It’s a g’day to take on the outback! The Moomba Outback Sport Boat 2008 is a true AWSA tournament qualified waterski boat, making every day on the water more than a g’day – it’s more like a great day! Powered by a 325hp 5.7 V8 EFI engine, the Outback lets you make the most of your slalom sets. For 2008, this Moomba sport boat features a brand new gelcoat pattern, new carpet, new stereo and upgraded cabin appointments, plus a back seat that can function as an extension of the sundeck.
