I have a 1993 evinrude 225 sometimes when I take off the motor dies. It acts like it's running out of fuel. It will either just die or shutter like it's runnning on 4 cylinders. Yesterday I was on the water, went to take off and only turned up to 3 thousand at full throttle. It never would go on plane. Finally after trying a couple times it did. I have replaced most of the electrical system. The carbs have been rebuilt. A compression and leak down check has been down. VRO Pump?
