has any one had their stern thruster start and run without the joy stick controls on.
 
YES. Just got our boat back from Cap Sante Marine. They have a skinny guy that gets stuck on these projects. 5 hours to get the thruster out. Needed a relay, black box. Total, over $1,700.00 . Works like new.
 
Ours is in the shop right now for the same thing, haven't gotten the bill yet.

This just happened to us yesterday. I assumed it was the joysticks and I was going to change them. Could it be more than that?

Yes it can be something else. Before you start changing parts troubleshoot to determine what is wrong. Have you priced out the joystick? You are talking about $500 and more. That would be the last thing I would want to change even though it may be the easiest.
 
Can’t the cockpit seat and support be removed to gain easy access to the stern thruster? Or does that not make access easier?
 
You can always try switching bow and stern joy sticks to test if it is a joy stick. Odds are pretty good its either a relay or corrosion inside the thruster motor. I am on stern thruster number 3. Water penetration on the first two.
 
I didn’t realize there were issues with the thrusters. I looked in my manual and couldn’t find a maintenance protocol. For those of you who have experience this failure is there anything you can share that might help others prevent or at least delayed failure for awhile?

I am not familiar with the cutwater nuances. On the tugs it is always important to make sure the weep holes on the port stern and side are clear so water can weep out. Use your thrusters sparingly and run them a little regularly. Do not suddenly switch directions or you will surely break the shear pin. Do not use them in bouncing seas because if the bow jumps out of the water and then back in you will break the shear pin on the bow thruster. Occasionally check down by the thruster to make sure water is not coming in, which could indicate a compromise of the seal between hull and exterior thruster leg. Note: The rear thruster has an explosionproof cover, not because of explosion, but to protect it from water. I had my boat for 10 years (R-27) never had to replace a shear pin and only replaced the rear relay once.
 
I had my Ranger Tug 27 (2016) transported to NJ from Baltimore last year. When I launched it, the bilge pump was running off and on and found out the stern thruster seal had come loose during transport and allowed water to seep in at a regular clip. We hauled the boat back out and the seat was resealed to the hull. Launched the boat again and the stern thruster had a mind of its own and was doing its own thing, left, right, stop, start. Would not stop until I shut down the battery. We pulled the stern thruster and sealed a plate over the opening. The stern thruster was sent out to side power who stated there was water intrusion and the circuit board was no good and the unit could not be repaired. I really don't understand like someone else said, its a sealed unit basically and the water leak was a constant dribble into the bilge which was being pumped out every 10 minutes or so. So because of the expense I chose not to replace the stern thruster for now and have just the bow thruster this season.
And also yes, that section under where the stern thruster was has an inch or so of water constantly. Its coming from the rain that runs into the storage area under the rear seat. The drain for the storage has a short hose attached that is aimed at that section but yes I believe the weep hole is not low enough. I chose to point the drain hose toward that section instead of to the starboard side where there is way more stuff. Way more stuff like the Garmin depth finder that wont hold RV antifreeze but that would be for another thread!
