Matching a inflatable rigid Mercury DR490 2008 against a inflatable non rigid Mercury V-450 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Mercury DR490 2008 at 16,0 ft versus Mercury V-450 2008 at 14,0 ft. Weight tells a clearer story for trailering families: the Mercury DR490 2008 tips the scales at 469 lbs — 110 lbs more than the Mercury V-450 2008 at 359 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.
Both boats share a closely matched power ceiling — 80 hp for the Mercury DR490 2008 and 60 hp for the Mercury V-450 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Mercury DR490 2008 is rated for 8 passengers, while the Mercury V-450 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury DR490 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Mercury DR490 2008 comes in at 6 lbs per hp versus 6 lbs per hp for the Mercury V-450 2008. 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 DR490 2008 if your priority is putting more people on the water — it handles 8 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Mercury V-450 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
