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.

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 and charger. This includes the 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.

The Elco EP Motor is an asynchronous (or totally enclosed) and bonded three-phase brushless AC induction motor, that provides extreme reliability and efficiency with only one moving part, (the rotor), mounted on two permanently sealed deep grooved ball bearings.

The bearings have an operational service life of 50,000 hours.

This “plug & play” system has all the wiring and active power components completely enclosed in a marine grade aluminum casting which is rated at IP-65.

Elco has a great selection of quality battery chargers that meet the needs of every Elco System. Upgrades are available for a quick charge system.

Monochrome LCD Display Screen

Elco is the only company that offers this precise and informative “real time” information.

The battery bank settings are programmable.

Fault signals: The fault information accurately tells the skipper exactly what the condition of the system is. This eliminates time consuming guesswork and trouble shooting for faster repairs.

The plug is water tight and connects to its mate on the wiring harness.

Single pole, two position “OFF/ON”

IP-65 Rated

Water tight plug that connects to its mate on the wiring harness.

Built-In Safety Feature: If the system is turned on and the throttle is already in gear, the system will not operate, a red light will flash, and the energy gauge panel will identify what the fault is.

15′ Standard Length

Elco offers a sealed assembly system that provides “precise variable speed control”. Throttle can be thrown into reverse immediately for shorter stopping distances and better docking ability.

Sealed assembly system that provides smooth shifting from forward to reverse and back.

Chrome plated for protection from corrosion and is also available in black and white.

The plug is water tight and connects to its mate on the wiring harness.

Side mount throttle is also available.

High power LED Light confirms that the system is engaged and ready to go.

The Power on light is water tight and connects to its mate on the wiring harness.

When facing headwind or some chop, push the Power Boost Button and you will increase your RPM’s and amperage to maximize power for a short period of time. After releasing the Power Boost Button, the motor will automatically return to the preprogrammed or optimum cruising RPM. Elco is the only electric propulsion system that offers this incredible safety feature.

The Power Boost Button is a water tight plug that corresponds to its mate on the wiring harness.

Elco’s AC controllers come in compact, fully sealed housings with advanced thermal management. These controllers combine power and smoothness with a Programmable Logic Controller to provide rugged strength and unequaled flexibility.

15′ Standard Length

Five different water tight plugs that connect to each instrument’s water tight plug.

E-Power Electric Hybrid options include generators and/or solar/wind components to meet continuous cruising needs.

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.

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

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.

All Electric

With the all electric configuration, an electric motor powered by batteries drives the propeller shaft. This system is ideal for day cruises in displacement and semi-displacement boats such as sailboats, launches, tenders, and sloops. Installation is simple, and the motor fits most standard motor mounts. The batteries can be strategically positioned to keep the boat balanced.

Hybrid Electric Serial

Similar to the all electric configuration, the electric motor drives the propeller shaft directly. The difference is the addition of a gas or diesel generator, which has no direct connection to the propeller shaft. Instead, the generator powers the motor and charges the batteries. This provides boaters with the option of running the motor strictly off battery power for a quiet, clean boating experience, or switching to the generator when the batteries are low. The serial hybrid-electric configuration is great for boaters who go on day cruises and want to have a backup power supply should a trip take longer than battery power alone can sustain.

Hybrid Electric Parallel

The parallel hybrid-electric configuration features a diesel or gas motor that is connected to the propeller shaft through an electric motor and a clutching system. The parallel hybrid-electric configuration allows the motor to drive the propeller directly and charge the batteries while the electric motor is inactive. With the flip of a switch, the vessel can switch to exclusively power the electric motor with batteries for situations when the motor would be inefficient.

Hybrid Electric Parallel Serial

Elco’s EP hybrid-electric parallel and serial system benefits commercial and pleasure vessels. Tugboats employed by harbor services can use a combustion motor to get where they are needed in a hurry. However, most of their time is spent idling or actively maneuvering to support other vessels. In these low-speed situations, the combustion motor can be shut down so the system can switch to the electric motor for more efficient operation.
