I have a 2000 Yamah F100Y with less than 150 hours on it. It sat for 3 years and I fired up and it ran fine on the lake. Slight miss once in awhile. Changed the in-line fuel filter in the motor and a secondary filter. Ever since doing so it idles great and you can ramp up the RPM's. No problem. Took it out in the sound and you can put it into gear, but when it reaches about 2000rpm it dies. It seems like when it is under a load is when the problem starts. I do have old gas in there topped of with new gas. Didn't have this problem until I changed the fuel filters. Any sugestions would be great... Thanks for your time..
