If you are running the 8″ slide master manual jack plate…which I am pretty sure you are, you will need the 9″ set back on the side mount. That is the same that I ran before I went to a hyd plate.I am running a Puma FTD but I dont think there is much difference at the transom between the Erya and Puma. There was no way I could have run a 6″ setback. Jamey http://images.yuku.com/im…6c27aea485688b09ac_t.JPG Im on my iPad so I cant post pic but here is a link…think this should work.
