Buying Guide

Match prop to motor horsepower

Choose a prop rated for your motor’s HP or thrust—options include trolling-motor props (measured in pounds of thrust) and small outboard-compatible props for 15–35 HP

Consider blade count and design

Two-blade props offer simplicity and efficiency for trolling motors, while three-blade or aluminum designs can improve load handling on small outboards

Look for weedless features

Weedless or wedge-style designs reduce vegetation buildup on trolling-motor props, improving performance in weedy waters

Check materials and corrosion resistance

Aluminum props are common under $100 and provide a balance of durability and cost—verify any coatings or OEM compatibility for saltwater use

Verify fitment hardware and mounting

Confirm included hardware or required prop-nut/pin sizes and manufacturer compatibility to ensure a correct fit with your motor shaft
