COX 300 V8 Diesel Outboard Engine NEW
Designed with sustainable innovation in mind, the V8 diesel outboard is a fuel efficient, eco-friendly outboard designed for maximum speed. Explore the careful engineering and flawless details our designers put into this powerful outboard motor.
Driving cleaner marine propulsion with sustainable design
At Cox Marine, sustainability is engineered into every outboard we build. From emissions compliance to alternative fuel compatibility and future-focused innovation, we are committed to reducing environmental impact without compromising performance.
Certified clean
The Cox Marine V8 diesel outboard is certified to the world’s leading emissions standards, including EPA Tier 3, IMO II, and RCD II. These certifications confirm our engines meet strict limits for NOx, hydrocarbons and particulate matter, supporting cleaner operations in regulated waterways and emissions-controlled zones around the globe.
Ready for renewable fuels
Cox outboards are fully compatible with HVO (Hydrotreated Vegetable Oil)-a sustainable diesel alternative derived from renewable feedstocks. When used with HVO, operators can significantly reduce lifecycle CO₂ emissions compared to conventional diesel, without requiring any engine modification.
Recent trials-including the 350 V8 launch demonstrations and the Pegasus programme-have proven the outboard’s robust performance on HVO, showcasing our commitment to cleaner fuel integration. This compatibility allows fleet operators, governments and private users to make an immediate switch to a more sustainable propulsion solution.
Powering future fuels
Cox Marine is actively investing in next-generation propulsion technologies, including hydrogen-diesel hybrid prototypes. These projects are already in development, supporting the marine industry’s transition to zero-emission alternatives over the long term. By combining hydrogen energy systems with our proven diesel platform, we aim to deliver scalable, flexible propulsion that meets future emissions targets and operational needs.
Build Features
Twin Turbo Engine
The V8 has twin-turbos that generate significantly more torque at lower RPM and maintan this power across engine speeds.
Vertical Crankshaft
The vertical design allows for efficient packaging and direct drive of the transmission, providing closer transom spacing for multiple installations.
Power Distribution Module
Equipped with self-resetting fuses , this module allows for active power management of the outboard power systems.
Electronic Controls & Steering
The Optimus Steering enhances control of your vessel. Compatibility with NMEA2000 makes it easy
to install on a wide range of vessels.
Power Tilt-Trim
Designed in-house, The V8’s PTT bracket is built to withstand the toughest sea conditions and has been put through extensive durability testing.
Universal Transom Bolting Pattern
Allows easy installation to a wide range of vessels, making re-powering easier than ever.
Transmission
The transmission has been specifically designed to withstand high torque, even when sea conditions are at their most challenging.
