Larson FX 1750 SC O/B 2012 vs Larson SEi 180 Fish Series O/B 2005: Same Brand, Different Boat

The Larson FX 1750 SC O/B 2012 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 175 hp, the Larson SEi 180 Fish Series O/B 2005 has a 25-hp advantage over the Larson FX 1750 SC O/B 2012's 150-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 FX 1750 SC O/B 2012. 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 SEi 180 Fish Series O/B 2005 is rated for 8 passengers, while the Larson FX 1750 SC O/B 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson SEi 180 Fish Series O/B 2005 could be the deciding factor.

Bottom line: Choose the Larson SEi 180 Fish Series O/B 2005 if your priority is putting more people on the water - it handles 8 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Larson FX 1750 SC O/B 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Larson FX 1750 SC O/B 2012 vs Larson SEi 180 Fish Series O/B 2005 - Common Questions

Which is easier to trailer - the Larson FX 1750 SC O/B 2012 or the Larson SEi 180 Fish Series O/B 2005?
For trailering, the Larson FX 1750 SC O/B 2012 has the edge at 1 600 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.
Which boat can handle a bigger outboard?
The Larson SEi 180 Fish Series O/B 2005 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Larson FX 1750 SC O/B 2012 tops out at 150 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.
How many people can each boat hold?
The Larson FX 1750 SC O/B 2012 is Coast Guard rated for 6 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.
Which boat is wider, and does it affect trailering?
The Larson FX 1750 SC O/B 2012 measures 96" 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.
Which boat has the larger fuel tank - the Larson FX 1750 SC O/B 2012 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 FX 1750 SC O/B 2012. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Larson FX 1750 SC O/B 2012 and Larson SEi 180 Fish Series O/B 2005 from the same manufacturer?
Yes - both the Larson FX 1750 SC O/B 2012 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.
