Larson FX 1750 SC O/B 2012 vs Larson SEi 180 LX I/O 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Larson FX 1750 SC O/B 2012 or the Larson SEi 180 LX I/O 2008?

The Larson FX 1750 SC O/B 2012 is the longer of the two at 17,4 feet overall. The Larson SEi 180 LX I/O 2008 comes in at 17,0 feet, making it roughly 0,4 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Larson FX 1750 SC O/B 2012 or the Larson SEi 180 LX I/O 2008?

For trailering, the Larson FX 1750 SC O/B 2012 has the edge at 16 lbs dry weight versus 2 365 lbs for the Larson SEi 180 LX I/O 2008. 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 SEi 180 LX I/O 2008 is rated to a maximum of 225 hp, giving it the larger power ceiling. The Larson FX 1750 SC O/B 2012 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 FX 1750 SC O/B 2012 is Coast Guard rated for 6 passengers, while the Larson SEi 180 LX I/O 2008 is certified for 8. 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 has the better power-to-weight ratio?

The Larson FX 1750 SC O/B 2012 has a better power-to-weight ratio at 0 lbs per hp compared to 11 lbs per hp for the Larson SEi 180 LX I/O 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.

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

The Larson FX 1750 SC O/B 2012 measures 96" wide, compared to 93" for the Larson SEi 180 LX I/O 2008. 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: How do the fuel tanks compare on the Larson FX 1750 SC O/B 2012 and Larson SEi 180 LX I/O 2008?

Both boats carry similar fuel loads — 23 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Larson FX 1750 SC O/B 2012 and Larson SEi 180 LX I/O 2008 from the same manufacturer?

Yes — both the Larson FX 1750 SC O/B 2012 and the Larson SEi 180 LX I/O 2008 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 1750 SC O/B 2012 vs Larson SEi 180 LX I/O 2008 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Larson FX 1750 SC O/B 2012 and the Larson SEi 180 LX I/O 2008 are modified 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 SC O/B 2012 at 17,4 ft versus Larson SEi 180 LX I/O 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Larson SEi 180 LX I/O 2008 tips the scales at 2 365 lbs — 2 349 lbs less than the Larson FX 1750 SC O/B 2012 at 16 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 225 hp, the Larson SEi 180 LX I/O 2008 has a 75-hp advantage over the Larson FX 1750 SC O/B 2012's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Larson SEi 180 LX I/O 2008 is rated for 8 passengers, while the Larson FX 1750 SC O/B 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson SEi 180 LX I/O 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Larson FX 1750 SC O/B 2012 comes in at 0 lbs per hp versus 11 lbs per hp for the Larson SEi 180 LX I/O 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

The Larson SEi 180 LX I/O 2008 has a documented top speed of 41 mph. Speed data wasn't available for the other model.

Bottom line: Choose the Larson SEi 180 LX I/O 2008 if your priority is putting more people on the water — it handles 8 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Larson FX 1750 SC O/B 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
