The Starcraft Marine 1700 DC 2010 vs Starcraft Marine Nexstar 1900 I/O 2006 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 — Starcraft Marine 1700 DC 2010 at 16,9 ft versus Starcraft Marine Nexstar 1900 I/O 2006 at 19,0 ft. Weight tells a clearer story for trailering families: the Starcraft Marine 1700 DC 2010 tips the scales at 925 lbs — 904 lbs more than the Starcraft Marine Nexstar 1900 I/O 2006 at 21 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 350 hp, the Starcraft Marine Nexstar 1900 I/O 2006 has a 260-hp advantage over the Starcraft Marine 1700 DC 2010's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Nexstar 1900 I/O 2006 carries 45 gallons versus 23 gallons in the Starcraft Marine 1700 DC 2010. 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 Starcraft Marine 1700 DC 2010 is rated for 6 passengers, while the Starcraft Marine Nexstar 1900 I/O 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine 1700 DC 2010 could be the deciding factor.
Bottom line: Choose the Starcraft Marine 1700 DC 2010 if your priority is putting more people on the water — it handles 6 passengers and at 16,9 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Nexstar 1900 I/O 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
