Larson Marine Cabrio 274 2006 vs Larson SEi 180 I/O 2004 - Boat Spec Comparison

Q: Which boat can handle a bigger outboard?

The Larson Marine Cabrio 274 2006 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Larson SEi 180 I/O 2004 tops out at 150 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Larson Marine Cabrio 274 2006 is Coast Guard rated for 8 passengers, while the Larson SEi 180 I/O 2004 is certified for 5. 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.

Q: Which boat has the larger fuel tank - the Larson Marine Cabrio 274 2006 or the Larson SEi 180 I/O 2004?

The Larson Marine Cabrio 274 2006 has the bigger tank at 85 gallons, versus 23 gallons on the Larson SEi 180 I/O 2004. That 62-gallon difference translates to roughly 186–310 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson Marine Cabrio 274 2006 and Larson SEi 180 I/O 2004 from the same manufacturer?

Yes - both the Larson Marine Cabrio 274 2006 and the Larson SEi 180 I/O 2004 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.

Detailed Evaluation & Buyer Recommendation

Larson Marine Cabrio 274 2006 vs Larson SEi 180 I/O 2004: Same Brand, Different Boat

The Larson Marine Cabrio 274 2006 vs Larson SEi 180 I/O 2004 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 320 hp, the Larson Marine Cabrio 274 2006 has a 170-hp advantage over the Larson SEi 180 I/O 2004's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Larson Marine Cabrio 274 2006 carries 85 gallons versus 23 gallons in the Larson SEi 180 I/O 2004. 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 Marine Cabrio 274 2006 is rated for 8 passengers, while the Larson SEi 180 I/O 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Marine Cabrio 274 2006 could be the deciding factor.

Bottom line: Choose the Larson Marine Cabrio 274 2006 if your priority is putting more people on the water - it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Larson SEi 180 I/O 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
