The Mercury 240 Roll-Up 2007 vs Mercury PT520 2008 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 Mercury PT520 2008 measures 17,0 feet overall (2008), giving it roughly 10,0 additional feet of deck space compared to the Mercury 240 Roll-Up 2007 at 7,0 feet (2007). Weight tells a clearer story for trailering families: the Mercury PT520 2008 tips the scales at 661 lbs — 599 lbs less than the Mercury 240 Roll-Up 2007 at 62 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 100 hp, the Mercury PT520 2008 has a 95-hp advantage over the Mercury 240 Roll-Up 2007's 5-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Mercury PT520 2008 is rated for 9 passengers, while the Mercury 240 Roll-Up 2007 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury PT520 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Mercury PT520 2008 comes in at 7 lbs per hp versus 12 lbs per hp for the Mercury 240 Roll-Up 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: Choose the Mercury PT520 2008 if your priority is putting more people on the water — it handles 9 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Mercury 240 Roll-Up 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
