When two boats share the same hull type — in this case both the Larson 1750 LX 2009 and the Larson LX 620 SF 2011 are modified vee designs with fiberglass 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 1750 LX 2009 at 17,1 ft versus Larson LX 620 SF 2011 at 16,2 ft. At 204 lbs and 115 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.
The Larson LX 620 SF 2011 tops out at 90 hp. Engine specs for the Larson 1750 LX 2009 aren't listed — confirm with a dealer before selecting an outboard.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 1750 LX 2009 is rated for 7 passengers, while the Larson LX 620 SF 2011 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 2009 could be the deciding factor.
Bottom line: Choose the Larson 1750 LX 2009 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 LX 620 SF 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
