DTORQUE TURBO DIESEL OUTBOARD ENGINE – 50 HP
The Neander Dtorque turbo diesel outboard engine sets a new benchmark in diesel engineering. The 804 ccm twin-cylinder aluminum powerhead delivers 50 hp at the propeller shaft.
With a remarkable torque output, peaking at 111 Nm at 2,500 rpm, the Dtorque’s performance surpasses even the leading 70 hp fuel injected, four-stroke gasoline outboards.
It offers exceptional capability when powering heavy loads at low rpm, as well as enabling the boat to get on plane quickly. This can be achieved, with excellent fuel efficiency, averaging less than 12 litres per hour at wide open throttle.
Is the Dtorque right for you?
At YANMAR, we understand that you should consider many different criteria when investing in an outboard motor. However, when you’ve got a serious job to do, you need the reliability of a diesel engine.
The Dtorque is the ideal choice if you operate or manage:
- work boats
- safety/rescue boats
- fishing boats
- governmental and port authority vessels
- passenger boats
- superyacht tenders
Diesel is less flammable than gasoline, and so the Dtorque is the safer choice for potentially hazardous environments, such as in the oil and gas industry.
Superyacht and cruise ship operators, for example, will also benefit from the time and cost savings associated with having fewer fire safety precautions and regulations.
In addition, there is only one type of fuel to manage, which is more widely available in ports all over the world. The Dtorque also exceeds EU RDC Stage II emissions regulations, however, is not yet EPA compliant.
Low Noise and Vibration
The Dtorque has a two-cylinder, common rail, turbo-charged diesel engine that uses a unique system of dual counter-rotating crankshafts in an aluminum block. This technology, with its patented ‘Spaceball’ design, helps reduce vibrations and noise.
Another advantage of these crankshafts is the lack of rotating and operating (steering) torques. This results in less fatigue during the engine’s operation.
HIGH Performance at Low RPM
For a burst of speed, the Dtorque delivers a creditable 50 hp, but its torque is the most important factor in a working environment. The Dtorque’s mighty 111 Nm at 2,000-3,000 rpm will get your boat quickly on plane and provide all the muscle you need when fully loaded.
Excellent cost of ownership
As the world’s smallest diesel outboard engine with common rail fuel injection, the Dtorque provides impressive performance while maintaining a best-in-class fuel economy.
At full throttle, it typically uses under 12 litres of fuel per hour. This equates to around half the average consumption of most 70 hp four-stroke gasoline outboards delivering a similar performance. As a result, the Dtorque requires less refueling stops, maximizing the number of working hours, and reducing the overall operation costs.
The expected lifespan of the Dtorque is more than 10,000 hours. This is, on average, more than double that of any comparable gasoline outboard engine and allows for extended service intervals.
