[QUOTE="reedjj, post: 211375, member: 4585"] I have a 2003 yamaha 40hp. The the guy I bought it from said it did the same thing. He said it ran great but if he went to full throttle it would cut out and run slow for a while, then after about a min or so it would pick back up run fine for a few min and do it all over again. I talked to my motor guy about it before I bought it. He said Yamaha 40hp 2 strokes are famous for that and that its usually a fuel delivery problem. He said more than likely the fuel system is sucking air somewhere, or the carbs need cleaned or both. There are a bunch of threads on the net about this problem and many of them have a different solution to it. [/QUOTE]
