Operational Benefits

Accessible service points and longer service intervals lead to lower maintenance costs and longer operation times. Long service intervals result in life cycle costs that are kept at a minimum whilst time on the water remains high. The combination of the modern automotive diesel engine and the OXE Marine patented belt transmission provide the OXE Diesel with unique benefits for durability and increased range, optimized to reduce life cycle costs.


Endurance - Low Maintenance Cost and Longer Service Life

The OXE Diesel combines an efficient transmission and a slimmed down underwater design. Our solution merges improved hydrodynamic properties with the benefits of a horizontally mounted modern diesel engine from the automotive industry. In short, the OXE Diesel is designed to last.

All service points are placed above the waterline. The heavy-duty gearbox is built to withstand multiple crash-stops to endure commercial usage.

Easily accessible service points and a modular design create a user-friendly product. The reliable automotive powerhead keeps costs of maintenance and spare parts low. Longer service intervals ensure fewer disruptions in engine usage, increasing operational profitability and productivity. In short, the OXE Diesel has been optimized to reduce life cycle cost.

The service intervals of 200 hours for routine service and 800 hours for the extended service is a testament to the reliability of the system. A dealer service is recommended after each 2000 hours in use. In comparison with other outboards, which typically should last more than 380 hours, in line with the CE regulations, the OXE Diesel far surpasses that.

Great Maneuverability

The Low Speed Control (LSC) and Quick Shift Capability (QSC) provide a refined and smooth maneuverability. The high torque of the engine also ensures there is enough power for maneuvering under high loads and/or low speeds, even under 4 knots.

Power and Versatility with Adjustable Gear Ratios

The common rail turbo-charged diesel engine provides high efficiency and torque. This results in powerful thrust and acceleration, with the capacity to carry heavy loads.

Fast interchangeable gear ratios allow for specific performance requirements and the powerful torque of the OXE Diesel engine to be utilized in the best possible way. This increases the versatility of the OXE Diesel further as it opens up for a smorgasbord of applications.

Long Range and Great Fuel Economy

Due to a significantly lower fuel consumption than a leisure outboard, the OXE Diesel offers the user unprecedented range. The fact that OXE Diesel run on diesel gives the user the ability to refuel from larger diesel-powered vessels or marine-based platforms that further increases the versatility. This greatly increases operational runtimes for operators who predominantly uses diesel as the mail fuel. The OXE Diesel also has great fuel economy and uses 40% less fuel than a modern, leisure, gasoline outboard.


To meet commercial customers’ demands, the OXE Diesel was designed with ease of maintenance and service in mind. All service access points for daily maintenance checks are located in the front of the engine. This makes service and maintenance as easy and straight forward as possible, even in the harshest of conditions. The modular design makes it possible to approach service and maintenance in a flexible way, as entire modules can be swapped out and serviced on land, hence keeping operational runtimes up. It is a fact that user friendliness and easily accessible service points increase the likelihood for well-maintained products.


As the OXE Diesel is designed as an outboard package with standardized transom mounts, it is interchangeable. Service and overhauls of the OXE Diesel can thereby be performed away from the boat and the unit can simply be replaced in the meantime. This minimizes the downtime of the boat and increases the uptime for the operation.

As all OXE125 - OXE200 enable clockwise and counterclockwise propeller rotation, the user is free to place the engine on any side of the stern, thus reducing the need for several spare engines to ensure redundance. Due to the belt tensioner system in the OXE300, changing the rotation is somewhat more time consuming.  


The OXE Diesel is designed to be safe in any environment. Robust design, low-speed control and a quick-shift capability lead to safe operations under adverse conditions. Diesel is a more available and a less flammable fuel than gasoline, therefore, it is much safer to work with than gasoline within all working environments.

The Advantages of Diesel Fuel

Single fuel – since most commercially used marine engines run on diesel, there is the possibility for a single fuel fleet, if the outboard engines run on diesel as well. This eliminates the need and logistics around handling two types of fuel and makes it possible for every vessel in the fleet to refuel from each other. This is also in line with the NATO single fuel policy, stating that all units that can run on diesel should run on diesel, that came into effect in 2015.

Flexible fuel - the OXE Diesel engines runs on EN 590, ASTM D 975 No. 1 and No. 2, and JIS KK 2204, F54 and F75 ,which provides users with high flexibility and a readily available fuel. HVO100 and other BioDiesels fuels are sustainable options to utilize which significantly reduces the environmental impact.  When running on BioDiesels it is recommended to install a pre-filter in the diesel tank to avoid the risk of growth in fuel tank.

Less flammable than gasoline – Diesel is a less flammable fuel and therefore safer to work with in hazardous environments than for example gasoline. As the OXE Diesel is non-spark ignited, the engine models are also allowed into restricted environments that is out of reach for spark ignited products such as gasoline outboards.

Higher energy density – Diesel has a higher energy density than gasoline which provides the engine with a higher efficiency and torque, ensuring enhanced acceleration and lower fuel consumption. The inherit energy density of diesel also means increased range, compared to an equally powerful engine that runs on gasoline. The higher energy density of diesel facilitates extended operational periods and increases the time duration between refueling.
