How to Use a 50 Amp Breaker With a 50 Amp Max Draw Trolling Motor

Trolling motors are small, lightweight motors that can be attached to either the bow or the transom of a boat. These quiet engines are used by fishermen as backup motors so they can quietly move from spot to spot in fishing waters. Unlike their gas powered counterparts - the outboard motor -- trolling motors are powered by a 12- or 24-volt battery system. A 50-amp max draw trolling motor is just that: It can only draw 50 amps of power. This is because the engine has a built-in 50-amp breaker (or fuse) which prevents overdraws of amperage, which can cause short circuits. The 50-amp breaker is installed inside the trolling motor.
