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. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Which is easier to trailer — the Larson Cabrio 274 2005 or the Larson SEi 180 Fish Series O/B 2005?
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. 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.

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.
How many people can each boat hold?
The Larson Cabrio 274 2005 is Coast Guard rated for 8 passengers, while the Larson SEi 180 Fish Series O/B 2005 is certified for 8.
