Has anyone had problems with their stern thruster just coming on while boat is in harbor? It started to just come on with multi second burst. The joy stick control is off as is the remote control. Just started doing this. Did it 4 or 5 different times during the day????
 
Could be condensation on the control boards in the housing.
 
Do you mean on the joy sticks or thrusters. Everything in the cabin is dry. Thanks for your help!!
No, the thruster. I had the same thing happen to me with my forward thruster. I called the manufacturer and they said condensation on the board could cause the thruster to activate. We had just had a rapid temp change on a cruise to FL. Warm water then rapid air temp drop from a cold front. For the next month or so, I made sure to turn off the thruster switches at the PDP as a precaution. After a couple of months, I started leaving the switches on. Never happened again.
 
Thanks Bob mines an 2010 R29. It has been goofy weather here in AK.
