Conversion of energy into propulsive power and how Torqeedo electric boat engines compare

Navigating the complexities of power measurement is simplified with Torqeedo's introduction of the 'HP equivalent.' This transparent overview empowers our customers, showcasing that our motors deliver comparable propulsive power to combustion engines, all while requiring significantly less input power. It's a testament to our commitment to providing powerful and efficient boating experiences.

In the 18th century, James Watt introduced the term horsepower (HP) to measure the performance of steam engines, a metric that persists today alongside watts. Despite its commonplace use, there are often overlooked discrepancies in performance data due to varied measurement conditions. Understanding these nuances is crucial for accurate comparisons of drive efficiency. Key power measurements include:

Input Power
Input power denotes the power consumption of a driving mechanism and is often measured in watts or horsepower.

Shaft Power
Shaft power refers to the power of petrol outboard and is similar to how we measure a cars power – in horsepower or kW. However it doesn’t account for propeller losses, which can be as high as 30-80%.
Significant fuel savings
Propulsive power is the most comprehensive measure of a propulsion system’s performance, as it clearly quantifies the energy available for propelling the boat. And crucially, all potential losses are factored in.


Torqeedo adopts the long-standing practice of measuring large vessel performance in propulsive power, highlighting its significance. In contrast, petrol powered and conventional electric drives often omit this specification, resulting in substantial differences.

How to convert horsepower to electric propulsive power

At Torqeedo, sustainability and efficiency are at the core of our success. Our electric boat motors leverage state-of-the-art technologies, boasting the highest overall efficiency in the market. Through the meticulous optimisation of the drive train and the application of cutting-edge engineering, Torqeedo converts energy into propulsive power more effectively than conventional electric boat motors or combustion engines.

Electric Motors: The Driving Force

Ever wondered how electric motors work? Torqeedo's electric boat motors consist of three fundamental parts: the stator, the rotor, and the commutator.

This innovative design allows our motors to produce up to 20 times more torque than conventional electric motors, redefining high-performance boating with efficiency and reliability. The stator, a permanent magnet or electromagnet, is firmly installed in the housing. The rotor, made of iron with varnished copper wire wrapped around it, can rotate around the motor axle. The commutator, consisting of two current collectors in the form of opposing semicircles, sets the copper wire under current. This system allows for consistent torque across varied speeds, ensuring an unparalleled boating experience.
