What gives here?? I bought this brand new and now I have to bring it back for a second lower unit. Anyone else experience this frustrating acurance? Wouldn't you know it...The first one went on our July Vacation, this time its our August Vacation. I am wishing I bought a boat with a Yamaha now! The dealer replaced the entire lower unit the first time. This time I have the same symptom, metal in the gear oil. I am about to call them and let them now whats up...Hope thay are as good to me as the first time.
