Congrats on your purchase!
We have a Cobalt 250 Bowrider and we love it! I bought it used last year from an owner who meticulously maintained it and kept it on a covered boat lift. It is solid as a rock in the rough stuff and we have had 10 people on it and there is plenty of room. And, the 425HP big block with captain's call exhaust satisfies my occasional mid-life crisis and provides more power than we need.
Wish you the best with the Cobalt. I am sure you won't be disappointed!
