Larson FX 1850 DC O/B 2013 vs Larson LXi 258 I/O 2012 — Same Brand, Different Boat

Matching a deep vee Larson FX 1850 DC O/B 2013 against a modified vee Larson LXi 258 I/O 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Larson LXi 258 I/O 2012 measures 25,5 feet overall (2012), giving it roughly 7,0 additional feet of deck space compared to the Larson FX 1850 DC O/B 2013 at 18,5 feet (2013). Weight tells a clearer story for trailering families: the Larson FX 1850 DC O/B 2013 tips the scales at 2 219 lbs — 1 744 lbs more than the Larson LXi 258 I/O 2012 at 475 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 175 hp, the Larson FX 1850 DC O/B 2013 has a 172-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 3 gallons in the Larson FX 1850 DC O/B 2013. 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 FX 1850 DC O/B 2013 caps at 7. 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 FX 1850 DC O/B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Larson FX 1850 DC O/B 2013 vs Larson LXi 258 I/O 2012 — Common Questions

Which is the larger boat — the Larson FX 1850 DC O/B 2013 or the Larson LXi 258 I/O 2012?
The Larson LXi 258 I/O 2012 is the longer of the two at 25,5 feet overall. The Larson FX 1850 DC O/B 2013 comes in at 18,5 feet, making it roughly 7,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson FX 1850 DC O/B 2013 or the Larson LXi 258 I/O 2012?
For trailering, the Larson LXi 258 I/O 2012 has the edge at 475 lbs dry weight versus 2 219 lbs for the Larson FX 1850 DC O/B 2013. 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 FX 1850 DC O/B 2013 is rated to a maximum of 175 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 FX 1850 DC O/B 2013 is Coast Guard rated for 7 passengers, while the Larson LXi 258 I/O 2012 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 Larson LXi 258 I/O 2012 measures 102" wide, compared to 92" for the Larson FX 1850 DC O/B 2013. 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 FX 1850 DC O/B 2013 or the Larson LXi 258 I/O 2012?
The Larson LXi 258 I/O 2012 has the bigger tank at 56 gallons, versus 3 gallons on the Larson FX 1850 DC O/B 2013. That 53-gallon difference translates to roughly 159–265 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson FX 1850 DC O/B 2013 and Larson LXi 258 I/O 2012 from the same manufacturer?
Yes — both the Larson FX 1850 DC O/B 2013 and the Larson LXi 258 I/O 2012 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.
