Detailed Evaluation & Buyer Recommendation
Nitro 640 LX 2004 vs Nitro Z18 Pro Package w/150HP Pro-XS 2022 — Same Brand, Different Boat
The Nitro 640 LX 2004 vs Nitro Z18 Pro Package w/150HP Pro-XS 2022 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 Nitro 640 LX 2004 carries a rated maximum of 90 hp. Engine data for the Nitro Z18 Pro Package w/150HP Pro-XS 2022 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Nitro Z18 Pro Package w/150HP Pro-XS 2022 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 Z18 Pro Package w/150HP Pro-XS 2022 could be the deciding factor.
Bottom line: Choose the Nitro Z18 Pro Package w/150HP Pro-XS 2022 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 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.
