Narrative:

In the vicinity of orf, washington center asked where we were going. I replied to the bacus intersection. He said he did not show that as our flight plan, but that the route we had would be fine. The 3 of us had a conversation in the cockpit and determined the captain had entered the wrong route in the FMC. He elected to continue on the route he had originally entered. Unfortunately this brought us approximately 425 NM off the coast line, well beyond the certified limit. In the vicinity of the bacus intersection, washington center advised us to switch to new york oceanic giving us the HF frequencys. As we had no HF radio we asked for the arinc frequency which they forwarded. Unable to make contact on arinc we tried to call washington back but could not. We then contacted another airline's flight which relayed position reports to new york oceanic until miami center gained radar contact with us in the vicinity of foord intersection in the caribbean. The flight proceeded without incident.
