We specialise in custom bespoke engineering for advanced propulsion systems, integrating engines from leading manufacturers, including Yanmar, Mercury, Cox Marine, Hybrid Marine International, and Shire. These systems are selected for their proven reliability and durability in the most demanding marine environments—where performance is critical and failure is not an option.

Operating from our Bicester facility, we design, develop, test, and install bespoke solutions for defence, emergency response, and law enforcement sectors, including the MoD, rescue, and police services.

With extensive engineering expertise, fully equipped in-house facilities, and exclusive innovations such as FAST PIRS® (Post Immersion Restart System)—enabling rapid engine restart following submersion—as well as low-signature propulsion technologies, we deliver cutting-edge solutions tailored to operational needs.

We work in close partnership with our clients to provide complete turnkey solutions, covering everything from research and development through to production, installation, support, training, and full engine rebuild services.

In addition, we supply over 30,000 marine products from more than 20 trusted brands, supporting all aspects of vessel protection, maintenance, electronics, and onboard safety.
