Detailed Evaluation & Buyer Recommendation

Larson LX 185 S I/O 2013 vs Larson LXi 258 2009 — Same Brand, Different Boat

Matching a deep vee Larson LX 185 S I/O 2013 against a modified vee Larson LXi 258 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Larson LXi 258 2009 measures 25,0 feet overall (2009), giving it roughly 6,3 additional feet of deck space compared to the Larson LX 185 S I/O 2013 at 18,7 feet (2013). Weight tells a clearer story for trailering families: the Larson LXi 258 2009 tips the scales at 475 lbs — 271 lbs less than the Larson LX 185 S I/O 2013 at 204 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 Larson LX 185 S I/O 2013 carries a rated maximum of 135 hp. Engine data for the Larson LXi 258 2009 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson LXi 258 2009 carries 56 gallons versus 19 gallons in the Larson LX 185 S I/O 2013. 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 LXi 258 2009 is rated for 12 passengers, while the Larson LX 185 S I/O 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 258 2009 could be the deciding factor.

Bottom line: Choose the Larson LXi 258 2009 if your priority is putting more people on the water — it handles 12 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Larson LX 185 S I/O 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
