mercury 1250ss 125 l6 is cutting out just as soon as I advance the throttle and in foward gear, both in water and out. The RPM will increase, but slowly, and then it cuts out. If I rev it up too fast it will just cut off. At first I thought it was the timing, and then I thought it was the carbs, and now I think its the brush and spring inside the cap. So now that I'm really thinking sideways about this I was hoping you could help me. Thanks from me dirty d.

Put a timing light on it,and go on down the line and see if all spark plugs are hitting.Check your plug wires too for arching.
