The Mercury 270 Dinghy PVC 2013 vs Mercury 340 Ocean Runner White (Hypalon) 2006 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 — Mercury 270 Dinghy PVC 2013 at 8,8 ft versus Mercury 340 Ocean Runner White (Hypalon) 2006 at 11,0 ft. Weight tells a clearer story for trailering families: the Mercury 340 Ocean Runner White (Hypalon) 2006 tips the scales at 185 lbs — 119 lbs less than the Mercury 270 Dinghy PVC 2013 at 66 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 — 5 hp for the Mercury 270 Dinghy PVC 2013 and 15 hp for the Mercury 340 Ocean Runner White (Hypalon) 2006. 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 340 Ocean Runner White (Hypalon) 2006 is rated for 5 passengers, while the Mercury 270 Dinghy PVC 2013 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury 340 Ocean Runner White (Hypalon) 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 340 Ocean Runner White (Hypalon) 2006 comes in at 12 lbs per hp versus 13 lbs per hp for the Mercury 270 Dinghy PVC 2013. 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 340 Ocean Runner White (Hypalon) 2006 if your priority is putting more people on the water — it handles 5 passengers and at 11,0 ft it has the deck room to back that rating up comfortably. The Mercury 270 Dinghy PVC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
