The Mercury 320 Ocean Runner White (Hypalon) 2006 vs Mercury 350 Amanzi Hypalon 2012 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 Hypalon 2012 measures 11,5 feet overall (2012), giving it roughly 10,5 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 350 Amanzi Hypalon 2012 tips the scales at 675 lbs — 493 lbs less than the Mercury 320 Ocean Runner White (Hypalon) 2006 at 182 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 40 hp, the Mercury 350 Amanzi Hypalon 2012 has a 25-hp advantage over the Mercury 320 Ocean Runner White (Hypalon) 2006's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 320 Ocean Runner White (Hypalon) 2006 comes in at 12 lbs per hp versus 17 lbs per hp for the Mercury 350 Amanzi Hypalon 2012. 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.
