In my 88 Baja running at higher rpm the steering is almost locking in place. I have checked the fluid and its full. What could be causing the steering to lock up. Its almost impossible to turn to the left..but it still can turn to the right. I am running a right hand prop. It gets worse the more I trim it.

I had a 1987 Baja 22 Force and now have a 1991 Baja 260, both got the same problem, replaced steering cable each time and problem fixed.
