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

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

For trailering, the Larson SEi 180 I/O 2004 has the edge at 2 365 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 I/O 2004 has a documented max rating of 150 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 I/O 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 180 I/O 2004 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: How do the fuel tanks compare on the Larson 180 Sport 2009 and Larson SEi 180 I/O 2004?

Both boats carry similar fuel loads — 23 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Larson 180 Sport 2009 and Larson SEi 180 I/O 2004 from the same manufacturer?

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

The Larson 180 Sport 2009 vs Larson SEi 180 I/O 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 180 I/O 2004 tops out at 150 hp. Engine specs for the Larson 180 Sport 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.

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 180 I/O 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 180 I/O 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.
