Larson 1850 LX 2010 vs Larson SEi 190 I/O 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson 1850 LX 2010 or the Larson SEi 190 I/O 2004?

For trailering, the Larson SEi 190 I/O 2004 has the edge at 265 lbs dry weight versus 2 375 lbs for the Larson 1850 LX 2010. 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 Larson 1850 LX 2010 is rated to a maximum of 190 hp, giving it the larger power ceiling. The Larson SEi 190 I/O 2004 tops out at 150 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 Larson 1850 LX 2010 is Coast Guard rated for 7 passengers, while the Larson SEi 190 I/O 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.

Q: Which boat is wider, and does it affect trailering?

The Larson SEi 190 I/O 2004 measures 94" wide, compared to 88" for the Larson 1850 LX 2010. 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: Which boat has the larger fuel tank — the Larson 1850 LX 2010 or the Larson SEi 190 I/O 2004?

The Larson SEi 190 I/O 2004 has the bigger tank at 29 gallons, versus 23 gallons on the Larson 1850 LX 2010. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson 1850 LX 2010 and Larson SEi 190 I/O 2004 from the same manufacturer?

Yes — both the Larson 1850 LX 2010 and the Larson SEi 190 I/O 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.

Detailed Evaluation & Buyer Recommendation

Larson 1850 LX 2010 vs Larson SEi 190 I/O 2004 — Same Brand, Different Boat

The Larson 1850 LX 2010 vs Larson SEi 190 I/O 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 190 hp, the Larson 1850 LX 2010 has a 40-hp advantage over the Larson SEi 190 I/O 2004's 150-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 SEi 190 I/O 2004 carries 29 gallons versus 23 gallons in the Larson 1850 LX 2010. 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 1850 LX 2010 is rated for 7 passengers, while the Larson SEi 190 I/O 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 1850 LX 2010 could be the deciding factor.

Bottom line: Choose the Larson 1850 LX 2010 if your priority is putting more people on the water — it handles 7 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Larson SEi 190 I/O 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.
