I was out on the water on the fourth of july and my ski was tied up to a break wall and was banging pretty hard. I rode it back in and it was completely fine. When I got in i notice that the fin of the OPAS on the right side was gone. I was wondering if someone could tell me if i should replace it, or take the other one off. THere are no holes where the fin was and all the parts are still there but the fin. If someone could help me out that would be great. Thanks!
