Welcome to the forum Pete. That would be just too tempting, living that close to your FW dealer. I would be broke!
There is very little (if any that I can remember) ownership participation for the 180 OB on this forum. Not that people don't like it, the boat simply hasn't been on the market for very long.
There is a very recent discussion on the projected top speed of the SS version with a 150 Etec...

I was a bit thrown back at the transom styling when they first introduced it, but that has grown on me. The boat has a fairly deep vee for a 18 ft bowrider, so it tends to sacrafice some speed for excellent choppy wate handling. That holds true for the I/O or OB model.
Good luck with the shopping!
