Lighter than its competition yet built to withstand the rigours of saltwater operation. For go-fast boats and commercial offshore operations that operate in rough seas or need more speed. Great for deck, inflatable rigid hull, inshore fishing, multi-species fishing, offshore fishing and runabout cuddy boats and tritoons. |
The smooth, refined power of a 4.6-liter V-8 powerhead delivers exhilarating acceleration and top speed to run offshore with confidence, with generous displacement and robust design that provide uncompromising durability and reliability. The Mercury exclusive Advanced MidSection (AMS) and under-cowl noise management features set the standard for smooth, quiet marine propulsion |
