EA advantages:
1. Low cost.
2. Ease and versatility of installation.
3. Direct drive - no belts and pulleys or gearbox.
4. Totally enclosed brushless PMAC motor designed for direct-to-prop use in marine applications - with integrated thrust bearing and excellent torque at a wide range of speeds.

6. Solid state relay (an EA exclusive) that increases efficiency and allows the system to be left on all day without draining the battery.
7. Designed by an experienced sailor for serious sailors - without pretense or nonsense.
8. Support from the designer and manufacturer, on the telephone or by mail or email.
