The Nitro NX 750 SC 2006 vs Nitro NX 898 SC 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.
Size is the most obvious dividing line here. The Nitro NX 750 SC 2006 measures 17,0 feet overall (2006), giving it roughly 15,0 additional feet of deck space compared to the Nitro NX 898 SC 2005 at 2,0 feet (2005). At 135 lbs and 176 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 225 hp, the Nitro NX 898 SC 2005 has a 90-hp advantage over the Nitro NX 750 SC 2006's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 5 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Nitro NX 750 SC 2006 is rated for 5 passengers, while the Nitro NX 898 SC 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nitro NX 750 SC 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Nitro NX 898 SC 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Nitro NX 750 SC 2006. 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: Choose the Nitro NX 750 SC 2006 if your priority is putting more people on the water — it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Nitro NX 898 SC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
