Moomba Gravity XLV 2012 vs Moomba Mobius XLV 2004 — Same Brand, Different Boat

The Moomba Gravity XLV 2012 vs Moomba Mobius XLV 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 2012 and 310 hp for the Moomba Mobius XLV 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.

Both boats are rated for 16 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Moomba Gravity XLV 2012 and Moomba Mobius XLV 2004 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Moomba Gravity XLV 2012 vs Moomba Mobius XLV 2004 — Common Questions

Which is easier to trailer — the Moomba Gravity XLV 2012 or the Moomba Mobius XLV 2004?
For trailering, the Moomba Gravity XLV 2012 has the edge at 36 lbs dry weight versus 41 lbs for the Moomba Mobius XLV 2004. 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 2012 is rated to a maximum of 325 hp, giving it the larger power ceiling. The Moomba Mobius XLV 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 2012 is Coast Guard rated for 16 passengers, while the Moomba Mobius XLV 2004 is certified for 16. 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 2012 and Moomba Mobius XLV 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 2012 and Moomba Mobius XLV 2004 from the same manufacturer?
Yes — both the Moomba Gravity XLV 2012 and the Moomba Mobius XLV 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.
