The Key Largo 174 2009 vs Key Largo 196 2006 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.
On paper these two are close siblings in the size department — Key Largo 174 2009 at 17,0 ft versus Key Largo 196 2006 at 19,0 ft. Weight tells a clearer story for trailering families: the Key Largo 174 2009 tips the scales at 1 375 lbs — 1 180 lbs more than the Key Largo 196 2006 at 195 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 150 hp, the Key Largo 196 2006 has a 60-hp advantage over the Key Largo 174 2009's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Key Largo 196 2006 carries 65 gallons versus 35 gallons in the Key Largo 174 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 Key Largo 196 2006 is rated for 7 passengers, while the Key Largo 174 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key Largo 196 2006 could be the deciding factor.
Bottom line: Choose the Key Largo 196 2006 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Key Largo 174 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
