300 Racing V8

Lighter than its competition yet built to withstand the rigors 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.
