You are on our: Torqeedo 503/1003 electric outboards page

The new 503 and 1003 motors from Torqeedo are additional models to the popular and highly-rated 401/801 range.

The main differences are:
- Higher Power (500 and 1000W respectively)
- Waterproof Casing, so even if you drop them in the water they will still work. Try that with a petrol, or any other electric motor!
- Built-in GPS & Digital Display, showing battery charge state, speed, range and power draw.
- Kick-up Drive Leg if you hit an obstruction or go into shallow water.
- 30% Higher Battery Capacity than 401/801 (1003 model)
- Solar Charging Option

As battery life is usually the main worry for those new to electric power,
the digital display is very reassuring, if nothing else. Range is inversely
related to speed, so if you have further to go than currently indicated,
simply slow down until the range increases to the required distance. As a
further precaution an alarm sounds as you pass below 30% capacity, with
the display flashing a recommendation to slow down.

The battery capacity supplied with the 1003 is 400 Watt hours (ie 13 amp
hours at 29.6 volts); and the 503 300 Watt hours (ie 10 amp hours at
29.6 volts). Because they are lithium manganese based, the full capacity
can be used without detriment to the battery lifetime (unlike lead acid
batteries, which dislike being discharged more than 40-50%).

TORQEEDO SOLAR PANEL
Torqeedo's new CIGS (Copper Indium Gallium Diselenide) solar panel offers up to twice the efficiency compared to conventional thin film solar cells. Combined with the low energy consumption of the highly efficient Torqeedo outboards, running your boat from solar power alone is possible.

From a surface area of about 1 m², the flexible, folding solar panel will charge the batteries of the Travel 503/1003 quicker than the mains! If you connect it while running the motor, you can achieve between 1.0 and 2.2 knots from the panel alone (depending on boat). 



Measurements
Unfolded: 133x76x0.3cm
Folded: 39x22x3.5cm
Weight: 1.6 kg

Charging
A mains charger is included in the price of the Torqeedo 503/1003, and
will take 8-10 hours to recharge a fully discharged battery. It is also
possible to charge direct from a 12volt source such as your car or boat
battery (but the wiring for this is not supplied).

Handling/Storage
The shafts on the 503 and 1003 don't fold (like the 401 and 801 Travel
models), but the battery is still very easy to remove, making handling
on/off your boat much easier. For example the 1003 weighs approx
30-lb in total, of which 10-lb is the battery, so you only ever need to
manhandle 20-lb (less than any petrol motor on the market today) at 
once. Also, unlike modern (four stroke) petrol motors, you don't have
to worry about laying them down on one particular side, or even about
getting them wet, which makes storage straightforward too.

Not to mention the relative silence, ease of use and lack of pollution!
