Electric Marine Propulsion
Move towards quieter, lower-emission boating with an electric propulsion system planned around your vessel’s power, range and operating requirements.
Smooth Torque Marine assists with the assessment, planning and integration of electric propulsion systems for suitable recreational and commercial vessels.
Every electric vessel begins with the same question: what must the boat achieve on the water? The answer determines the motor, battery capacity, charging and control systems required.

Electric Power Designed Around the Vessel
Electric propulsion delivers power directly from an electric motor, supported by an onboard battery and charging system.
It can provide near-silent operation, instant torque and fewer moving components than a conventional combustion engine. The practical range and performance, however, depend on vessel resistance, speed, payload, battery capacity and charging access.
A successful electric propulsion system is not simply a motor replacement. The motor, battery, charger, controls, cooling, monitoring and drivetrain connection must be selected and integrated as a complete package.
Electric Propulsion Services
- 01
Vessel Suitability Assessment
We review the vessel, current propulsion arrangement, intended use and performance expectations to determine whether electric propulsion is a practical option.
- 02
Motor and Drivetrain Planning
The propulsion motor and its connection to the vessel must suit the required power and existing or proposed drivetrain arrangement.
- 03
Battery and Charging Requirements
Battery capacity and charging options are planned around the vessel’s expected operating time, range and access to shore or onboard charging.
- 03
System Integration and Commissioning
Controls, monitoring, protection and supporting electrical equipment are integrated and tested as part of the complete propulsion system.
Where Electric Propulsion
Can Make Sense
Where Electric Propulsion Can Make Sense
Electric propulsion is most practical when the vessel’s operating profile can be clearly defined and supported by an appropriate charging strategy.
- Tenders and harbour vessels
- Day boats with predictable range requirements
- Displacement vessels operating at efficient cruising speeds
- Workboats with regular access to charging
- New builds designed around electric propulsion from the beginning
Higher speeds require significantly more power, which directly affects battery size, weight and range. These trade-offs need to be assessed before a system is selected.
Electric Marine Propulsion FAQs
How far can an electric boat travel?
Range depends on the vessel, speed, battery capacity, weather, load and operating conditions. It must be calculated for the individual vessel.
Can a diesel inboard be replaced with an electric motor?
Some vessels may be suitable for conversion, but the drivetrain, available space, battery weight, charging and expected performance must first be assessed.
