Need new steering for Yam 150 OB

[batkins761]

My steering is not at the point where I have to strain to hold it, and turning to port is damn hard.<br /><br />I have a Baja Sunsport 186 with a Yamaha ProV 150,<br />both 1988. I would like to get a steering system which will turn easily to both sides.<br /><br />From what I can tell, my options are rotory, rack and pinion, and hydrolic. Rotory and rack and pinion seem to come in single cable and double cable types.<br /><br />I'm a little confused on the difference between rotory and rack and pinion. Does this refer to the mechanism at the helm, or at the motor?<br /><br />What type reduce loads the most? I would rather not spend the money for a hydrolic system, so I am mostly trying to decide between rotory, rank 'n pinion, and single vs. double cable systems.<br /><br />Am I limited by the motor, side if motor well, boat, etc?<br /><br />Thanks!
