Going Green with Elco Electric Motors


Running our Westerbeke 71C four engines 17 hours a day, 100 days a season for 12 years straight has forced us to look at repowering our launches.  As marine engine technology continues to evolve and non traditional alternatives become more prevalent we have had the idea of repowering our launches with electric motors.  During our analysis we’ve accumulated a variety of data and throughout our research we have been very impressed with the Elco AC induction motors.  As a result, we have become an authorized dealer and will be selling Elco motors in 2019.  We are excited to be bringing this line of GREEN marine motors to Nantucket.

The Elco EP Motor is ideally suited for displacement and semi-displacement hulls from 15′ through 85′, such as sailboats, launches, catamarans, trawlers or any vessel that travels at hull speed.  It’s AC induction motor is more efficient than its DC counterpart by a factor of 20% to 40%, depending on the load. It creates a lot more torque, accelerates faster, and since it has no mechanical connections, other than the ball bearings at each end of the rotor, maintenance is minimal. In short, it is a simple, rugged and reliable design.

Furthermore, an AC motor is more receptive to electrical regeneration – it naturally wants to regen.  Run it as a stand-alone motor and recharge at the dock, or hook it to a diesel generator, wind or solar power, or propeller regeneration to for virtually unlimited range.

The Elco EP Motor comes in 6 different sizes, ranging from a 5 horsepower equivalent to a 100 hp unit for boats between 50 and 80′.
