Larson LX 620 O/B 2012 vs Larson Senza 186 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Larson LX 620 O/B 2012 or the Larson Senza 186 2005?

For trailering, the Larson Senza 186 2005 has the edge at 27 lbs dry weight versus 115 lbs for the Larson LX 620 O/B 2012.

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 LX 620 O/B 2012 has a documented max rating of 90 hp. Engine specifications for the Larson Senza 186 2005 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 LX 620 O/B 2012 is Coast Guard rated for 6 passengers, while the Larson Senza 186 2005 is certified for 9. 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 Senza 186 2005 measures 94" wide, compared to 88" for the Larson LX 620 O/B 2012. 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 LX 620 O/B 2012 or the Larson Senza 186 2005?

The Larson Senza 186 2005 has the bigger tank at 29 gallons, versus 19 gallons on the Larson LX 620 O/B 2012. That 10-gallon difference translates to roughly 30–50 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Larson LX 620 O/B 2012 and Larson Senza 186 2005 from the same manufacturer?

Yes — both the Larson LX 620 O/B 2012 and the Larson Senza 186 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 LX 620 O/B 2012 vs Larson Senza 186 2005 — Same Brand, Different Boat

The Larson LX 620 O/B 2012 vs Larson Senza 186 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 LX 620 O/B 2012 carries a rated maximum of 90 hp. Engine data for the Larson Senza 186 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Larson Senza 186 2005 carries 29 gallons versus 19 gallons in the Larson LX 620 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 Senza 186 2005 is rated for 9 passengers, while the Larson LX 620 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 Senza 186 2005 could be the deciding factor.

Bottom line: Choose the Larson Senza 186 2005 if your priority is putting more people on the water — it handles 9 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Larson LX 620 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.
