Narrative:

Shortly after departure during the climb phase we experienced a high oil temperature indication [in number 1 engine]. The temperature was approximately 198 degrees and was discovered at 26;000 feet. The thrust lever was retarded with only a marginal decrease in temperature. We decided to level off at 26;000 feet; 2;000 feet below the single engine drift down altitude; and perform the appropriate QRH procedure. The QRH procedures were accomplished by the captain while I flew the aircraft and communicated with both center and tower during the diversion. I performed the single engine visual approach with no problems and an uneventful taxi to the gate.
