When two boats share the same hull type — in this case both the Larson Cabrio 310 2007 and the Larson FX 1750 DC O/B 2012 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?

Size is the most obvious dividing line here. The Larson Cabrio 310 2007 measures 31,0 feet overall (2007), giving it roughly 13,6 additional feet of deck space compared to the Larson FX 1750 DC O/B 2012 at 17,4 feet (2012). At 104 lbs and 17 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 FX 1750 DC O/B 2012 tops out at 150 hp. Engine specs for the Larson Cabrio 310 2007 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson FX 1750 DC O/B 2012 carries 23 gallons versus 16 gallons in the Larson Cabrio 310 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Larson Cabrio 310 2007 is rated for 9 passengers, while the Larson FX 1750 DC 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 Cabrio 310 2007 could be the deciding factor.
