The Nitro 901 CDX SC 2006 vs Nitro Bay 1800 2004 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 200 hp, the Nitro 901 CDX SC 2006 has a 110-hp advantage over the Nitro Bay 1800 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 901 CDX SC 2006 carries 57 gallons versus 15 gallons in the Nitro Bay 1800 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 Bay 1800 2004 is rated for 5 passengers, while the Nitro 901 CDX SC 2006 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nitro Bay 1800 2004 could be the deciding factor.
