Larson 180 Sport 2009 vs Larson SEi 190 I/O SF 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson 180 Sport 2009 or the Larson SEi 190 I/O SF 2004?

For trailering, the Larson SEi 190 I/O SF 2004 has the edge at 265 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 190 I/O SF 2004 has a documented max rating of 300 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 190 I/O SF 2004 is certified for 5. 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 190 I/O SF 2004 measures 94" 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 190 I/O SF 2004?

The Larson SEi 190 I/O SF 2004 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 190 I/O SF 2004 from the same manufacturer?

Yes — both the Larson 180 Sport 2009 and the Larson SEi 190 I/O SF 2004 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 190 I/O SF 2004 — Same Brand, Different Boat

The Larson 180 Sport 2009 vs Larson SEi 190 I/O SF 2004 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 190 I/O SF 2004 tops out at 300 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 190 I/O SF 2004 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.

For family outings this is probably the sharpest distinction between the two. The Larson 180 Sport 2009 is rated for 8 passengers, while the Larson SEi 190 I/O SF 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson 180 Sport 2009 could be the deciding factor.

Bottom line: Choose the Larson 180 Sport 2009 if your priority is putting more people on the water — it handles 8 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Larson SEi 190 I/O SF 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
