Larson LXi 258 I/O 2012 vs Larson SEi 180 O/B 2004 — Same Brand, Different Boat

The Larson LXi 258 I/O 2012 vs Larson SEi 180 O/B 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 power gap is worth calling out. Rated to 150 hp, the Larson SEi 180 O/B 2004 has a 147-hp advantage over the Larson LXi 258 I/O 2012's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson LXi 258 I/O 2012 carries 56 gallons versus 23 gallons in the Larson SEi 180 O/B 2004. 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 Larson LXi 258 I/O 2012 is rated for 12 passengers, while the Larson SEi 180 O/B 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 258 I/O 2012 could be the deciding factor.

Bottom line: Choose the Larson LXi 258 I/O 2012 if your priority is putting more people on the water — it handles 12 passengers and at 25,5 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 O/B 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Larson LXi 258 I/O 2012 vs Larson SEi 180 O/B 2004 — Common Questions

Which is easier to trailer — the Larson LXi 258 I/O 2012 or the Larson SEi 180 O/B 2004?
For trailering, the Larson SEi 180 O/B 2004 has the edge at 15 lbs dry weight versus 475 lbs for the Larson LXi 258 I/O 2012. 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 Larson SEi 180 O/B 2004 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Larson LXi 258 I/O 2012 tops out at 3 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 Larson LXi 258 I/O 2012 is Coast Guard rated for 12 passengers, while the Larson SEi 180 O/B 2004 is certified for 5. 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 Larson LXi 258 I/O 2012 measures 102" wide, compared to 93" for the Larson SEi 180 O/B 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.
Which boat has the larger fuel tank — the Larson LXi 258 I/O 2012 or the Larson SEi 180 O/B 2004?
The Larson LXi 258 I/O 2012 has the bigger tank at 56 gallons, versus 23 gallons on the Larson SEi 180 O/B 2004. That 33-gallon difference translates to roughly 99–165 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson LXi 258 I/O 2012 and Larson SEi 180 O/B 2004 from the same manufacturer?
Yes — both the Larson LXi 258 I/O 2012 and the Larson SEi 180 O/B 2004 are built by Larson. 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.
