Today when I was out fishing , I had to turn the steering wheel hard to Port to avoid a boat ahead of me fighting a Salmon. I was only going trolling speed and when I turned the steering wheel a couple of turns there was a loud metallic sounding spinning noise coming from the helm area. I looked behind the helm expecting to see something broken hanging there but all was intact. The steering seems to work okay other than the strange noise it made.I suspect that this is the original rotary steering system that come with the boat 29 years ago when it was built new. Has this happened to anyone else and does anyone know what this noise could of been . Thanks Tug.
