My question is, should I be trying to tap the rod out the port side of the tilt tube, or back in the tilt tube and all the way out? It seems like heat might be necessary.
I have gotten the steering rod to spin freely,
To get the rod out, you're gonna have to pound it out most likely, which will mean pulling the motor off the transom...
Heat it and beat it!. Thats what I had to do when mine got stuck. Heated up the tilt tube with a propane torch and beat on the rod end with a dead blow hammer. You can get the lead shot filled plastic coated ones at Harbor freight pretty cheap. Don't hit it with a steel hammer you'll just mushroom the end of the rod. A brass hammer might work too. You can also protect the end of the rod with a hunk of 3/4" starboard. Also spray the crap out of it with PB blaster and let it soak for a day or two.
