The Moomba Mobius LS 2006 vs Moomba Outback LS 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Moomba Mobius LS 2006 measures 21,0 feet overall (2006), giving it roughly 19,0 additional feet of deck space compared to the Moomba Outback LS 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Moomba Outback LS 2005 tips the scales at 295 lbs — 264 lbs less than the Moomba Mobius LS 2006 at 31 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 340 hp, the Moomba Mobius LS 2006 has a 30-hp advantage over the Moomba Outback LS 2005's 310-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 34 gal and 34 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Moomba Mobius LS 2006 is rated for 13 passengers, while the Moomba Outback LS 2005 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Mobius LS 2006 could be the deciding factor.
Bottom line: Choose the Moomba Mobius LS 2006 if your priority is putting more people on the water — it handles 13 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Moomba Outback LS 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
