It’s a 2002 mercury 90 2 stroke starts and runs fine but won’t throttle up and go as it should???

It’s like it’s electronically in limp mode

I'd try a cylinder drop test make sure you're running on all cylinders. What happens when you throttle up? Does it stall or run normally with lack of power/rpms?
