i have 2000 bayliner 17.5 capri with a 135 merc inboard and rack and pinion steering and an alpha1 outdrive. this is a two part question 1st i think the steering cable is shot. i tried wd40 then marine grease and it still steers hard. i read an article that says you should not grease at all. second would it be expensive to convert to power steering it is a 400.00 option when you buy the boat brand new. i use it primarily for wake boarding and i have a tower on it. or just replace the cable and rack.
