ok... just ran across this thread...
I've had my NS2200 for a year and a half now... most of these issues you've brought up sound like dealer related items to me... here's a few thoughts...
1) Two month delivery for a boat order doesn't sound unreasonable to me....
2) Sounds to me like you ordered "custom" (different) plates than the factory usually supplies

They should have had them installed (if they could get them in time)... but if it came without them, I can't understand why you haven't had your dealer take care of this issue... even if they have to supply them and install them themselves. A "Good" dealership takes care of good customers, and (assuming you are a customer they ever want to see again) I don't understand why your dealer hasn't resolved the issue for you or why you are trying to deal directly with the manufacturer.
3) Why is your dealer not solving this issue for you?
4) I REALLY don't understand why your dealer isn't solving this issue for you...
5) MINE came with the oil tank installed in FRONT of the battery.... I *THINK* this is a dealer installation item when rigging the motor (unless it came this way from the factory). Again.... I fail to understand why this wasn't addressed by your Dealer...

assuming that you DID bring it to their attention?
6) Gauges properly sealed won't get condensation... why isn't your dealer fixing this?
7) Sounds like poor factory work... but should have been addressed by your dealer if you brought it to their attention...

9) See #7.
10) Sometimes when it's rough, I have water overflow from the front livewell and run around the console and drip on my feet if I have them all the way forward... usually I either stand with my feet slightly further back, or sit on the leaning post and use the footrest to keep my feet from being dripped on when I'm running with a full front livewell in rough seas. I see no way to easily rectify this problem without taking the time to find a way to "seal" the front livewell, and I haven't taken the time to give this a shot yet.

12)

Where else would the switches go? This is the same general area on the console that most every other manufacturer out there uses. I haven't had any issues with any of my switches yet, and although I agree that it would be easy to turn one on unintentionally, I see that being no different than it would be with any other brand of boat. Maybe you need to fabricate some sort of "cover" for the switches if you're somehow hitting them inadvertently on a regular basis? Anyway... this hasn't been an issue for me yet.
13) I have to disagree with you on this one. Most of the people that I know with "Bay Boats" (and I know a LOT of them) do NOT have a depth finder up front. The tubes are there for line access... how hard can it be for you to run a new wire through there? If it's that difficult for you, have the dealer perform the installation.
14)

My dealer explained this to me when I bought the boat.... no big deal... put the plug in place and leave it there unless you're draining the box.
15) I have posted this issue multiple times in my earlier posts... perform a search and you'll see that..... nothing that can't be fixed with a tube of 4200 and an hour and 15 minutes or so of your time. I do agree that IMO the factory should do this... but apparently not every user has this problem... maybe we use ours harder than some?
16) This is IMO a design flaw... the seat WILL have stress on the strap that will eventually cause it to fail because every time you get off the seat you cause it to pull on the strap. If you're as large and heavy as I am, it WILL eventually fail. Simple solution to this is to use a "bungee" type cord to secure the seat... it allows the seat to move slightly without breaking the strap, or stripping the screws. I've never had a problem with the limiting strap... maybe you stressed/abused yours unintentionally?
17) I'm 6'2" and 225 and do NOT have this issue. See #7 above.
Overall it sure sounds to me like your dealer is maybe not as responsive as they should be. However, having not heard their side of the story, I'll hold off on judging them as being incompetent just yet....
If there IS a reason why you're dealing with the factory instead of asking your dealer to resolve your issues, please let us know what it is.
