Where to find steering cable for 14' Rage

[DrScoles]

I bought a 92 or 93 rage. Steering is really stiff and notchy. Boat had been sitting for a while, the bracket than held the steering cable was rusted. Fixed that, but I'm afraid the whole cable is shot, or the bearings in the nozzle of the jet need to be replaced??

I can't find a manual online.

Thanks, Mike
