You have a steering cable with a rack and pinion helm station. Very likely all shot.
Looks to me like you have all kinds of work to do.
Is the motor locked up?
I've been working on taking the steering apart. It looks like the steering has three tubes.
1. Outer and threaded on both ends, which is stationary. This one moves in and out fine.
2. Middle tube is seized so badly. I was eventually able to get it to move in a bit but now I can't move it out. I have tried going as far as hooking it up to the winch on my truck but I just spun the boat trailer around.
3. Inner tube which is connected to the helm, moves fine. It was dirty and I cleaned/greased it.
The photo shows the part that is stuck, which is where the motor attaches. The motor spins fine on its own.
I'm guessing there's no way to free the stuck middle tube. Anyone know what parts need to be replaced?
