Re: Steering Adjustmants
First you need to find out where it's stiff. Start by removing the steering arm from the cable at the motor. Once it's loose, twist the outboard and see if that frees it up or not. If it does, then odds are the problem lies in the tilt-tube where the cable goes through the bracket at the motor. If that's it, you need to try and get the cable out and then take a shotgun cleaning brush or something similar to clean out the old grease in there and reapply. If, however, once you unhook that the motor is still stiff to turn, there are grease zerks, should be two, that you'll want to apply grease to until the old grease is all out of the king pin and replaced with new.
Welcome to iboats, and for more and better help, post pics of any further areas of concern. Good luck.
