When two boats share the same hull type — in this case both the Larson LXi 208 I/O 2006 and the Larson Senza 186 O/B 2007 are modified vee designs with composite 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 Senza 186 O/B 2007 measures 18,0 feet overall (2007), giving it roughly 16,0 additional feet of deck space compared to the Larson LXi 208 I/O 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Larson LXi 208 I/O 2006 tips the scales at 3 245 lbs — 1 460 lbs more than the Larson Senza 186 O/B 2007 at 1 785 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 Senza 186 O/B 2007 tops out at 175 hp. Engine specs for the Larson LXi 208 I/O 2006 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 29 gal and 29 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Larson LXi 208 I/O 2006 is rated for 9 passengers, while the Larson Senza 186 O/B 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson LXi 208 I/O 2006 could be the deciding factor.
Bottom line: Choose the Larson LXi 208 I/O 2006 if your priority is putting more people on the water — it handles 9 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Larson Senza 186 O/B 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
