yamaha 150 will not rev over 2100 rpm

[ssfoxrunner]

I have a Yamaha 150 2 stroke that will not rev over 2100 while in gear. It looks to be leaking gear oil also. How do you know if the foot is bad?

Can you provide a little more info? What happens when you try to rev? Does it sound normal? Do you have engine alarms for water temp and oil? I know that my Yamaha's will throttle down if they run hot and/or sense water in the system. Please provide as much detail as you can.

I don't have any alarms sounding. The engine runs fine at low speeds. When I run up to the 2100rpm range the motor seems to drown out, so to speak. I have been told that it could be carbs or the stator.
