Larson Cabrio 350 2008 vs Larson SEi 180 Fish Series O/B 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson Cabrio 350 2008 or the Larson SEi 180 Fish Series O/B 2005?

For trailering, the Larson Cabrio 350 2008 has the edge at 14 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.

Q: Which boat can handle a bigger outboard?

The Larson Cabrio 350 2008 is rated to a maximum of 330 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.

Q: 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.

Q: Which boat is wider, and does it affect trailering?

The Larson Cabrio 350 2008 measures 144" 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.

Q: Which boat has the larger fuel tank — the Larson Cabrio 350 2008 or the Larson SEi 180 Fish Series O/B 2005?

The Larson SEi 180 Fish Series O/B 2005 has the bigger tank at 29 gallons, versus 23 gallons on the Larson Cabrio 350 2008. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson Cabrio 350 2008 and Larson SEi 180 Fish Series O/B 2005 from the same manufacturer?

Yes — both the Larson Cabrio 350 2008 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.

Detailed Evaluation & Buyer Recommendation

Larson Cabrio 350 2008 vs Larson SEi 180 Fish Series O/B 2005 — Same Brand, Different Boat

The Larson Cabrio 350 2008 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 330 hp, the Larson Cabrio 350 2008 has a 155-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 SEi 180 Fish Series O/B 2005 carries 29 gallons versus 23 gallons in the Larson Cabrio 350 2008. 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 Cabrio 350 2008 and its 330-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.
