UK engine maker achieves diesel outboard World Speed Record of 62.27mph.
The Cox Marine team and their vessel Pegasus surpassed their own three prior speed records to clinch a coveted World Record title for the world’s fastest diesel outboard.
Participating in this year’s 50th Anniversary Speed Week, held at Coniston Water in Cumbria in the UK, Cox Marine says it achieved the industry’s first-ever diesel outboard World Speed Record.
The Cox Marine team and their vessel Pegasus surpassed their own three prior speed records, recorded earlier this week, to clinch a coveted World Record title for the world’s fastest diesel outboard achieving an average speed of 62.27mph.
Measured across a kilometre-long course requiring a flying start, Pegasus, a 21ft Hallett Vector piloted by powerboat racer Adam Brown, was required to travel the course’s distances in both directions, within an hour to minimise any potential wind advantage. With official Water Speed Record timekeepers’ oversight, both time and the speed in both directions, are recorded and then averaged over the two runs constituting the final speed.
Returning to shore following the successful completion of the second run, Brown said: “While there will, of course, be faster boats out on the lake today, it’s a great honour to be able to set a new record. There may be future diesel outboard powered record attempts, but Cox Marine will always be the first. 62.27mph is a great time for a 300hp engine which is straight off the production line and not having been optimised for powerboat racing.
With initial runs being carried out on regular diesel, before switching over to HVO100 fuel Cox Marine’s internal testing, carried out lakeside during the runs, have shown a 28% fuel saving over an equivalent 300hp gasoline engine and net CO2 emissions reductions of 92%.
The Coniston debut marks the company’s official support of HVO fuel use in their outboards without impacting warrantees, service schedules or requiring any modification to the engine.
