2011 VLX Maiden Voyage - Couple of problems

Took out the VLX today, We had a great day on the water, really nice weather. The boat had .7 hours on it when I picked it up. Assuming this is from Malibu testing it.... we did have a couple of items I wanted to ask for some help on.

The first is in the Vdrive compartment/rear of boat, there is a faint whistling/annoying/high pitch sound at 30-35 mph. I dont recall what the RPM's were, but my wife and daughter noticed it immediately. Its harder to hear from the drivers seat, but you can definitely hear it from the rear seating area. I called the dealer on the water, they told me the last 10 boats they have demo'd have this noise, and people have mad a comment about it.... they sell both PCM and Indmar, and both engine makes are producing this whistling. My supra never had this, does anyone know what this might be? The motor ran strong, trans shifted perfect, no signs of trouble from an operating standpoint. The dealer said use it until the 20 hr service and if its still making the sound they will take a look at it.

Second, I had a lot of water in my bilge area, the auto bilge warning came on a few times throughout the day. After I pulled the boat there was about 2" of water in the front drain plug area, so I pulled it and drained the water. I cant believe this is normal, the only time my Supra started having water in the bilge was when the dripless shaft seal started leaking. But this was after 230 hours of use.... I was going to throw it on the fake-a-lake this week and see if I can see where it might be coming from. I am thinking maybe the dripless shaft seal could be defective or leaking? I doubt any of the thru-hulls or drain plugs would be allowing this much water to come through. I am hoping I dont have a cracked ballast tank/fitting. I was filling and draining the tanks all day. Anyone have any ideas?

Thanks for any information you can pass my way
