Larson FX 1850 DC O/B 2013 vs Larson SEi 210 I/O 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson FX 1850 DC O/B 2013 or the Larson SEi 210 I/O 2004?

For trailering, the Larson SEi 210 I/O 2004 has the edge at 29 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.

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

The Larson FX 1850 DC O/B 2013 has a documented max rating of 175 hp. Engine specifications for the Larson SEi 210 I/O 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 Larson FX 1850 DC O/B 2013 is Coast Guard rated for 7 passengers, while the Larson SEi 210 I/O 2004 is certified for 6. 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 210 I/O 2004 measures 99" 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.

Q: Which boat has the larger fuel tank — the Larson FX 1850 DC O/B 2013 or the Larson SEi 210 I/O 2004?

The Larson SEi 210 I/O 2004 has the bigger tank at 35 gallons, versus 3 gallons on the Larson FX 1850 DC O/B 2013. That 32-gallon difference translates to roughly 96–160 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson FX 1850 DC O/B 2013 and Larson SEi 210 I/O 2004 from the same manufacturer?

Yes — both the Larson FX 1850 DC O/B 2013 and the Larson SEi 210 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 FX 1850 DC O/B 2013 vs Larson SEi 210 I/O 2004 — Same Brand, Different Boat

The Larson FX 1850 DC O/B 2013 vs Larson SEi 210 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 Larson FX 1850 DC O/B 2013 carries a rated maximum of 175 hp. Engine data for the Larson SEi 210 I/O 2004 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson SEi 210 I/O 2004 carries 35 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 FX 1850 DC O/B 2013 is rated for 7 passengers, while the Larson SEi 210 I/O 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson FX 1850 DC O/B 2013 could be the deciding factor.

Bottom line: Choose the Larson FX 1850 DC O/B 2013 if your priority is putting more people on the water — it handles 7 passengers and at 18,5 ft it has the deck room to back that rating up comfortably. The Larson SEi 210 I/O 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
