I have a problem with a DP-SM sterndrive with a 5.0 gl pwtr engine.We replaced the gimball bearing,had everything lined,checked the prop shaft for play and put everything back together again.It went good for 2 hours,after wich there was a vibration in the sterndrive when it was in the left or right position not in straight forward.So i should think it's the prop shaft.W're going to get the boat out of the water and check it all again.If somebody has an idea,I don't know.
