Trolling motors are popular with anglers who want to be able to maneuver around a fishing area without disturbing the fish below the surface. When youâre searching for a new electric boat motor, keep these points in mind: 1  Most trolling motors operate on 12 volt, 24 volt and 36 volt circuits.
Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. when fishing from a jetty. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish.
