... You can select a hand tiller, foot switch, or laser wireless. The foot switch controller is the most popular. It connects through an electrical cord and leaves both hands free for fishing A trolling motor is rated by the amount of thrust it exerts. Thrust is what counts the most. While motor output in terms of horsepower will have an impact on trust, propeller shape, pitch and dimensions, and the motor speed in RPM work together to create the thrust rating. The propeller is especially important and is designed to achieve maximum acceleration and immediate response. Next up for consideration is the battery. You don’t want to skimp in this area. It’s very frustrating to have a trolling motor stop due to a dead battery. For example, a trolling motor that takes 40 amps is purchased. You will be using the motor for an average of six hours at about half load, so that would be 20 amps continuous drain over the six hour period. This motor will need a battery pack of 120 Ah just to keep operating over the full six hour period. To keep the above trolling motor operating without damaging the batteries, a battery pack rated at 240 Ah should be used. This keeps deep cycling at about 50%. Ideally, you should select a battery pack for this scenario that is rated at 20 amps for 10 hours. This would cover you in case the motor is used at greater than 50% power for an extended period ...
