Built to outperform traditional gasoline engines, the OXE 300 provides 680 Nm (502 ft-lb) of torque at just 1750 rpm, and over 500 Nm (369 ft-lb) even at 1000 rpm — giving you the pulling strength and acceleration power you need in the harshest marine environments.

Performance and Efficiency

1. Exceptional Power and Torque
The OXE 300 features a 6-cylinder, bi-turbo diesel engine that provides strong, consistent power across the entire RPM range. Its torque-rich design ensures quick acceleration and powerful bollard pull for heavy-duty marine applications.

2. Unrivaled Fuel Economy
With up to 46% lower fuel consumption compared to modern gasoline outboards, the OXE 300 Diesel extends your range and reduces operating costs. Its efficient diesel powerhead allows operators to refuel from larger vessels or marine platforms, maximizing uptime.

3. Long-Range Capability
Thanks to diesel’s higher energy density, the OXE 300 offers an 87% longer operating range than equivalent petrol engines — ideal for long-distance transport, patrol, or workboat operations.

Power and Versatility

The OXE 300 HP Jet-Tech is both a workhorse and a high-speed marine solution. Its modular design and robust transmission system deliver exceptional flexibility for demanding applications. Whether you’re hauling, patrolling, or cruising, the OXE 300 delivers dependable, high-performance propulsion.

Environmental Advantages

Reduced CO₂ Emissions
By consuming up to 46% less fuel, the OXE 300 reduces CO₂ emissions by more than 35% compared to gasoline outboards. When fueled with BioDiesel, emissions can be reduced by up to 94%, making it one of the cleanest high-horsepower outboards on the market.

Reduced CO, HC, and NOx Emissions
The OXE 300 benefits from automotive-grade emission standards (EPA Tier III), cutting carbon monoxide emissions by over 98% and HC/NOx emissions by 69% compared to non-regulated gasoline engines. Cleaner operation means less environmental impact and longer compliance life.

Why Jet-Tech Propulsion?

Advanced Waterjet Technology
The Jet-Tech system is purpose-built to handle the high torque of the OXE Diesel outboard range. It converts 100% of engine horsepower into waterjet thrust for superior efficiency.

Shaft-Free Operation
With a forward-facing impeller, Jet-Tech propulsion achieves performance equal to or better than traditional propellers — without the drag or risk of shaft damage.

Plug-and-Play Integration
The Jet-Tech unit is a direct bolt-on, plug-and-play replacement for the OXE Diesel lower unit, ensuring effortless installation and compatibility.

Enhanced Safety
By replacing the propeller with a waterjet, Jet-Tech eliminates the risk of prop strikes, making it safer for swimmers, marine life, and shallow-water operations.
