For trailering, the Larson Cabrio 274 2005 has the edge at 6 lbs dry weight versus 1 785 lbs for the Larson SEi 180 Fish Series O/B 2005.

The Larson SEi 180 Fish Series O/B 2005 has a documented max rating of 175 hp. Engine specifications for the Larson Cabrio 274 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

The Larson Cabrio 274 2005 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.

Detailed Evaluation & Buyer Recommendation

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

The Larson Cabrio 274 2005 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 Larson SEi 180 Fish Series O/B 2005 tops out at 175 hp. Engine specs for the Larson Cabrio 274 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson Cabrio 274 2005 carries 85 gallons versus 29 gallons in the Larson SEi 180 Fish Series O/B 2005.
