Moomba Mobius XLV 2005 vs Moomba Outback V 2011 — Same Brand, Different Boat

The Moomba Mobius XLV 2005 vs Moomba Outback V 2011 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 XLV 2005 measures 23,0 feet overall (2005), giving it roughly 21,0 additional feet of deck space compared to the Moomba Outback V 2011 at 2,0 feet (2011). At 36 lbs and 32 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 — 310 hp for the Moomba Mobius XLV 2005 and 325 hp for the Moomba Outback V 2011. 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 V 2011 carries 39 gallons versus 4 gallons in the Moomba Mobius XLV 2005. 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 Mobius XLV 2005 is rated for 16 passengers, while the Moomba Outback V 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Moomba Mobius XLV 2005 could be the deciding factor.

Bottom line: Choose the Moomba Mobius XLV 2005 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 V 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

Moomba Mobius XLV 2005 vs Moomba Outback V 2011 — Common Questions

Which is the larger boat — the Moomba Mobius XLV 2005 or the Moomba Outback V 2011?
The Moomba Mobius XLV 2005 is the longer of the two at 23,0 feet overall. The Moomba Outback V 2011 comes in at 2,0 feet, making it roughly 21,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Moomba Mobius XLV 2005 or the Moomba Outback V 2011?
For trailering, the Moomba Outback V 2011 has the edge at 32 lbs dry weight versus 36 lbs for the Moomba Mobius XLV 2005. 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 Outback V 2011 is rated to a maximum of 325 hp, giving it the larger power ceiling. The Moomba Mobius XLV 2005 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 Mobius XLV 2005 is Coast Guard rated for 16 passengers, while the Moomba Outback V 2011 is certified for 12. 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 is wider, and does it affect trailering?
The Moomba Mobius XLV 2005 measures 98" wide, compared to 96" for the Moomba Outback V 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Moomba Mobius XLV 2005 or the Moomba Outback V 2011?
The Moomba Outback V 2011 has the bigger tank at 39 gallons, versus 4 gallons on the Moomba Mobius XLV 2005. That 35-gallon difference translates to roughly 105–175 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Moomba Mobius XLV 2005 and Moomba Outback V 2011 from the same manufacturer?
Yes — both the Moomba Mobius XLV 2005 and the Moomba Outback V 2011 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.
