its easy to fix the jerk situation whenever they come in front of ya and cut u off or get so close they about hit ya.... just idle up beside them real close.... while u are doing this trip your motor up till its barely in the water and turn away from there boat real sharp and i mean pour the coal to it..... and watch as about 200 gallons of water cover them..... then trim the motor down and blast off..... i havent never done this but if someone done what dave said happend to him i would oblige them by gettin them soakin wet.....
