Nitro 591 SC 2006 vs Nitro NX 898 DC 2005: Same Brand, Different Boat

The Nitro 591 SC 2006 vs Nitro NX 898 DC 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.

On paper these two are close siblings in the size department - Nitro 591 SC 2006 at 18,0 ft versus Nitro NX 898 DC 2005 at 20,0 ft. Weight tells a clearer story for trailering families: the Nitro NX 898 DC 2005 tips the scales at 1 790 lbs - 240 lbs less than the Nitro 591 SC 2006 at 1 550 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 225 hp, the Nitro NX 898 DC 2005 has a 25-hp advantage over the Nitro 591 SC 2006's 200-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 898 DC 2005 carries 50 gallons versus 43 gallons in the Nitro 591 SC 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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: Performance buyers should lean toward the Nitro NX 898 DC 2005 and its 225-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Nitro 591 SC 2006 with its 200-hp rating is the more economical daily driver.

Nitro 591 SC 2006 vs Nitro NX 898 DC 2005 - Common Questions

Which is the larger boat - the Nitro 591 SC 2006 or the Nitro NX 898 DC 2005?
The Nitro NX 898 DC 2005 is the longer of the two at 20,0 feet overall. The Nitro 591 SC 2006 comes in at 18,0 feet, making it roughly 2,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Nitro 591 SC 2006 or the Nitro NX 898 DC 2005?
For trailering, the Nitro 591 SC 2006 has the edge at 1 550 lbs dry weight versus 1 790 lbs for the Nitro NX 898 DC 2005. 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.
Which boat can handle a bigger outboard?
The Nitro NX 898 DC 2005 is rated to a maximum of 225 hp, giving it the larger power ceiling. The Nitro 591 SC 2006 tops out at 200 hp. Keep in mind that maximum ratings are just that - matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Nitro 591 SC 2006 is Coast Guard rated for 4 passengers, while the Nitro NX 898 DC 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.
Which boat is wider, and does it affect trailering?
The Nitro 591 SC 2006 measures 94" wide, compared to 93" for the Nitro NX 898 DC 2005. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank - the Nitro 591 SC 2006 or the Nitro NX 898 DC 2005?
The Nitro NX 898 DC 2005 has the bigger tank at 50 gallons, versus 43 gallons on the Nitro 591 SC 2006. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Nitro 591 SC 2006 and Nitro NX 898 DC 2005 from the same manufacturer?
Yes - both the Nitro 591 SC 2006 and the Nitro NX 898 DC 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.
