The Scout 170 Costa 2007 vs Scout 205 Dorado 2008 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 2007 at 16,0 ft versus Scout 205 Dorado 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Scout 205 Dorado 2008 tips the scales at 192 lbs — 114 lbs less than the Scout 170 Costa 2007 at 78 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.
The power gap is worth calling out. Rated to 225 hp, the Scout 205 Dorado 2008 has a 135-hp advantage over the Scout 170 Costa 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 6 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Scout 205 Dorado 2008 is rated for 8 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 205 Dorado 2008 could be the deciding factor.
Bottom line: Choose the Scout 205 Dorado 2008 if your priority is putting more people on the water — it handles 8 passengers and at 19,0 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.
