Electric Boat Drive Systems are available for almost any type of
boat, and are capable of driving that boat at hull speeds comparable
with speeds produced by internal combustion engines. The big
advantage of electric drives are simplicity, ease of operation, and
quietness of operation. Cruising range using electric drives are
solely a function of the stored battery power and the rate (speed) of
discharge. Electric boats are generally designed and built so as
to move through the water easily. When an electric drive is to be
used to move a large sailboat, for example, a compromise must be made
with regard to speed and duration. Moving such a boat to clear
the harbor or to return to the dock from the mouth of the harbor is an
ideal application of electric power. The retrofit of an electric
drive systems is very practical; it is simple to replace a noisy,
smelly, and difficult to start auxiliary engine. The number of
batteries required generally fit into the existing engine space and the
total weight of the electric motor, controls and batteries are
generally less than the weight of the engine and fuel of the internal
combustion system.

Electric Drive Systems are very
simple. They consists of an electric storage battery, a speed
(voltage) controller with throttle, and a dc electric motor. In
order to have the boat's propeller turn at an efficient slow rotation,
a reduction gear is an integral part of the motor. To be able to
reverse the direction of the propeller there is a switch in the
throttle that controls a forward/reverse relay that alters the rotation
of the motor. To ascertain information about the operation of the
motor volt and ampere meters are provided; also a battery "fuel gage"
with LED readout informs about the power available in the battery
bank. A keyed lock prevents unwanted use of the system. The
batteries are recharged by plugging the line cord into the dock
receptacle. The recharging is automatic and rapid so that
overnight is more than adequate recharging time. The recharging
system automatically regulates the charging rate so that the batteries
will not be over or under charged. Completely sealed batteries
are used so that gas problems are minimized and spillage is not a concern.

Installation: Upper Right: shows the compact Electric Propulsion
Unit (a compact motor and reduction gear) that is about 18" long and
less than one foot high. This unit is placed in direct line with
the propeller shaft and is attached between the engine beds
stringers. System controls may be installed in a console as shown
(Above Right), or integrated into the various
features of the boat as (Below), where the meters are installed in
the seat risers (to the left) while the throttle is placed at the right
hand of the helmsman in the cover boards just above the name plaque, to
the right of the wheel

Compact Electric Propulsion Unit
has many advantages over Belts and Pulleys:
1. There
are fewer moving parts in the Electric Propulsion Unit.
2. The Electric Propulsion Unit has the required thrust bearing and is
sealed and lubricated.
3. Unified construction eliminates line-up problems.
4. No wet and soggy belts to break
5. No danger of fingers getting into belts and pulleys.
6. No need to tighten belts, adjust tension, or realign shafts.
7. The compact Electric Propulsion Unit uses less valuable space
than pulleys and belts.
8. Over one hundred speed reduction ratios are available, so that
it is possible to exactly match your boat's needs.
