When two boats share the same hull type — in this case both the Scout 175 Dorado 2009 and the Scout 187 Sportfish 2012 are modified 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 — Scout 175 Dorado 2009 at 17,0 ft versus Scout 187 Sportfish 2012 at 18,4 ft. At 124 lbs and 151 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 — 130 hp for the Scout 175 Dorado 2009 and 150 hp for the Scout 187 Sportfish 2012. 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 187 Sportfish 2012 carries 45 gallons versus 32 gallons in the Scout 175 Dorado 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 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.
Bottom line: Performance buyers should lean toward the Scout 187 Sportfish 2012 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Scout 175 Dorado 2009 with its 130-hp rating is the more economical daily driver.
