Nitro 640 LX 2004 vs Nitro 640 LX 2005 - Boat Spec Comparison

Q: Which is easier to trailer — the Nitro 640 LX 2004 or the Nitro 640 LX 2005?

For trailering, the Nitro 640 LX 2005 has the edge at 1 092 lbs dry weight versus 1 092 lbs for the Nitro 640 LX 2004. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

Q: How many people can each boat hold?

The Nitro 640 LX 2004 is Coast Guard rated for 4 passengers, while the Nitro 640 LX 2005 is certified for 4. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Nitro 640 LX 2004 and Nitro 640 LX 2005 share an 84 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: How do the fuel tanks compare on the Nitro 640 LX 2004 and Nitro 640 LX 2005?

Both boats carry similar fuel loads — 24 gallons and 24 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Q: Are the Nitro 640 LX 2004 and Nitro 640 LX 2005 from the same manufacturer?

Yes — both the Nitro 640 LX 2004 and the Nitro 640 LX 2005 are built by Nitro. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Nitro 640 LX 2004 vs Nitro 640 LX 2005 — Same Brand, Different Boat

The Nitro 640 LX 2004 vs Nitro 640 LX 2005 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.

Both boats share a closely matched power ceiling — 90 hp for the Nitro 640 LX 2004 and 90 hp for the Nitro 640 LX 2005. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Nitro 640 LX 2004 and Nitro 640 LX 2005 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
