Comments:

I am dismantling the steering cables from the wheel back to the rack and pinion (they are worn and rusted almost solid and the gears are starting to strip). I want to replace all parts from the wheel back to the rack and pinion. My problem is that I do not know how to dismantle the steering cable from the rack and pinion unit. I have the MerCruiser book for my year and setup but it does not get into the disassembling process. Can you tell me what has to be done and recommend a replacement unit to connect to the rack and pinion??

Our Response:

There are several common types and manufacturers of steering systems. The most popular are rack/n/pinion and rotary. 

 There are three major manufacturers and several that are out of business. (Morse, Tele-flex, U-flex, Det-Mar, etc.) Each has it's own assembly procedures and technique.

Due to production costs and packaging, it is less expensive to purchase the helm assembly and the steering cable as a kit then to buy just the service replacement cable by itself. A Morse rack/n/pinion steering kit starts at $147 to $160.

See web site for how to measure: and/or look at the printing on the cable for dimensions. The cable length is usually listed in inches, on the cable.

Once you have the new cable kit; you will be able to see how it is assembled and it also comes with instructions.
