When two boats share the same hull type — in this case both the Key Largo 168 2010 and the Key Largo 174 2009 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Key Largo 168 2010 at 16,0 ft versus Key Largo 174 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Key Largo 174 2009 tips the scales at 1 375 lbs — 1 250 lbs less than the Key Largo 168 2010 at 125 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.

Both boats share a closely matched power ceiling — 75 hp for the Key Largo 168 2010 and 90 hp for the Key Largo 174 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Key Largo 174 2009 carries 35 gallons versus 23 gallons in the Key Largo 168 2010. 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 174 2009 is rated for 5 passengers, while the Key Largo 168 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key Largo 174 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Key Largo 168 2010 comes in at 2 lbs per hp versus 15 lbs per hp for the Key Largo 174 2009. 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.
