We have a 06 mobius lsv. When I wake surf I can only wake surf without the rope for 10 seconds or so before I go off the back end. What seems to work the best so far is filling the back ballast tank of the side I am attempting to surf and putting everyone in the boat on that side. We also put the wake plate up. I still can only wake surf for about 10 seconds without rope. Does anyone have any suggestions. Here is a video of it. Ignore the family in the audio yelling lol
