Your second post provided more info, especially the link. I could not find any data about skyvision dish, but most likely this dish, as an offset dish, has L/D ratio higher, probably 0.6, and by this, the LNB bar is longer, enabling achieving 2 degree LNB spacing. Your dish focal length is 682 mm (F/D = 0.38) and probably does not allow to receive from 2 degree spaced sats, for example 97 and 99.
Thus, motorizing seems most feasible.
The size of your dish is huge, as for Ku, and LNBF will "see" only central part of this dish, but it is OK, since the outer edges would prevent the radiation from "warmer" Earth to contaminate the signal with thermal noise. So some posters say.
