  • Unusual stall problem

    I have twin2007
    F250 TXR four strokes. Initially they would start and die immediately.
    I replaced the fuel, replace the large 10micron fuel water separator, and both of the engine mounted yamaha fuel filter / water separators on both engines.

    Now the engines will start and run, but they will die after a couple of minutes of running at idle or near full throttle. A couple of squeezes on the primer ball and they start right up and run again. If i hear them start to die, i can squeeze the primer ball and they'll run again for another couple of minutes. Oh. I'm not running on the boat fuel tanks but a 5 gallon gas can of fresh fuel.

    What do you guys think?

    Probably fuel pumps..

    Not keeping the VST full, OR you have a vacuum leak (bad seal at one of the filter seals). Its not pulling fuel into the system, your manually doing it with the primer bulb..
