Detailed Evaluation & Buyer Recommendation
Nitro 640 LX 2004 vs Nitro Z-7 Sport 2013 — Same Brand, Different Boat
The Nitro 640 LX 2004 vs Nitro Z-7 Sport 2013 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 150 hp, the Nitro Z-7 Sport 2013 has a 60-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. Both carry nearly identical fuel loads — 24 gal and 26 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Nitro Z-7 Sport 2013 is rated for 6 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 Z-7 Sport 2013 could be the deciding factor.
Bottom line: Choose the Nitro Z-7 Sport 2013 if your priority is putting more people on the water — it handles 6 passengers and at 19,4 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.
