I have always had Berkley or Dominator pumps, and none of my boats ever had the problem my wife's Carrera is having.
She has an American Turbine. When we first put the boat in the water,  it's gets an air bubble in the pump and won't grab water. Sunday it took a few minutes with the boat running before it burped and then started flowing. 

Why does this happen?

What can I do to prevent or speed up the process?

Is this an indication of something being wrong?

Thanks, Jeff
