What size motor do I need?

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. Use the chart below for the approximate operating range for each motor. More detailed sizing information is available by visiting our Sizing and Pricing page.

How long can I go without recharging?

There are various factors in determining how far you can go before you need to recharge. Winds, tides, currents, weights, propeller type, vessel speed and battery size are some examples. With a generator on board running time can be extended or made continuous.

What do I get with my EP Motor purchase?

When purchasing an Elco E-Power System, you’re not just receiving a motor, you’re purchasing all the essential components to power the vessel with electric propulsion, excluding the batteries. This includes the Battery Charger, E-Gauge IV, Throttle, Ignition Key, Power On Light, Power Boost Button, Controller/AC Inverter, and 15’ Pre-Wired Harness. All Elco system components are pre-wired for “plug & play” installation. With batteries configured, your system can be up and running in minutes. Re-powering with electric is far less complex than replacing a diesel because there are no fuel, cooling or exhaust lines, throttle linkages, shifting linkages, or individual wires to deal with. E-Power Electric Hybrid options include generators and/or solar/ wind components to meet continuous cruising needs.

Elco recommends that your batteries and charger be planned and properly configured by a qualified marine electrician.

How do I charge?

Shore power – Charge for pennies a day by plugging into shore power at the dock.

Solar power – Solar panels continue to increase your system’s efficiency. Harness this resource to charge smaller battery banks over longer periods while staying off the grid.

Wind power – Wind is abundant and can be used to charge your batteries over longer periods.

Propeller Regeneration – Your dragging propeller is an energy resource. Tap this energy to “top off” the batteries while under sail.

Diesel Generator – Electric cruising can be extended or even become continuous when you have a properly sized generator on-board. Size a generator to an Elco EP Motor with the help of the Elco technical staff.

Why is our electric motor the most efficient?

The 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.

more torque, faster acceleration, super efficient
