I know there have been other questions like this but your talking to a rookie boat owner and not extremely mechanically inclined
. Please try to make your answers as simple as possible. I looked at the steering on my 17' Larson bow rider with a Johnson outboard. There is an arm attached to the moter. There was grease at the joint of this arm. A hose lead from there up to the steering column. On the underside of the steering the round column met with a long retangular metal box. It was mounted similar to the wings of an airplane. The cable attached to the end of this box. Is this the tube that should be removed and filled with penetrating lube?
