Battery System: Please note that the Elco motors as priced do not include a battery system. Customers can source their own deep cycle battery system or we can offer a variety of battery systems: Lead-acid batteries: lowest cost, heavy, bulky, require maintenance, lowest life expectancy/ cycle life (up to about 600 cycles) AGM batteries: moderate cost, heavy, bulky, require less maintenance, improved life expectancy/ cycle life (up to 1,000 to 1,200 cycles) Lithionics lithium-ion batteries: best overall system with highest performance, next to zero maintenance, lightweight, compact and exceptional life expecatncy - up to 5,800 cycles at 50% discharge rate. The only downside is these batteries cost significantly more than lead-acid batteries. In order for us to specify and quote a battery system we ask that you provide us the following information: For how many hours per day do you want to be able to cruise? At approximately what % of full throttle do you expect to use on average? What is the weight and size of your boat? What are the physical dimensions of the battery area that you have? Please tell us about the electrical outlet(s) you have access to to plug the battery charger into. Example: 110 Volt AC outlet on a 15 Amp circuit breaker 100 feet away from the boat. Please let us know if you have any roof or deck space available for possible rigid or semi-flexible solar panels and the dimensions of such areas. With this information we can then calculate the Amp hours of battery capacity required to give you the desired running time before recharging. Depending on your budget and other factors we can then quote you some battery options. Please keep in mind that to be able to run all day at a high percentage of throttle may require a substantial battery bank. For many small boats (under 25 feet) we can provide an economical battery system that can provide a few hours enjoyment but many small boats (such as a 10 foot tender boat) may not have enough available space or carrying capacity for a battery bank that can run the motor more than 1 or 2 hours at high throttle. For applications that require longer running times the most economical way to go may be what we call a "hybrid-electric battery system" where we can decrease the size and cost of the battery system by adding a Polar Power DC diesel generator or other type of generator. Elco Electric Inboard Motor Service Notes: In the unlikely event that something goes wrong with the Elco electric inboard or outboard marine motor there are lights that flash on the electric controller (located under the engine cover on the top of the motor) and that tells us what is wrong. It really depends on what the controller tells us as to whether the motor can be repaired quickly and easily locally or if it needs to go back to Elco for repair. Elco Inboard Motors: Please read the instruction manual on the inboards (click on PDF link below). We will help with a correct prop solution: we need the boat specs and what the diameter of the prop that the owner wants to use. It is very important that the pitch is correct other wise the motor will not function correctly - you can either go in over Voltage or under Voltage and you will not get the performance that you should from the motor and this can cause problems. There is a procedure that is in the manual for the inboards – you need to water test and take down the speed you are going and the rpms and the Amps the motor is pulling (all that is displayed on the display that come with the unit but you will have to use a hand held GPS to get the speed data) at first low speed, then half throttle and then full throttle. This will tells us if the pitch is correct and you are getting full Horsepower and reaching 1,500 RPM. Click here for the Elco Electric Inboard Marine Motor Instruction Manual

The components of each Electric Inboard Marine Propulsion System includes: Elco high efficiency electric motor Battery Charger E-Gauge VII - color display Throttle Ignition Key Power On Light Power Boost Button Controller/AC Inverter 15 foot Pre-Wired Harness All Elco system components are pre-wired for plug and 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.

What size Elco Electric Inboard Marine Motor is right for my boat?

There is some overlap between motor and boat sizes so choosing the right size motor for you and your vessel can sometimes require some personal expertise to make the right choice. In selecting the correct size electric motor, some general tips are - in areas with strong tides and currents, choose the next larger size motor, and the same goes for weight - if your boat is heavy for its length, choose the next size up.

Elco Motor Yacht has also developed a robust and easy motor coupling system to allow for twin or triple motor installations. This can be used when a vessel exceeds 85 feet or if you need a faster cruising speed. Please contact us about the motor coupling option by email.

The table below serves a good starting point for most boaters. The table also gives boaters an idea of what sort of investment they will be looking at.

NOTES: *Prices subject to change. Prices do not include freight/ freight related charges or currency charges. *2.25% Cash Discount offered for Cash, Cheque or Debit Card purchases. Prices are for a complete Elco Electric Propulsion System including motor, throttle (speed controller), charger, switches, E-Gauge IV and prewired 15 foot wiring harness. Additional options such as motor couplers and lithium-ion batteries cost extra. E-Gauge VII upgrade now included. E-Gauge IV discontinued (shown below center).

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.

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

ELCO MOTOR YACHTS - YOU CHOOSE WHICH SYSTEM IS BEST
Pure Electric
With the pure 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 engine mounts. The batteries can be strategically positioned to keep the boat balanced.

Hybrid Electric Serial
Similar to the pure 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 engine that is connected to the propeller shaft through an electric motor and a clutching system. The parallel hybrid-electric configuration allows the engine 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 engine 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 engine 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 engine can be shut down so the system can switch to the electric motor for more efficient operation.
