I have a tight steering problem with my 1993 270 Sundancer. It has always been hard to steer since I bought it which was 20 years ago. I've replaced power steering parts over the years but there was never any improvement. Last year I replaced the power steering pump but no change. This year I decided to take it to an authorized Sea Ray dealer and have them fix it once and for all. They said that unfortunately they only service what they sell. Is this true of all Sea Ray dealers? Why can't I get my Sea Ray serviced by an authorized Sea Ray dealer?
