able to cruise?
approximately what % of full throttle do
you expect to use on average?
is the weight and size of your boat?
are the physical dimensions of the battery
area that you have?
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

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) does 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.

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

also a dual motor top-mount throttle control
available for $1,362.00 USD.
Add $448.00 USD for smaller outboard motors
for the basic remote
throttle lever option that mounts vertically
beside the driver seat (can mount on either
side of the boat).
you need a high Voltage DC Disconnect Switch(s)?
to the ABYC Marine Electrical Code Book,
the answer is "YES". For all electric

one for the main positive and one for the
main negative power cables.

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.
Why is our electric marine
motor the most efficient?
The 3 Phase 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.
Regeneration - Your dragging propeller is an energy resource.
Tap this energy to 'top off' the batteries while under sail.
MOTOR YACHTS - YOU CHOOSE WHICH SYSTEM IS BEST Pure
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.
Electric Parallel - Due to the complexity and costs involved
Elco only offers this OEM boat manufacturers.
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.
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.

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. Below is a graphical representation comparing Diesel
fuel consumption for an Elco electric propulsion system using
lead-type batteries versus a diesel engine. NOTE: With Lithionics
Battery Lithium ion batteries, the savings and ranges will be
What size Elco Electric 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.
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

table also gives boaters an idea of what sort of investment they
will be looking at.
Many boat owners will find that for a variety of reasons, the
viable solution for their vessel is a hybrid diesel-electric propulsion
system. Whether you are looking for extended range or looking
for a compromise between an all-battery solution, we can assist
you to get the right system for you and your vessel. Below is
