After a decade of development, British diesel-engine company Cox Powertrain has introduced the CXO300 300 hp diesel outboard. The 4.4L four-stroke V-8 offers at least a 25 percent better range than a gasoline outboard, Cox says, and the engine is designed to last up to three times longer with extended service intervals and reduced haul-out costs. The 300 will be offered in three shaft lengths: 25, 30 and 35 inches. It weighs 827 pounds and is expected to cost $50,000.
