Cooling
To obtain the highest possible efficiency, the electric motor and
motor controller are cooled by liquid.
There are two options:
- Raw water cooling system
- Keel cooling system
Depending on the E-LINE version, connect the cooling water hoses,
12 mm (15/33"), to the motor as follows:
6.1
Raw water cooling (fresh water only)
In this way of cooling, outside water flows through the system.
Heat is directly dissipated to the outside water.
• To filter raw water, always use water filter FTR140 in combination
with the fine-mesh filter element FTR140FM.
• Always mount the water filter and water outlet above the water
line. Attach the water filter to a vertical bulkhead.
• Always install an shut-off valve on the water inlet scoop!
• For both connections, water inlet scoop to water filter and water
filter to motor, always apply flexible hose.
• Check the water filter before each use and clean it if necessary.
6.2
Keel cooling
With this way of cooling, coolant circulates through the system. Heat
is dissipated to the outside water through the keel cooler.
Keel cooler
The keel cooler (1) must be placed, on the outside, against the bot-
tom of the hull.
When choosing the position of the keel cooler, take the following
into account:
- The keel cooler should be placed where a continuous flow of
water is guaranteed under all circumstances.
- Near the bow, where turbulence may occur at higher speeds, is a
less suitable location.
