we are refurbishing a 1985 ski barge, by dilks and co mfg, arkansas. Manufacturer is out of business. We are installing a new console/steering assembly. Do we center it on the midline, or were they offset? Even a picture of one of these would really help. We just want the balance to be the same as when the boat was manufactured. we will use a 75h evinrude o/b, and a 10h evinrude o/b. we are stuck at this point of the project! thank you very much.
