I am interested in purchasing a 1994 sea ray laguna with 175 merc o/b. I am a little new to boating and am nervous about a 12 y/o motor. I do believe it was owned by an older woman and well maintained over the years by a reputable mechanic. It has been kept in the water over the years in the NY area. It looks to be in great condition. Should I stay away from a motor this old?
