Electroprop provides you with complete systems packages for converting your sailboat into an electric boat.  Each system includes the drive motor, gearbox, motor mounts, mounting system, cooling system, batteries, battery chargers, AC distribution, DC distribution, shorepower and propeller.   Systems 48 volts and higher feature double pole breakers, battery monitoring and ground fault monitoring.   All systems can be customized per your requirements.

Electroprop is the only company selling complete systems packages engineered for the higher currents and voltages associated with Electric Propulsion.



Helical Drive systems fit better into many smaller boats.  Electroprop Helical Drive systems are first in class for efficiency.   Helical Systems have a lower drive coupling and come in many different lower gear ratios which typically are better for smaller boats.   Lower ratios are typically better suited for smaller propellers.    Electroprop Helical drive systems are capable of running up to 3,000 rpm.  Electroprop Helical Drive Systems run at up to 2,100 rpm.

The Mariner  is a modular, open frame, low profile system for powering boats up to 10,000 lbs and 32 feet in length.  The mariner enables you to jump from diesel to the safety of electric on a minimal budget.   These are small and powerful machines that we have built for over 10 years.   The Mariner has a permanent magnet AC motor with helical gearbox.

The Sailor   is built on the foundation of The Mariner.  The unit is self contained and complete,  all you have to do is connect the Sailor to the DC source and start operating straight away.  The Sailor has a fan pulling air out from near the motor, and ducting for bringing cool air into the drive unit.  The Sailor has a permanent magnet AC motor with helical gearbox.   The Sailor is recommended for vessels up to 34 feet and 12,000 lbs.

The Islander   has two fans, one blowing cool air into the enclosure, and one expelling warm air out of the enclosure.  The controller, contactor and wiring harness are installed in a plug and play package.  The Islander has a permanent magnet AC motor coupled to a helical gearbox.   The Islander is recommended for sailing vessels up to 38 feet and 14,000 lbs.



Planetary Drive systems are smaller, lighter and more powerful and tend to fit better into larger vessels.    Planetary drive systems have 3 different gear ratios:  3, 4 and 5:1.   Planetary drive systems are capable of running up to 6,000 rpm.   Electroprop Planetary Drive systems run at up to 4,500 rpm.   All Planetary Drive systems have wiring harness components mounted inside the DC distribution box.

The Racer is a very lightweight system for racers, and very compact system for boats with minimal space.   For instance we are currently building a Racer to replace a Vdrive system.   The installer is responsible for mounting a fan or fans for providing cool air flow across the motor.  A transverse beam is required for installation of the Racer in an electric boat.   The Racer is recommended for vessels up to 12,000 lbs.  The Racer Plus is recommended for vessels up to 17,000 lbs.

The Seafarer is an air cooled planetary drive system for sailboats up to 17,000 lbs.  The Seafarer casing includes two fans that both push and pull air through the drive enclosure.

The Cruiser is air and water cooled.   The Cruiser is both air and water cooled for high sustained loads found in a Cruising Sailboat.  The Cruiser utilizes permanent magnet AC motor technology with planetary gears.  The Cruiser is recommended for vessels up to 40 feet, 20,000 lbs.

The Voyager is both air and water cooled with planetary gears.  The Voyager is recommended for vessels up to 60 feet and 44,000 lbs.  Two of these drives could be utilized on a vessel larger than 42,000 lbs.
