Cox Marine Diesel Outboards, the only diesel outboard engines built for marine purposes.
Why does this matter? Imagine taking an automotive block, turning it on its side, and using it to power a marine vessel. You can imagine the host of problems that would cause. But the Cox diesel outboard is the only outboard built specifically for marine applications, meaning the engine was designed by Cox, from the ground up, to power marine vessels. Not only does this make it more efficient and reliable, but it also makes servicing the engine much easier. In other words, this engine is tailored to meet the unique requirements and challenges of powering boats and watercraft.
Some key points:
Vertical Crankshaft Design: The use of a vertical crankshaft is a notable feature. This design choice can contribute to better fuel efficiency and performance in a marine setting. It might also have advantages in engine balance and weight distribution.
Fuel Efficiency: The Cox diesel outboard engine offers 30 percent better fuel efficiency compared to a 300-hp gasoline outboard. This is a significant improvement in fuel consumption, which can translate into cost savings and reduced environmental impact.
Extended Service Life: Another important aspect is the longer service life which is three times greater than the average outboard. This can be a substantial benefit for boat owners, as it reduces the frequency of maintenance, repairs, and engine replacement, further contributing to cost savings.
Total Cost of Ownership (TCO) Savings: The combination of better fuel efficiency and an extended service life leads to exceptional total cost of ownership savings. TCO includes not only the initial purchase price but also operating costs over the life span of the engine. By reducing fuel consumption and maintenance needs, Cox Marine’s diesel outboard engine aims to provide boat owners with a more cost-effective solution in the long run.
The vision of the Cox Marine diesel outboard began in 1966, when Charles Good was 20 years old aboard his mom’s wooden sailboard, anchored off Greece’s Ionian Island. He was decanting gasoline into a small container when he spilled fuel on the deck of the boat and the gasoline erupted into flames after it contacted a nearby gas-powered refrigerator. This left Good with the lasting impression that there must be a way to develop an outboard engine using diesel fuel, which is significantly less flammable than gasoline.
Fast-forward to 2008, when a project that David Cox was working on hit Good’s desk. Good took the plans to the engineering firm of Ricardo PLC, who are intrigued with the safety and fuel efficiency of the diesel outboard engine. Their intrigue was enough to commit Good and his investor group to financially back the development of Cox’s diesel into the powerhead of an outboard engine.
In 2010, Cox Marine started to deliver a revolutionary new concept, an outboard that would be the first stop on the journey to power the future of the global marine industry through sustainable innovation. Since then, with the help of private investment, Cox Marine has brought a dream to reality with the delivery of the V8 family that began with the 300-horsepower engine in 2022 followed by the release of the 350-horse powered engine in 2024.
Cox Marine introduced the world’s first and only 350 hp diesel outboard at the Miami Boat show in February of 2024. Not only does the 350-offer additional horsepower, but the increased torque of 1052 Nm (776 ft-lb) gives you the power to embark on longer adventures and cruise with confidence. With the COX Marine diesel engine, you can spend more time enjoying the water and less time worrying about refueling.
