Mercury 320 Ocean Runner White (Hypalon) 2006 vs Mercury 350 Amanzi 2008 — Same Brand, Different Boat

The Mercury 320 Ocean Runner White (Hypalon) 2006 vs Mercury 350 Amanzi 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 350 Amanzi 2008 measures 11,0 feet overall (2008), giving it roughly 10,0 additional feet of deck space compared to the Mercury 320 Ocean Runner White (Hypalon) 2006 at 1,0 feet (2006). Weight tells a clearer story for trailering families: the Mercury 320 Ocean Runner White (Hypalon) 2006 tips the scales at 182 lbs — 178 lbs more than the Mercury 350 Amanzi 2008 at 4 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 — 15 hp for the Mercury 320 Ocean Runner White (Hypalon) 2006 and 30 hp for the Mercury 350 Amanzi 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.

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 Mercury 350 Amanzi 2008 comes in at 0 lbs per hp versus 12 lbs per hp for the Mercury 320 Ocean Runner White (Hypalon) 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: The Mercury 350 Amanzi 2008 at 11,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Mercury 320 Ocean Runner White (Hypalon) 2006 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
