I'm assuming you bought the one from Sea Ray of Chicago? If so, welcome to the club! We're here to help!
Don't expect it to be a speed demon, that's a heavy boat, and with the 454, it'll probably push it around 35-40MPH on the top end.
The stainless radar arch IS stock from the factory.
The gauge cluster can be repaired, but not replaced. I did this on my boat, and you can read about in the How To section. It's a VERY complicated and expensive project, and if not done properly, can destroy the gauge cluster. If you can live with a small crack, and it's not getting any larger over time, then your best bet is to leave it alone. Unfortunately those parts were made in-house at the Mariah plant, and when they closed in 2001, all those molds and the parts stock they had were sold, and we have no idea where they made their way to. So, repairing it is your only option.
As far as everything else, we've compiled a Mariah Parts List which is available in the "Original Mariah Talk" section at the top. If you have a specific part you might have questions on, just post it. We'll help you as much as we can.
That is a good boat, I spoke personally with the previous owner, as well as the dealer. you got a hell of a deal on that boat, if i do say so myself. I was going to trade mine in for it, but got suckered into a kitchen remodeling project instead. you know how women can be.
So anyway, hope this helps you, and if you have questions, don't be afraid to ask. We'll help get you up to speed, and you'll feel right at home here.
