When selecting an engine to power your vessel, conventional wisdom often leads us to focus on engine horsepower (hp) as a primary indicator of boat speed. This approach holds true for gasoline engines and applications with minimal payloads, like motorcycles or cars. However, the dynamics change dramatically when it comes to waterborne vessels.

Vessels face substantial resistance from the water they displace, necessitating a unique perspective on engine performance. This is where the issue arises with gasoline engines, which typically exhibit low torque. Consequently, to access 30% power from a gasoline outbaord, you often find yourself revving up the engine to circa 60% of its capacity. In fact, it’s common to experience a noticeable increase in engine power only when you surpass the 70% mark on the throttle.

This predicament becomes even more pronounced when dealing with heavier vessels, where the engine may struggle to exceed 70% to 90% of its maximum rpm due to a lack of torque. Consequently, what you believed to be a 90hp outboard engine may effectively deliver only 65hp in real-world applications.

So, the pivotal question arises: Is horsepower (hp) or torque more crucial for your needs? The answer lies in your specific application, but for many professionals who must transport equipment and crew throughout long workdays, torque often takes precedence. It serves as the initial factor to consider, followed by a careful examination of propeller speed to ensure you attain the desired top-end velocity.

While most gasoline outboard manufacturers keep torque curve data closely guarded, providing limited access to this vital information, we take a different approach. At our innovative UK-based engine manufacturing company, we provide transparent access to torque and power curves for the Dtorque engine on our website, empowering you with the knowledge needed to make informed decisions for your marine endeavors.

Why Neander

With more than 1M engine hours in the field, in addition to our own testing, the Dtorque 50 is an engine that will always get you home safely.

Dtorque landscape

Your time is your money.
Minimise your downtime

Neander has partnered with world renowned supply partners to source premium parts for Dtorque outboard engines. The Neander Dtorque 50 offers service intervals of 250 hours versus the 100 hours on an equivalent gasoline outboard, meaning you can focus on day to day operations.


Life made easier,
cleaner and greener.

With full compliance with EU RDC Stage II regulations, the Dtorque 50 is a low emissions outboard engine. Besides using on average 40% less fuel than equivalent gasoline outboards, a huge advantage to running a Neander Dtorque 50 is the ability to access low emissions zones.

Refined engineering for unrefined environments

The Dtorque has been engineered from scratch, utilising innovative new technologies to deliver optimum performance even in the most challenging environments.

Neander Dtorque Engine

Spaceball Technology
Designed for Smoothness

Two of the key innovations of the Neander Dtorque 50 are the Dual Crankshaft and revolutionary Spaceball Design. By generating opposing forces, the Dual Crankshaft eliminates almost all vibrations and oscillations that would otherwise arise on the control axis, which would make it difficult to use such a small and powerful two-cylinder diesel engine. The advantages for the user are obvious: reduced noise, vibration and odour and greatly improved manouverability.
