I have a Mercury 150hp V6 motor. When I take it out and you open the throttle up the boat will start to plain at about 2000 rpm's sometimes it will spit and spuuter and slowly plain off, once it is on plain it will take on off. Other times it will just spit and sputter at about 2000 rpm's and will not plain off. When it does this it sounds like the motor is bogging down really bad. When I shift back to idle sometimes motor will just die. It seems to be idling rough. I have just replaced stator (CDI stator). I have pumped all the gas out of the tank and refueled with new gas,replaced fuel water seperator (old one was full of water),replaced all fuel lines going to motor and the fuel bulb. I am stumped, I dont know what else to do. Could it be fuel pump, rectifier, or carburators. Any help will be greatly appreciated.
