Mercury XRI manual
I would make sure to check the throttle position (TPS) setting, and ignition timing. If spark timing is off, it may run okay when it is not in gear, but once you put it under load it can be an issue. Follow the Timing and synchronization for EFI models procedure in this manual. Good luck (that black blob is the manual pdf)
