Moomba Gravity XLV 2012 vs Moomba Outback LS 2007 — Same Brand, Different Boat

The Moomba Gravity XLV 2012 vs Moomba Outback LS 2007 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.

On paper these two are close siblings in the size department — Moomba Gravity XLV 2012 at 23,0 ft versus Moomba Outback LS 2007 at 21,0 ft. At 36 lbs and 31 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 325 hp for the Moomba Gravity XLV 2012 and 325 hp for the Moomba Outback LS 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Moomba Outback LS 2007 carries 34 gallons versus 5 gallons in the Moomba Gravity XLV 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Moomba Gravity XLV 2012 is rated for 16 passengers, while the Moomba Outback LS 2007 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Gravity XLV 2012 could be the deciding factor.

Bottom line: Choose the Moomba Gravity XLV 2012 if your priority is putting more people on the water — it handles 16 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Moomba Outback LS 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.

Moomba Gravity XLV 2012 vs Moomba Outback LS 2007 — Common Questions

Which is the larger boat — the Moomba Gravity XLV 2012 or the Moomba Outback LS 2007?
The Moomba Gravity XLV 2012 is the longer of the two at 23,0 feet overall. The Moomba Outback LS 2007 comes in at 21,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Moomba Gravity XLV 2012 or the Moomba Outback LS 2007?
For trailering, the Moomba Outback LS 2007 has the edge at 31 lbs dry weight versus 36 lbs for the Moomba Gravity XLV 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Moomba Gravity XLV 2012 is Coast Guard rated for 16 passengers, while the Moomba Outback LS 2007 is certified for 13. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the larger fuel tank — the Moomba Gravity XLV 2012 or the Moomba Outback LS 2007?
The Moomba Outback LS 2007 has the bigger tank at 34 gallons, versus 5 gallons on the Moomba Gravity XLV 2012. That 29-gallon difference translates to roughly 87–145 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Moomba Gravity XLV 2012 and Moomba Outback LS 2007 from the same manufacturer?
Yes — both the Moomba Gravity XLV 2012 and the Moomba Outback LS 2007 are built by Moomba. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
