I have a Yamaha 115 4 stroke 2007, at no load RPM's will go

Customer Question

I have a Yamaha 115 4 stroke 2007, at no load RPM's will go to 6000 plus under a load they will go only to 4700. I have tried to restart and go full throttle and a few times I was able to go to my max under a load to 5200. Why is this. We have cleaned the complete fuel system and tank.

Hello my name is ***** ***** am I speaking with?
I have some questions back to you.
What is the model number on the engine
When was the last time it made full power under a load?
Have you measured fuel pressure with the engine cover off and the boat at maximum speed?
