Boat engines

Minn Kota is the world's largest and oldest manufacturer of electric outboard motors. Among other things, Minn Kota developed the turbo electric motor technology the Cool Power technology.

Cool Power Technology:
Many motors reach motor operating temperatures of up to about 260 °C after only a few minutes. Hot engines can not work efficiently   and lose up to 1/3 of their possible power during a longer driving time. Engines with the Cool-Power technology operate with temperatures that are  100 °C lower operating temperatures.
