Elco EP System – Electric Boat Propulsion at Its Finest

The Elco Electric Propulsion System is well engineered using advanced technologies for reliable and outstanding performance. All of Elco’s products are built in the USA.

Elco Electric Motor: Cool, Quiet & Powerful

The entire propulsion system, excluding instrument panel and batteries, is contained in a water resistant cast aluminum finned housing that contains all of the electronics, AC motor, and safety devices. The system is mounted directly in place of a typical marine diesel or gas engine. Whether on the sound, around the bay, along the lake, or on the river, it is highly valuable to protect our waters. The Elco Electric Propulsion System is a highly efficient and extremely durable alternative to fossil fuel options.

* Performance may vary based on operating conditions. The figures provided above relate to travel at between 60 – 80% of hull speed.

** Shore power-50% depth of discharge

To convert from nautical miles (nm) to statute miles multiply nm by 1.15.

With Electric Hybrid system additional kilowatts should be added depending on house loads (1,000 watts equals 1kW)
