Larson FX 1750 DC O/B 2013 vs Larson LX 185 S I/O 2013 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Larson FX 1750 DC O/B 2013 and the Larson LX 185 S I/O 2013 are deep vee designs with composite construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Larson FX 1750 DC O/B 2013 at 17,4 ft versus Larson LX 185 S I/O 2013 at 18,7 ft. Weight tells a clearer story for trailering families: the Larson FX 1750 DC O/B 2013 tips the scales at 2 133 lbs — 1 929 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.

Both boats share a closely matched power ceiling — 150 hp for the Larson FX 1750 DC O/B 2013 and 135 hp for the Larson LX 185 S I/O 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 22 gal and 19 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Larson LX 185 S I/O 2013 is rated for 7 passengers, while the Larson FX 1750 DC O/B 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LX 185 S I/O 2013 could be the deciding factor.

Bottom line: Choose the Larson LX 185 S I/O 2013 if your priority is putting more people on the water — it handles 7 passengers and at 18,7 ft it has the deck room to back that rating up comfortably. The Larson FX 1750 DC O/B 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Larson FX 1750 DC O/B 2013 vs Larson LX 185 S I/O 2013 — Common Questions

Which is the larger boat — the Larson FX 1750 DC O/B 2013 or the Larson LX 185 S I/O 2013?
The Larson LX 185 S I/O 2013 is the longer of the two at 18,7 feet overall. The Larson FX 1750 DC O/B 2013 comes in at 17,4 feet, making it roughly 1,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson FX 1750 DC O/B 2013 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 2 133 lbs for the Larson FX 1750 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 1750 DC O/B 2013 is rated to a maximum of 150 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.
How many people can each boat hold?
The Larson FX 1750 DC O/B 2013 is Coast Guard rated for 6 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.
Which boat is wider, and does it affect trailering?
The Larson FX 1750 DC O/B 2013 measures 96" wide, compared to 88" for the Larson LX 185 S I/O 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 1750 DC O/B 2013 or the Larson LX 185 S I/O 2013?
The Larson FX 1750 DC O/B 2013 has the bigger tank at 22 gallons, versus 19 gallons on the Larson LX 185 S I/O 2013. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson FX 1750 DC O/B 2013 and Larson LX 185 S I/O 2013 from the same manufacturer?
Yes — both the Larson FX 1750 DC O/B 2013 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.
