Larson FX 1750 TL O/B 2013 vs Larson SEi 180 Ski Fish I/O 2008 — Same Brand, Different Boat

Matching a deep vee Larson FX 1750 TL O/B 2013 against a modified vee Larson SEi 180 Ski Fish I/O 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Larson FX 1750 TL O/B 2013 at 17,4 ft versus Larson SEi 180 Ski Fish I/O 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Larson FX 1750 TL O/B 2013 tips the scales at 1 972 lbs — 1 707 lbs more than the Larson SEi 180 Ski Fish I/O 2008 at 265 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 225 hp, the Larson SEi 180 Ski Fish I/O 2008 has a 135-hp advantage over the Larson FX 1750 TL O/B 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 22 gal and 23 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Larson SEi 180 Ski Fish I/O 2008 comes in at 1 lbs per hp versus 22 lbs per hp for the Larson FX 1750 TL O/B 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Larson SEi 180 Ski Fish I/O 2008 and its 225-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Larson FX 1750 TL O/B 2013 with its 90-hp rating is the more economical daily driver.

Larson FX 1750 TL O/B 2013 vs Larson SEi 180 Ski Fish I/O 2008 — Common Questions

Which is the larger boat — the Larson FX 1750 TL O/B 2013 or the Larson SEi 180 Ski Fish I/O 2008?
The Larson FX 1750 TL O/B 2013 is the longer of the two at 17,4 feet overall. The Larson SEi 180 Ski Fish I/O 2008 comes in at 17,0 feet, making it roughly 0,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Larson FX 1750 TL O/B 2013 or the Larson SEi 180 Ski Fish I/O 2008?
For trailering, the Larson SEi 180 Ski Fish I/O 2008 has the edge at 265 lbs dry weight versus 1 972 lbs for the Larson FX 1750 TL O/B 2013. 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 Ski Fish I/O 2008 is rated to a maximum of 225 hp, giving it the larger power ceiling. The Larson FX 1750 TL O/B 2013 tops out at 90 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 TL O/B 2013 is Coast Guard rated for 6 passengers, while the Larson SEi 180 Ski Fish I/O 2008 is certified for 6. 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 has the better power-to-weight ratio?
The Larson SEi 180 Ski Fish I/O 2008 has a better power-to-weight ratio at 1 lbs per hp compared to 22 lbs per hp for the Larson FX 1750 TL O/B 2013. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Larson FX 1750 TL O/B 2013 measures 96" wide, compared to 93" for the Larson SEi 180 Ski Fish I/O 2008. 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.
How do the fuel tanks compare on the Larson FX 1750 TL O/B 2013 and Larson SEi 180 Ski Fish I/O 2008?
Both boats carry similar fuel loads — 22 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.
Are the Larson FX 1750 TL O/B 2013 and Larson SEi 180 Ski Fish I/O 2008 from the same manufacturer?
Yes — both the Larson FX 1750 TL O/B 2013 and the Larson SEi 180 Ski Fish I/O 2008 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.
