"Diesel Outboard

WITHOUT COMPROMISE"

All the benefits of diesel.
None of the compromise.

The CXO300 diesel outboard engine truly breaks new ground, delivering the same uncompromising power, performance, and durability you’d normally only associate with a diesel inboard engine.

At the same time, it offers all the convenience and flexibility of an outboards and is similar in size and weight to petrol alternatives, as well as more efficient. Which means it is designed to be compliant with the toughest emissions standards in the world including IMO, EPA and EU emissions levels.

Channeling best-in-class automotive manufacturing and the latest in intelligent tooling and scanning, the CXO300 diesel outboard engine sets the standard for world-leading quality and robustness. This fusion drives us forward in a relentless pursuit of revolutionary technology.

THE NEW STANDARDS

IN SERVICE

Our service and support meet the same uncompromisingly high standards as our engineering and performance. The CXO300 comes with a 1,500 hour warranty as standard, with an optional service package also available.

 

COX 300 HP: DESIGNED AND BUILT IN BRITAIN

ENVIRONMENT

 

The use of highly refined, modern automotive-based engine technology significantly reduces the fuel consumption and provides for industry leading emission levels and subsequent minimized impact on the environment. The emission levels are approved by EPA TIER III, IMO TIER II (MARPOL VI TIER 2) and RCD.

SAFETY FIRST

 

Diesel is a less flammable fuel and therefore safer to work with in hazardous environments. Robust design and quick shift capability leads to safe operation in fierce conditions. The COX Diesel is designed to be safe in any environment.

GREAT RANGE

 

Due to significantly lower fuel consumption than a comparable modern outboard the COX Diesel offers the market an unprecedented range. Enabling users to go further and refilling from other vessels or marine based platform.
