How to Use This Calculator
- Enter your boat's overall length in feet (e.g., 16 ft for a typical bass boat).
- Input the loaded boat weight in lbs — include passengers, gear, fuel, and the motor itself.
- Select the worst conditions you regularly fish in: calm lake, moderate wind, river current, or rough water.
- Read the Recommended Thrust in lbs — choose a trolling motor at or above this value.
- Check Battery Capacity Needed to size your deep-cycle battery for a full 8-hour day.
- Use Runtime on 100Ah Battery to estimate how long a standard battery will last at average throttle.
