Cox CXO300 diesel outboard engine gains US EPA emissions tick
The world’s most powerful diesel outboard engine, the Cox CXO300, is cleared for sale in one of the world’s biggest marketsDiesel outboard engine maker Cox Powertrain has passed tough US emissions standards that will allow its fuel-efficient products to go on sale in North America.
The US EPA Tier 3 approval applies to both commercial and recreational use, Cox said in a statement on its website announcing the landmark certification.
“As the CXO300 is a new design built for purpose, Cox has had to work with the EPA to go through a rigorous testing process for an OEM engine,” Cox said.

“The main role of the EPA is to protect human health and to safeguard the natural environment.
“Emissions regulations are constantly evolving so it was imperative that Cox designed a clean-burning engine to ensure its ability to meet current and evolving emission standards for the CXO300 to receive approval from the agency.
The British designed and built 300hp twin-turbo V8 engine produces a thumping 650Nm, with peak torque arriving much lower in the rev range compared with an equivalent four-stroke petrol outboard engine.
Lower carbon footprint
Cox said the diesel outboard engine also had a much lower carbon footprint than an equivalent petrol-fuelled outboard engine.
“So far, those who have joined us on sea trials have commented favourably how quiet, smooth, and clean the engine is,” Cox global sales director Joel Reid said.
Production of the Cox CXO300 started in May at the company’s UK headquarters. The first outboards destined for the US market are due to be shipped in June.
The Cox CXO300 will be distributed in Australia via Melbourne-based Power Equipment, which is also the official distributor for Yanmar marine engines.
