Detailed Evaluation & Buyer Recommendation
Nitro 640 LX 2004 vs Nitro NX 750 SC 2006: Same Brand, Different Boat
The Nitro 640 LX 2004 vs Nitro NX 750 SC 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.
The power gap is worth calling out. Rated to 135 hp, the Nitro NX 750 SC 2006 has a 45-hp advantage over the Nitro 640 LX 2004'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 Nitro NX 750 SC 2006 carries 30 gallons versus 24 gallons in the Nitro 640 LX 2004. 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 Nitro NX 750 SC 2006 is rated for 5 passengers, while the Nitro 640 LX 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nitro NX 750 SC 2006 could be the deciding factor.
Bottom line: Choose the Nitro NX 750 SC 2006 if your priority is putting more people on the water - it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Nitro 640 LX 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
