Buy OXE 300 HP Diesel Outboard Engine Online
For boaters in the United States and Europe seeking maximum efficiency and power, the OXE 300 HP outboard diesel engine is the definitive choice. Engineered with a 6-cylinder bi-turbo diesel powerhead derived from the automotive industry, this engine produces 300 HP at 4200-4400 RPM and an outstanding 945Nm of torque at the propeller shaft.
Whether you operate a commercial workboat, patrol vessel, or large recreational craft, the OXE300 transforms your on-water experience. Diesel fuel provides superior energy density, allowing you to carry heavier loads while consuming 46% less fuel than a modern gasoline outboard. This translates into up to 87% greater range – a game-changer for offshore operators in Florida, the North Sea, or the Mediterranean.
Environmental compliance is built in. Compared to gasoline outboards, the OXE300 reduces CO₂ emissions by more than 35.5% . When running on BioDiesel, net CO₂ drops by up to 94.2% . CO emissions are slashed from 620g/l (unregulated gasoline) to just 8.36g/l (EPA Tier III). HC + NOx emissions are reduced by nearly 70%.
The closed cooling circuit, hydraulic multi-friction plate clutch, and CANbus electro-hydraulic shift ensure smooth, reliable operation. Choose hydraulic steering, Electronic Power Steering, or joystick control. Leg lengths of 25” or 33” fit most transoms.
