I have a 1989 Larson San Marino. The last couple of trips out last year the steering seemed to be a bit stiff at first but would free up after a few turns, I thought maybe it was just me. When I had the marina winterize it they noticed the same thing and said I should have it checked in the spring. It is a 5.7 Mercruiser with an Alpha outdrive. Does anyone have any thoughts on what it might be. Thanks
