DESIGN AND PERFORMANCE

The cowling of the OXE Diesel is developed to reflect the strength of an ox; a clean, strong design with large non-reflective surfaces joined together by clear edges. It is broken up into individual pieces that are all easy to replace without having to replace the whole cowling. The top of the cowling is flat, designed to be used as an extra service surface, or a step for the user when moored, or even a table if needed.  The only organic curve allowed is the shape of the ox-like bend that transcends from the waterline all the way to the top of the engine. The bent neck has a purpose; to be easily removed from the back to allow for easily accessible service points.

The powerhead in the OXE Diesel is a proven, robust diesel engine developed by the automotive industry. Inspired by modern inboard technology, the powerhead of the OXE Diesel is mounted horizontally and marinized with a closed-circuit coolant system.In relation to a vertically mounted outboard engine, a horizontally mounted engine reduces wear and improves heat dissipation. The marinization of the engine include separate systems for seawater, heat exchangers, intercooler and oil cooler. All system functionality ensures that the engine, electrical system, fuel system, and air intake withstand marine conditions.

The use of state-of-the-art diesel engines further escalated the requirements on the power train. The bevel gear systems found in traditional inboard and sterndrive power trains, with vertical shafts and dog-clutches, are neither designed for nor able to cope with, the high torque required or long hours demanded by commercial marine applications. The primary transmission provides the user of OXE125-200 with the ability to change the gear ratio of the unit to fit various demands and driving styles. Depending on the needs of the operator, high torque or high-speed can be selected for OXE125-200. It's designed as a separate unit that is easily reversible. By switching the orientation of the primary transmission housing, the user can change the gear ratio between 1.73:1 and 2.17:1. The OXE300 comes with a fixed gear ratio of 1:39:1.

The gearbox is mounted separately, under the powerhead but above the waterline. It is therefore protected from damage if the unit runs aground. The gearbox is a robust electro-hydraulically operated system with two multi-plate clutch packages that allow for high torque and power transfer.
It is designed to withstand crash stops and operates both clockwise and counterclockwise to allow the user to mount or even transfer the OXE Diesel on any boat and between different configurations. Propeller rotation is simply selected from the display settings.

The patented primary belt transmission allows full range torque transfer capability without affecting the hydrodynamics of the OXE Diesel. It means that solutions that were previously only available for inboard applications can now be applied to outboard solutions. The introduction of the primary belt transmission also means that the bevel gears found in most leisure products can be completely removed for a more durable and efficient solution. The belt drive allows for increased torque transfer to the propeller, as well as for smaller torpedoes and slimmer submerged modules under the waterline. The result is a design with less drag, which reduces fuel consumption and increases speed in comparison with bevel gear-driven units.
