Urgent need of help concerning my fins

[Wakeboardingmaniac]

I,ve got 1.6 inches mako fins on a jobe sports wakeboard. I noticed that one of my fins was loose so i tightened it and then i noticed that all my fins could move about a milimeter back and forth. Should I tighten them so that they cannot move at all or is this gona wreck my board becase of the pressure? For now theyre lose because i didnt want to break something. Plz aqnswer fast it really is urgent because I can't wakeboard until this is solved.
It's a luck a storm is coming and that I can't do any because it would've upset me not to be able to do any wakeboard for the day!
Thanks in advance!
P.S. they dont move from the top to the tail they move from TS to HS (just saying the orientation of the movement)

I would try to tighten it. I would be suprised if it caused damage. If you are still concerned try to find some rubber washers to use.
