Ski Pylon Table Mount

Ski Pylon Mount Install Instructions
I suggest mocking up the ski pylon mount to get the proper height and alignment and drilling one hole to match the pin position making sure the mount is square to the boat transom and parallel to the deck use a tape measure not a level drill your first hole.

Align the table mount to drill the second hole and slide the pin into the initial hole level the table mount and brace it up so it is parallel to the boat (you can do this with a clamp or some electrical tape) then using the open hole in the boat ski pylon tube on the boat drill the second hole. Remove the table mount and run the drill bit through both holes you just made in the mount from one side. Re-install the mount and pass the pin through both holes in the mount and attach the table with the bolts that came with your table.
