Has anyone else had issues with Dynamite failsafes? I seem to run into issues with them regularly. I've had them shut the motor down the minute they hit the water. Not even far enough to move away from the dock. It will run all day long on shore (if it could). Remove the failsafe, and the boat will run all day, with no apparent glitches in communication. I've noticed that they are all starting to get flakey on me. I always check for water in the radio box, and all the boxes I have, have been dry.
