Global launch across a range of sectors for ground-breaking diesel outboard

Full-service support to build international awareness and assist with the unveiling of Cox’s CXO300 ̶ the world’s most powerful marine diesel outboard

Cox Powertrain has engineered the world’s highest-powered marine diesel outboard, following ten years of  development. With its roots in Formula 1 racing, and backing from the British Ministry of Defence, Cox’s innovative CXO300 is primarily targeted at the commercial, defence and superyacht markets. The firm initially approached Saltwater Stone in 2016, looking for assistance to create a “solid PR plan” to build momentum and brand awareness in the run up to the launch of its ground-breaking CXO300.

Mindful of the importance of good media coverage, Cox tasked Saltwater Stone with enabling and creating well-timed, considered copy to raise awareness and ensure the market was primed in anticipation of the release of the CXO300.

Cox Powertrain now enjoys a phenomenal level of brand awareness following our campaign to raise the firm’s profile and secure coverage in a range of international publications. Impressed by our work, as well as our knowledge of both the superyacht and commercial sectors, Cox quickly increased its initial brief by adding design services to our remit.

Our creative department collaborated with Cox’s marketing team to develop a series of key messaging concepts to run at various points across the year, as momentum built towards the launch of its first engine. These were rolled out across all platforms from print collateral and online advertising through to large-format graphics for exhibition stands and Cox’s new factory space.


Our work has included:

  • PR & media relations
  • Award nomination assistance
  • Brochure design & copy editing
  • Key messaging & concept development
  • Online & print advertisement design
  • Exhibition stand design
  • Wall graphics
  • Press event for product launch
  • Media buying

During this time, we also supported Cox at a range of global shows and exhibitions including the CXO300’s official industry launch, at Fort Lauderdale International Boat Show in October 2018, for which we organised a well-attended press event. Our long-term PR strategy has been backed up by an advertising campaign, managed by our media buyers, across a broad spectrum of publications.

Further work for Cox has included the production of content for online and print advertising, sales brochures, dealer and distributor documents, technical specifications, owners’ manuals and warranties. In addition, we have also created event banners and exhibition stands for Seawork, Monaco Yacht Show, Fort Lauderdale Boat Show, METSTRADE and the International Workboat Show.
