The Scout 170 Costa 2009 vs Scout 190 Costa 2007 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 — Scout 170 Costa 2009 at 16,0 ft versus Scout 190 Costa 2007 at 19,0 ft. At 98 lbs and 12 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 115 hp for the Scout 170 Costa 2009 and 115 hp for the Scout 190 Costa 2007. 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 Scout 190 Costa 2007 carries 45 gallons versus 3 gallons in the Scout 170 Costa 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 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.
Bottom line: The Scout 190 Costa 2007 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Scout 170 Costa 2009 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
