Electric Motors are a
great way to power a model boat. Especially if you need a boat that is both quiet and super
portable. To extend the life of any electric motor, be sure to run a cooling coil on the motor to
remove unwanted heat
generated from running your boat.

Electric motors are also very "torque'y"
and can turn high RPM very reliably. These motors also range in shape and size.
Some boats use two motors driving a gear box to drive bigger props. Starting at a $20 Stock 05 motor, going to a Graupner Turbo 700 at about $40, all the way up to $200
for an Astro
Flight 05. Motors are available in different voltages and there are also 3 sized "cans" 550-size is stock
(05 size), 540-size is
"Pro". Then there is Graupner Speed 700 size of 1-11/16" diameter and
a 5mm output shaft. This motor is available in 9.6V or 12V for the modelers
looking for all out performance and top speed.

TIP: Changing the number of cells
(increasing) will give you a higher voltage and make your boat go faster.
Changing the Prop will also make your boat go faster but put more load on the
motor drawing more current (amps). Both increasing the number of cells and changing
the prop to one with a bigger pitch will increase the amount of heat generated
by the electrical system. This can be solved with water cooling the various
components.
Below is a basic Electric boat drive line (with a variable speed
control):

in an electric boat (note cooling coil around electric motor)
Electronic Speed Control (ESC)
and Micro Switchs (MS) are more reliable and generate less heat than the resistor
type of variable speed controls. Thus ESC's and MS's the most common way to
regulate the power from the batteries to the electric motor. Always run a fuse
in line!

Silicone wire with good
connectors like Deans can also carry more current than regular wire.
