Installed GSA tabs and controller on my 2006 Tige 20v. I used the spacer and made the same contour as the transom to make the hinge lay flat. I also moved the hinge over 1” in the extra hole and relocated the actuator mount on the tab over and drilled 2 new holes. This gave me the the ability to install the upper actuator mount on a flat surface.
the installation took a total of 8hrs and my adhesive is slow cure so I’m now waiting 7 days to take it out for testing.
