Moomba Gravity XLV 2012 vs Moomba Outback 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Moomba Gravity XLV 2012 or the Moomba Outback 2004?

For trailering, the Moomba Gravity XLV 2012 has the edge at 36 lbs dry weight versus 275 lbs for the Moomba Outback 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.

Q: What is the maximum horsepower rating for these boats?

The Moomba Gravity XLV 2012 has a documented max rating of 325 hp. Engine specifications for the Moomba Outback 2004 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Moomba Gravity XLV 2012 is Coast Guard rated for 16 passengers, while the Moomba Outback 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.

Q: Which boat has the larger fuel tank — the Moomba Gravity XLV 2012 or the Moomba Outback 2004?

The Moomba Outback 2004 has the bigger tank at 28 gallons, versus 5 gallons on the Moomba Gravity XLV 2012. That 23-gallon difference translates to roughly 69–115 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Moomba Gravity XLV 2012 and Moomba Outback 2004 from the same manufacturer?

Yes — both the Moomba Gravity XLV 2012 and the Moomba Outback 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.

Detailed Evaluation & Buyer Recommendation

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

The Moomba Gravity XLV 2012 vs Moomba Outback 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.

The Moomba Gravity XLV 2012 carries a rated maximum of 325 hp. Engine data for the Moomba Outback 2004 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Moomba Outback 2004 carries 28 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 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 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 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.
