Larson 1850 LX 2010 vs Larson LX 185 S I/O 2013 - Boat Spec Comparison

Q: Which is the larger boat — the Larson 1850 LX 2010 or the Larson LX 185 S I/O 2013?

The Larson 1850 LX 2010 is the longer of the two at 18,8 feet overall. The Larson LX 185 S I/O 2013 comes in at 18,7 feet, making it roughly 0,2 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Larson 1850 LX 2010 or the Larson LX 185 S I/O 2013?

For trailering, the Larson LX 185 S I/O 2013 has the edge at 204 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 LX 185 S I/O 2013 tops out at 135 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 LX 185 S I/O 2013 is certified for 7. 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: Do these boats require an oversize trailer permit to tow on US highways?

Both the Larson 1850 LX 2010 and Larson LX 185 S I/O 2013 share an 7 ft. 4 in. (2.24 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Larson 1850 LX 2010 or the Larson LX 185 S I/O 2013?

The Larson 1850 LX 2010 has the bigger tank at 23 gallons, versus 19 gallons on the Larson LX 185 S I/O 2013. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson 1850 LX 2010 and Larson LX 185 S I/O 2013 from the same manufacturer?

Yes — both the Larson 1850 LX 2010 and the Larson LX 185 S I/O 2013 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 LX 185 S I/O 2013 — Same Brand, Different Boat

Matching a modified vee Larson 1850 LX 2010 against a deep vee Larson LX 185 S I/O 2013 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.

On paper these two are close siblings in the size department — Larson 1850 LX 2010 at 18,8 ft versus Larson LX 185 S I/O 2013 at 18,7 ft. Weight tells a clearer story for trailering families: the Larson 1850 LX 2010 tips the scales at 2 375 lbs — 2 171 lbs more than the Larson LX 185 S I/O 2013 at 204 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 190 hp, the Larson 1850 LX 2010 has a 55-hp advantage over the Larson LX 185 S I/O 2013's 135-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 1850 LX 2010 carries 23 gallons versus 19 gallons in the Larson LX 185 S I/O 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Larson 1850 LX 2010 and its 190-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Larson LX 185 S I/O 2013 with its 135-hp rating is the more economical daily driver.
