Product details

The Travel 503L delivers over 500 watts of input power and in terms of propulsion is comparable with 1.5 HP petrol outboard.
Its name says it all. With the Travel 503L you can discover the world on water, completely waterproof to IP67. Thanks to the on-board computer with its GPS-based calculation of the remaining range, you always have your own travel guide with you.
The Travel 503L is suitable for inflatables and other small boats.
  • Can do everything that a 1.5 HP petrol outboard can, plus it’s environmentally friendlier, quieter, lighter and more convenient
  • On-board computer with GPS-based calculation of remaining range
  • Solar rechargeable – including during the voyage
  • Can be easily dismantled for transport and space-saving storage
  • A clean affair: no matter how or where you store your Travel, there’s no risk of leakage or petrol smells
  • Stepless forward/reverse drive
  • Manual tilting device with grounding protection 4-step manual trim device
  • Completely waterproof (IP 67) Tiller control Integrated battery with 320 Wh Li-Ion
  • Total weight 12.9 kg (short shaft)) / 13.5 kg (long shaft)
  • Shaft length: 62.5 cm (short shaft) / 75 cm (long shaft)
  • Equipment included: Travel 503L with battery and charger
  • Warranty: 2 years for non-commercial use

Range and speed:

Speed Range Running time
Slow 2.0 kn (3.7 km/h) 12.8 nm (23.8 km) 6:20 hrs
Half throttle 3.0 kn (5.5 km/h) 6.4 nm (11.9 km) 2:08 hrs
Full throttle 4.0 kn (7.4 km/h) 2.8 nm (5.2 km) 0:42 hrs

Information on range and speed:

When travelling through water, displacement increases power required in proportion to the cube (third power) of the speed. This means that doubling water speed increases the power required eightfold.

Conversely, it of course also means that only a slight reduction in speed will increase the range attainable significantly. Simply reducing speed by e.g. half a knot has a considerable effect on the remaining range.

Since mental arithmetic to the power of three is quite tricky, the on-board computer of the Travel constantly calculates the remaining range for you. To do this, it combines the consumption data from the motor with the charge level of the batteries together with the speed over water obtained via GPS. This means you can read the remaining range in real time from the Travel's display. Using the TorqTrac App you can even read the remaining range from a map on your smartphone.

Charging batteries from the on-board power system
In some instruction manuals, it is written that an inverter is required to charge from an on-board power system. This is wrong.
What's correct is that: The battery can be charged with a voltage range of 9.5V....50V. The minimum current must be 4A.
Ideally, one should use the TORQEEDO DC charger, which is equipped with a cigarette lighter adapter and a 5.5/2.5 mm coaxial power connector.

If the battery is to be charged through this cable, it is essential to ensure that the connection's polarity is correct.
Check the position of the coaxial power connector: The center contact is POS, the external contact is NEG. Non-compliance can lead to damage occuring, which is not covered under the warranty.
