   We have the same Quick BTR 250 and are able to get all the parts from any Quick dealer in Europe. If they don't have in stock, they usually get them in a couple of days. In Spain, the main deal is Pro Nautic a big company that sells only to dealers. I hope this helps.

	This seems to be the best thread to build off for thoroughly diagnosing a thruster problem. Though this thread is oriented to the bow thruster (BTR250 on a 588), my problem pertains to the stern thruster (BTR185 on a 588). Here is what I have been able to diagnose: 1.) Activation from the helm console does cause the thruster to deploy into position. This is a separate 12v circuit from the 24v thruster drive. 2.) I do have 24v+ at the stern battery bank. 3.) The inline fuse has continuity. 4.) I do have 24v+ at the motor starter relay. 5.) When I activate the joystick, the relay "thunks" in each direction suggesting (to me) that everything is ready to go. 6.) No activation of the motor itself. If it spun but without propulsion, I would look at the U-joint that some have reported problems with. Doesn't seem to be my problem. When I was hauled out last summer, I was able to spin the thruster propellers with a load I would expect for it to be coupled to a motor rather than detached. 7.) I open the motor inspection hatch for the brushes. No carbon build-up, commutator looks fairly shiny, and there's no other direct sign of water ingress or corrosion. I did not pull the motor. While I think I understand you can do so while in the water, I was nervous to do so alone. While there's a chance the relay isn't completely performing its job by completing the circuit, I would think that's less likely to be the problem -- especially since neither direction works. I don't know a lot about troubleshooting DC motors, are there ideas about determining which of these is my problem?

	Hi Jon. You need to determine if the motor shaft can spin freely. From what you’ve tested it seems to point to a frozen shaft. This can happen when the thruster housing seal starts to leak. The water has no where to go other than up the motor shaft and past the motor bearing. It doesn’t take much! I filed a weep pathway in the motor flange so any water will leak out and not damage the water. It also serves as a visual indication of how the seal is performing. Pulling the motor is easy. Even if the seal is leaking it will only be drops, not a flood! There is a key and key way on the motor shaft so don’t loose it.

	Thank you, Leon, for the suggestion and the words of encouragement. I won't be back there for a little bit, but I will update this thread with my findings.
