Moomba Mobius LS 2008 vs Moomba Outback LS 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Moomba Mobius LS 2008 or the Moomba Outback LS 2004?

For trailering, the Moomba Outback LS 2004 has the edge at 295 lbs dry weight versus 315 lbs for the Moomba Mobius LS 2008. 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: Which boat can handle a bigger outboard?

The Moomba Mobius LS 2008 is rated to a maximum of 325 hp, giving it the larger power ceiling. The Moomba Outback LS 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.

Q: How many people can each boat hold?

The Moomba Mobius LS 2008 is Coast Guard rated for 13 passengers, while the Moomba Outback LS 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 is wider, and does it affect trailering?

The Moomba Mobius LS 2008 measures 97" wide, compared to 95" for the Moomba Outback LS 2004. 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.

Q: How do the fuel tanks compare on the Moomba Mobius LS 2008 and Moomba Outback LS 2004?

Both boats carry similar fuel loads — 34 gallons and 34 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Moomba Mobius LS 2008 and Moomba Outback LS 2004 from the same manufacturer?

Yes — both the Moomba Mobius LS 2008 and the Moomba Outback LS 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 Mobius LS 2008 vs Moomba Outback LS 2004 — Same Brand, Different Boat

The Moomba Mobius LS 2008 vs Moomba Outback LS 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 Mobius LS 2008 and 310 hp for the Moomba Outback LS 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 — 34 gal and 34 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Moomba Mobius LS 2008 is rated for 13 passengers, while the Moomba Outback LS 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 Mobius LS 2008 could be the deciding factor.

Bottom line: Choose the Moomba Mobius LS 2008 if your priority is putting more people on the water — it handles 13 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Moomba Outback LS 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.
