Propulsion & Hydro-Generation

Oceanvolt power and propulsion systems consist of several key components;

a powerful regenerating motor, an ergonomically designed control lever, a propulsion battery bank, a charger and a motor controller.

Sunwater Marine offers complete Oceanvolt electric power and propulsion systems for either shaft or sail drive configurations.

The facts about electric power, batteries and propulsion. 

Today's electric motor technology has already moved from the open road to the open ocean.



Electric motors are in constant ‘stand by’ mode; you can engage the control lever at any time for instant forward or reverse propulsion.

Electric motors achieve instant torque with Electromotive Force while internal combustion engines need to build RPMs gradually by increasing piston firing frequency.



At sailing speeds over 6 knots Oceanvolt systems are able to generate significant power for recharging the battery bank by activating at the touch of a button.

Power regeneration increases exponentially with each additional knot of speed.


Lithium ion batteries are superior to other battery storage technology; highest storage capacity, high effective current delivery, high charge capacity resiliency and wide temperature range performance.

Our highly skilled technical team ensures proper installation and system-optimization.  The highest quality Li-ion batteries and battery management systems are used - to ensure performance and safety.


For those interested in a hybrid solution, generators are a highly efficient way to extend range while at sea.


DC generators have the advantage of rapid recharging capability.

AC generators are, generally, smaller and even portable which means that the generator can be aboard only in situations where longer motoring might be required.


Battery recharging is accomplished with shore connection, hydro generation (an integrated part of all Oceanvolt systems) and/or solar panels.

In Hybrid solutions, a generator (either AC or DC) can be used to recharge batteries / extend motoring range.



It is essential that all system components are properly selected and installed.

Our team of highly skilled technicians ensure that all components are compatible and that system management software is optimized.

"Maximum convenience, soundless, totally clean, no fuel spills."


" Since we first dreamt of sailing the world, we dreaded the smell, noise, vibration, and maintenance, synonymous with having a diesel motor on-board. So, we decided to build our own electric motor from used parts we found online. After 5 years and 20,000 miles...
