The Larson 1750 LX 2010 is a modified-V design and the Larson FX 1750 DC O/B 2013 is a deep-V design, so you're likely deciding between two noticeably 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 1750 LX 2010 at 17,1 ft versus Larson FX 1750 DC O/B 2013 at 17,4 ft. At 2 040 lbs and 2 133 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling - 150 hp for the Larson 1750 LX 2010 and 150 hp for the Larson FX 1750 DC O/B 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 - 23 gal and 22 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Larson 1750 LX 2010 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 1750 LX 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Larson 1750 LX 2010 comes in at 14 lbs per hp versus 14 lbs per hp for the Larson FX 1750 DC O/B 2013. 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.
Bottom line: Choose the Larson 1750 LX 2010 if your priority is putting more people on the water - it handles 7 passengers and at 17,1 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.
