Just had my lower unit replaced about a month ago from hitting an underwater obstruction....Was almost completely through with the break in period when tonight I'm out fishing and start to sit my boat up on pad and hear that terrible noise of a hub spinning, so I thought.....I trimmed my motor up and be danged if the prop wasnt gone....The prop shaft had broke completely down inside the lower unit....So now the prop and the rest of the prop shaft are laying somewhere out in 30ft...This is really frustrating
