Bass boats typically use outboard or trolling motors with enough horsepower to accommodate the size and weight of the boat. Most casual anglers use outboard motors with up to 150 horsepower, while professionals generally rely on more powerful 150- to 300-horsepower motors for their longer, larger bass boats.
One of the most important factors to consider while selecting a motor is the amount of thrust needed for maximum acceleration and maneuverability. Consumers can calculate the amount of minimum thrust needed based on the boat's maximum weight or its length. Bass Resource offers a chart to help determine minimum thrust. According to this information, a boat that's 12 to 14 feet long needs a motor with a minimum thrust of 35.
