The Scout 151 Series 2012 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.
Size is the most obvious dividing line here. The Scout 190 Costa 2007 measures 19,0 feet overall (2007), giving it roughly 4,4 additional feet of deck space compared to the Scout 151 Series 2012 at 14,6 feet (2012). At 6 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.
The power gap is worth calling out. Rated to 115 hp, the Scout 190 Costa 2007 has a 65-hp advantage over the Scout 151 Series 2012's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Scout 190 Costa 2007 carries 45 gallons versus 1 gallons in the Scout 151 Series 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 Scout 190 Costa 2007 is rated for 5 passengers, while the Scout 151 Series 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 190 Costa 2007 could be the deciding factor.
Bottom line: Choose the Scout 190 Costa 2007 if your priority is putting more people on the water — it handles 5 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Scout 151 Series 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
