The EP “Pure Electric” System uses only batteries so there is no gas, diesel, or oil aboard this vessel. The electric motor requires no maintenance and has an expected service life of 50,000 hours. The Pure Electric is perfect for sailboats and other displacement and semi-displacement hulls.


The Elco EP Motor is pure torque, unlike a diesel that uses belts, pulleys, and many other moving parts. The diesel motors moving parts create losses in torque and on average, only 40%-60% of the power created is actually used to propel your vessel. –Further, the motor only reaches full torque at one particular point in the torque curve.

An Elco EP Motor contains only one moving part and provides full torque throughout most of the torque curve. The EP motor provides full torque at 1RPM, all while operating in complete silence.
