Moomba Gravity XLV 2011 vs Moomba Outback LSV 2004 — Same Brand, Different Boat

The Moomba Gravity XLV 2011 vs Moomba Outback LSV 2004 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.

Both boats share a closely matched power ceiling — 325 hp for the Moomba Gravity XLV 2011 and 310 hp for the Moomba Outback LSV 2004. 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. Both carry nearly identical fuel loads — 5 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Moomba Gravity XLV 2011 is rated for 16 passengers, while the Moomba Outback LSV 2004 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Gravity XLV 2011 could be the deciding factor.

Bottom line: Choose the Moomba Gravity XLV 2011 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 LSV 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Moomba Gravity XLV 2011 vs Moomba Outback LSV 2004 — Common Questions

Which is easier to trailer — the Moomba Gravity XLV 2011 or the Moomba Outback LSV 2004?
For trailering, the Moomba Outback LSV 2004 has the edge at 3 lbs dry weight versus 36 lbs for the Moomba Gravity XLV 2011. 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.
Which boat can handle a bigger outboard?
The Moomba Gravity XLV 2011 is rated to a maximum of 325 hp, giving it the larger power ceiling. The Moomba Outback LSV 2004 tops out at 310 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Moomba Gravity XLV 2011 is Coast Guard rated for 16 passengers, while the Moomba Outback LSV 2004 is certified for 10. 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.
How do the fuel tanks compare on the Moomba Gravity XLV 2011 and Moomba Outback LSV 2004?
Both boats carry similar fuel loads — 5 gallons and 4 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Moomba Gravity XLV 2011 and Moomba Outback LSV 2004 from the same manufacturer?
Yes — both the Moomba Gravity XLV 2011 and the Moomba Outback LSV 2004 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.
