Crazy and sad the boat sat so long and never got finished. I'm guessing that if the engine was installed in 2005, the hull is a 2005? That leaves a lot of room for a variety of engines if you don't want to use the QSC.
Price out a hull/top, engine/gear/drivetrain, and all the extras now a days and see where you're at. I bet it's gone before the weekend is over.
