Nitro 591 SC 2006 vs Nitro 750 2007 — Same Brand, Different Boat

The Nitro 591 SC 2006 vs Nitro 750 2007 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 750 2007 at 17,0 ft. At 155 lbs and 135 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 200 hp, the Nitro 591 SC 2006 has a 110-hp advantage over the Nitro 750 2007'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 591 SC 2006 carries 43 gallons versus 3 gallons in the Nitro 750 2007. 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Nitro 591 SC 2006 comes in at 1 lbs per hp versus 2 lbs per hp for the Nitro 750 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Nitro 591 SC 2006 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Nitro 750 2007 with its 90-hp rating is the more economical daily driver.

Nitro 591 SC 2006 vs Nitro 750 2007 — Common Questions

Which is the larger boat — the Nitro 591 SC 2006 or the Nitro 750 2007?
The Nitro 591 SC 2006 is the longer of the two at 18,0 feet overall. The Nitro 750 2007 comes in at 17,0 feet, making it roughly 1,0 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 750 2007?
For trailering, the Nitro 750 2007 has the edge at 135 lbs dry weight versus 155 lbs for the Nitro 591 SC 2006. 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 591 SC 2006 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Nitro 750 2007 tops out at 90 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 750 2007 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 has the better power-to-weight ratio?
The Nitro 591 SC 2006 has a better power-to-weight ratio at 1 lbs per hp compared to 2 lbs per hp for the Nitro 750 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
What do the trailers weigh for the Nitro 591 SC 2006 and Nitro 750 2007?
The trailer for the Nitro 591 SC 2006 is listed at 3,180 lbs and the Nitro 750 2007 trailer at 2,325 lbs. Always add trailer weight to the boat's dry weight when checking your tow vehicle's gross trailer weight rating.
Which boat is wider, and does it affect trailering?
The Nitro 591 SC 2006 measures 94" wide, compared to 86" for the Nitro 750 2007. 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 750 2007?
The Nitro 591 SC 2006 has the bigger tank at 43 gallons, versus 3 gallons on the Nitro 750 2007. That 40-gallon difference translates to roughly 120–200 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Nitro 591 SC 2006 and Nitro 750 2007 from the same manufacturer?
Yes — both the Nitro 591 SC 2006 and the Nitro 750 2007 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.
