Larson LX 850 I/O 2011 vs Larson Marine San Marino 1990 — Same Brand, Different Boat

The Larson LX 850 I/O 2011 vs Larson Marine San Marino 1990 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 260 hp, the Larson Marine San Marino 1990 has a 35-hp advantage over the Larson LX 850 I/O 2011's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Larson Marine San Marino 1990 at 25,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Larson LX 850 I/O 2011 at 18,4 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Larson LX 850 I/O 2011 vs Larson Marine San Marino 1990 — Common Questions

Which is the larger boat — the Larson LX 850 I/O 2011 or the Larson Marine San Marino 1990?
The Larson Marine San Marino 1990 is the longer of the two at 25,0 feet overall. The Larson LX 850 I/O 2011 comes in at 18,4 feet, making it roughly 6,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Larson Marine San Marino 1990 is rated to a maximum of 260 hp, giving it the larger power ceiling. The Larson LX 850 I/O 2011 tops out at 225 hp.

How many people can each boat hold?
The Larson LX 850 I/O 2011 is Coast Guard rated for 7 passengers, while the Larson Marine San Marino 1990 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Are the Larson LX 850 I/O 2011 and Larson Marine San Marino 1990 from the same manufacturer?
Yes — both the Larson LX 850 I/O 2011 and the Larson Marine San Marino 1990 are built by Larson. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
