If you weren't have any radio interference problems. Your motor could have been a little dirty and corroded or even a loose wire could be a culprit. I would open it up and put a light oil on the motor bearings and grease the stuffing tube. As I am not familiar with that particular boat I can't help by telling you how to do it. Other than that if the problem goes away with a little more use then great. If not then it might be time to put in a new motor and prop shaft. good luck

radio interference problems = glitching. I have a few questions. Are you running an AM or FM radio? Did the lunging get worse as the boat got farther away? Did it get worse as RPM's changed? Did it change the longer you ran the boat? Was the motor hot (can you hold onto the motor for longer than 5 seconds)?
