Cox Marine sets new speed records with sustainable fuel

Using 100 per cent sustainable fuel, outboard manufacturer Cox Marine has set two new speed records (subject to ratification) at the recent 51st annual Coniston Powerboat Records Week, held at Coniston Water in the Lake District.

The records*, for fastest Diesel Outboard British Speed and fastest Diesel Outboard World Speed, saw skipper Adam Brown reach 67.95mph on Coniston Water with a CXO300 engine. This is over five mph faster than Cox Marine’s previous 2022 record of 62.84mph, also set by Brown.

The competing vessel, a 21ft Hallett Vector boat named Pegasus, and the team’s supporting vehicles were powered by bespoke biodiesel blends from Coryton’s Sustain Racing range. Made of 100 per cent second-generation biowaste, mainly wood waste, the biodiesels are said to use carbon recycled from the atmosphere via plants rather than releasing new carbon.

Cox Marine says that the Sustain Racing fuels offer a 90 per cent reduction in greenhouse gas emissions compared to traditional fossil fuels, and that using the fuels has enabled it to deliver an estimated saving of 470kg of CO2 compared to running on conventional diesel.

“It’s fantastic to have been able to return to the spiritual home of British water speed records and better our records with the support of Coryton,” says Cox Marine, technical director, James Eatwell.

“We’d like to thank both Coniston Record Week and the Lake District National Park for their help and assistance in making this happen. Our team at Cox Marine has done some fantastic work in demonstrating how much further we can push the performance of our outboard technology while still being able to prove that performance does not need to be at the expense of fuel efficiency or CO2 emissions.

“The amalgamation of the inherent fuel efficiency of the CXO300 engine with Coryton’s low-carbon Sustain fuel has allowed us to demonstrate a record-breaking low-carbon combination at Coniston.”

David Richardson, business development director at Coryton, comments: “We’re delighted to have supported Cox Marine in what is a fantastic achievement for the team. Coniston Water is a stunning location, and it’s great that we’ve been able to honour this setting with the cleaner, sustainable fuel it deserves.

“From the waters of Coniston to the deserts of the Dakar Rally, we continue to prove how well sustainable fuels can perform whilst providing vital carbon savings for our racing partners. We can only hope that the results we’re recording will go on to inspire others and help secure more investment and interest for this solution long into the future.”
