There are worse places to spend a day testing…

This incredible shot was captured by our Test and Development crew while putting the AX300 Diesel outboard through its paces on the water in Dubai.

Behind the view is another day of accumulating hours, gathering data and testing performance in the heat, humidity and high salinity of the UAE.

For professional marine operators, performance is about more than speed. It is about control under load, fuel used across a long working day and keeping the vessel available when it is needed.

The AX300 Diesel Outboard brings together a 3.0L V6 turbo diesel engine, contra-rotating dual propellers and our patented AXIS integrated steering system to deliver high torque, precise control and confident manoeuvring.

With up to 50% lower fuel consumption in commercial duty cycles and maintenance designed to reduce time off the water, the AX300 has been engineered around the measure that matters most: uptime.

What matters most to your operation: fuel efficiency, torque, control or ease of maintenance?

This wasn’t part of the day’s testing…
While underway, the crew encountered a disabled sailboat and helped tow it safely back into the marina, putting the twin AX300 Diesel outboard set-up to work in an unexpected real-world situation.

Every mission matters 👌

Another step forward in our global validation programme. 🇺🇸

Our upgraded twin AX300 Diesel outboards are now installed on a commercial barge boat in the United States, ready for the next phase of testing in real working conditions.
