I can check the noise in neutral ,run up the engine and I get no squeal. The shaft doesn't turn. So I know the noise isn't coming from the engine itself. Only when I am in drive does it squeal. As far as the warranty issue I believe it does say the warranty does not transfer. The issues I have with Marine Air is, they are supposedly a reputable company, it is a manufactures defect, and it happened before I owned the boat.
