Larson 180 Sport 2009 vs Larson SEi 180 Fish Series O/B 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson 180 Sport 2009 or the Larson SEi 180 Fish Series O/B 2005?

For trailering, the Larson SEi 180 Fish Series O/B 2005 has the edge at 1 785 lbs dry weight versus 2 375 lbs for the Larson 180 Sport 2009. 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: What is the maximum horsepower rating for these boats?

The Larson SEi 180 Fish Series O/B 2005 has a documented max rating of 175 hp. Engine specifications for the Larson 180 Sport 2009 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Larson 180 Sport 2009 is Coast Guard rated for 8 passengers, while the Larson SEi 180 Fish Series O/B 2005 is certified for 8. 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 is wider, and does it affect trailering?

The Larson SEi 180 Fish Series O/B 2005 measures 93" wide, compared to 88" for the Larson 180 Sport 2009. 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 180 Sport 2009 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 180 Sport 2009. 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 180 Sport 2009 and Larson SEi 180 Fish Series O/B 2005 from the same manufacturer?

Yes — both the Larson 180 Sport 2009 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 180 Sport 2009 vs Larson SEi 180 Fish Series O/B 2005 — Same Brand, Different Boat

The Larson 180 Sport 2009 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 180 Sport 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Larson SEi 180 Fish Series O/B 2005 carries 29 gallons versus 23 gallons in the Larson 180 Sport 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Larson 180 Sport 2009 and Larson SEi 180 Fish Series O/B 2005 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
