The Larson 1700 LX 2010 is a modified-V design and the Larson FX 1750 SC 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 1700 LX 2010 at 16,9 ft versus Larson FX 1750 SC O/B 2013 at 17,4 ft. Weight tells a clearer story for trailering families: the Larson FX 1750 SC O/B 2013 tips the scales at 1 999 lbs - 349 lbs less than the Larson 1700 LX 2010 at 1 650 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 150 hp, the Larson FX 1750 SC O/B 2013 has a 35-hp advantage over the Larson 1700 LX 2010's 115-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 22 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Larson 1700 LX 2010 is rated for 7 passengers, while the Larson FX 1750 SC 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 1700 LX 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Larson FX 1750 SC O/B 2013 comes in at 13 lbs per hp versus 14 lbs per hp for the Larson 1700 LX 2010. 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 1700 LX 2010 if your priority is putting more people on the water - it handles 7 passengers and at 16,9 ft it has the deck room to back that rating up comfortably. The Larson FX 1750 SC 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.
