    Pro xs 250

    Anyone else having issue with there Merc pro xs losing prime? Have to pump ball to get to fire in middle of day. Figure this day and age you shouldn't have to do this.

    This is often in the Fuel Primer Bulb.

    So does that mean it needs replaced?

    If it’s going flat there is either air leaking in the system from a leaking connection or cracked fitting, or you have a primer bulb issue.

    Mine did the same thing.
    They Rebuilt the pulse pump and fixed it.
