»» E-TECH website

E-TECH is a subsidiary of boatbuilder Starboats that was started in 2008 because they were dissatisfied with other electric motor offerings in the market at the time. The company has developed fixed pods, steerable pods and outboard motors that all utilize an in-water BLDC (BrushLess DC permanent magnet) pod motor in a watertight aluminum casing. The inboard motors are designed to fit any engine bed and any propeller shaft. For in-line hybrid applications, there are shaft endings on both ends of the engine to make an easy and quick in-line installation.
