Kilty,
I would check the oil and the coolant level. Test fire the boat in your driveway to make sure everythings a go. You can run it for a few seconds without a hose connection so dont worry. If she fires up you know when you launch it at the lake it'll start up.
Before launching make sure the bilge plug is installed(easy to forget on a new boat) and back it down the ramp but do not release it from the trailer for several minutes. What you want to do is since the boat has never been in the water you need to be certain all the fittings and so forth are good. After several minutes example the bilge through the engine hatch door and if all is dry then release from trailer and start her up but stay close to the dock to be 100% sure all is good. There have been reports of new boats having QC issues with hoses popping off and the like.
Now.....Even though your boat is new you have a problem that you probably are not aware of. In 2007 they used ceramic washers in the supercharger. These are prone to fail and when they do they can cause massive engine failure. You will want to have the ceramic supercharger washers replaced with the new Steel washers. I would do this at the 10 hour service.
Finally, if you hate your boat please sell it to me!!! I want a C-180!!!
