Larson 274 Cabrio 2010 vs Larson SEi 180 Fish Series O/B 2005 — Same Brand, Different Boat

The Larson 274 Cabrio 2010 vs Larson SEi 180 Fish Series O/B 2005 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 375 hp, the Larson 274 Cabrio 2010 has a 200-hp advantage over the Larson SEi 180 Fish Series O/B 2005's 175-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 274 Cabrio 2010 carries 85 gallons versus 29 gallons in the Larson SEi 180 Fish Series O/B 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: Performance buyers should lean toward the Larson 274 Cabrio 2010 and its 375-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Larson SEi 180 Fish Series O/B 2005 with its 175-hp rating is the more economical daily driver.

Larson 274 Cabrio 2010 vs Larson SEi 180 Fish Series O/B 2005 — Common Questions

Which is easier to trailer — the Larson 274 Cabrio 2010 or the Larson SEi 180 Fish Series O/B 2005?
For trailering, the Larson 274 Cabrio 2010 has the edge at 6 lbs dry weight versus 1 785 lbs for the Larson SEi 180 Fish Series O/B 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Larson 274 Cabrio 2010 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Larson SEi 180 Fish Series O/B 2005 tops out at 175 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.
How many passengers can the Larson SEi 180 Fish Series O/B 2005 carry?
The Larson SEi 180 Fish Series O/B 2005 has an official capacity rating of 8 people. Capacity data wasn't available for the other model in this comparison — verify directly with the dealer.
Which boat is wider, and does it affect trailering?
The Larson 274 Cabrio 2010 measures 102" wide, compared to 93" for the Larson SEi 180 Fish Series O/B 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Larson 274 Cabrio 2010 or the Larson SEi 180 Fish Series O/B 2005?
The Larson 274 Cabrio 2010 has the bigger tank at 85 gallons, versus 29 gallons on the Larson SEi 180 Fish Series O/B 2005. That 56-gallon difference translates to roughly 168–280 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson 274 Cabrio 2010 and Larson SEi 180 Fish Series O/B 2005 from the same manufacturer?
Yes — both the Larson 274 Cabrio 2010 and the Larson SEi 180 Fish Series O/B 2005 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.
