My boat motor starts fine and when you are taking off and put the throttle down then the boats starts missing, it runs almost OK at around half speed then all of a sudden you can hear the motor pick up speed and start catching up to its RPMs. If you try to speed up some more than it cuts out,

Last few times when I loaded the boat I would turn off the key and the boat would still be running, I would hit the kill switch and the boat would still be running. I would than have to throttle down all the way and pull back on the throttle very fast to get it to shut down.
