I have a 2020 Tandem Island with the new MD180 drives with kick up fins. The problem is that the drive fins kick up by themselves under a stiff wind (sailing fast). They will not lock back into place by pedaling them (like Hobie advertises). The force of the water going by them is too great. I have to physically remove them from the well and snap the fins back in place by hand. I have tried to adjust the set screw so that it takes more force to kick up the fins but when I adjust it in enough to prevent false kick ups, when I do actually hit the bottom and they legitimately kick up, I can’t get them to snap back into place (even by removing the drives and snapping them by hand). I have contacted the dealer and requested the older MD180 drives as a replacement. I feel, after a few months of sailing with these that the kick up fins are not practical on the Island boats. BTW I already tried having one drive replaced, thinking it might be a defective part but the new had the same problem. Has anyone had any similar experiences? This has been a real issue for me since getting the boat new in March. I appreciate any insight.
