I am going to have a local boat builder flip my boat for me. He has a jig for flipping boats that bolts to the transom using a Porta Bracket bolt pattern. The problem is, I don't have a Porta Bracket yet, so there are no holes in my new transom. I worked with Porta Bracket to develop the below template. It covers four 17" setback models as indicated on the drawing.
I figured I would share in case anyone else has a similar need....
