" Thanks tonyaus for the info.
" Thanks tonyaus for the info. My 225 Yamaha (1988 Excellg) is a YMIS. I have checked all my sensors and they check good. The throttle position sensor is reading 20/1000/1000 ohms as the book states it should. Still leaning towards fuel starvation. I pulled my fuel line off of the top carb and when spinning it over it has a kinda weak pulse action. I also pulled that line while running the motor (I know) and it's kinda steady but weak looking again. How much pressure or flow should my fuel pumps put out, I know it not much pressure wise. Remember, when I choke it, it gets up and goes again. I have cleaned and checked carbs, plugs, you name it. Runs great as long as I am cruising. Thanks again, Mark "
