Steering cable '02 22IR

[dejoeco]

I need to know what back mount steering cable to buy for my '02 22IR. I replaced it once before and I seem to remember that the recommended length was longer that what was originally in the boat. Also, is it normal to replace every 3 years? Best place to purchase?

Any help would be appreciated.
