Re: yamaha steering
so, are you saying with the cable disconnected the wheel spins freely? but the motor is still tight? if so, then it is the swivel bracket that has been either never greased, or greased with the wrong grease, and it has gone all hard, sometimes a gentle heat up with a torch will free it up for a while, but the only permanent fix is to pull it to bits and clean all the white corrosion out and grease with proper marine grease, it is not a hard job, but it is a messy, dirty, heavy job to do.
