Thrust Systems stern thruster
I have what I believe is a ThrustSystems ST-360 stern thruster. The company was based in Sarasota Fl. at one time but I am sure that was quite a few years ago. The starboard prop on the thruster is stuck and will not turn by hand or power. I hear a clicking sound when I push the button for the starboard thrust. The port prop works fine and spins by hand. This is the only owner's manual that was not on the boat when I bought it four years ago.
I am looking for help with an owner's manual or what the problem might be.
