I have a 2001 Merc 115 4 stroke EFI outboard that is on a 19 ft Alumaweld. Purchased new last July, 2001 in Portland, OR. Max RPM is typically 5100. Went to Montana which is at least a couple thousand feet higher in elevation. The motor would not exceed 4300 rpm at WOT and was very sluggish as if it was choking out. This lasted throughout the trip. I assumed it was due to the higher elevation? On the other hand, I thought the Merc 115 was self adjusting on fuel/air ratio? When we returned to the lower elevation, the motor again ran fine at 5000 rpm. Anyone know about the self-adjusting asumption on this motor?
