short. If you have used the original ST fins vs the turbo fins you will understand what I mean. Definitely can feel a speed increase with these longer fins.
