My steering is very stiff. After pumping copious amounts of grease and changing out every other part (hydraulic helm, hydraulic lines and hydraulic tube) I have come to the conclusion the swivel bracket is stiff from corrosion or something else. My guess is corrosion around swivel bushing etc. Has anyone encountered this problem and found a cost effective solution. I understand the only true way is dismantling the power head and removing, replacing and cleaning the swivel tube and bushings. I wish I would of found all of this out before replacing every other part.
