The Scout 151 Sportfish 2010 vs Scout 170 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 151 Sportfish 2010 at 14,6 ft versus Scout 170 Costa 2007 at 16,0 ft. At 6 lbs and 78 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 90 hp, the Scout 170 Costa 2007 has a 40-hp advantage over the Scout 151 Sportfish 2010's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 1 gal and 3 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Scout 151 Sportfish 2010 is rated for 6 passengers, while the Scout 170 Costa 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Scout 151 Sportfish 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Scout 151 Sportfish 2010 comes in at 0 lbs per hp versus 1 lbs per hp for the Scout 170 Costa 2007. 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.
Bottom line: Choose the Scout 151 Sportfish 2010 if your priority is putting more people on the water — it handles 6 passengers and at 14,6 ft it has the deck room to back that rating up comfortably. The Scout 170 Costa 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
