It would probably cost more money to have the lawyers draw up a cease and desist letter than they would recover from individuals who just added some trim tas to the sides of their boats for their own use.
If they added the actual surfgate system to past and current wake boats for a profit, then yes. A DYI'er adding aftermarket trim tabs to their own boat, No. You can buy those trim tabs and have any local shop install them or do it yourself. How you mount them is up to you, and in no way a patent infringement.
