Minn Kota 4" Motor Rebuild Kit for Newer Style Trolling Motors
Bring your trusted Minn Kota trolling motor back to peak performance with this comprehensive 4-inch Motor Rebuild Kit. Designed specifically for newer Minn Kota freshwater and saltwater motors with a 4" diameter lower unit (housings), this kit contains all the essential, genuine replacement parts needed to complete a full service and reseal of the motor head.
Over time, the seals and brushes in your trolling motor can wear down, leading to water intrusion, decreased power, and eventual motor failure. Water in the lower unit is the number one cause of trolling motor issues. This rebuild kit addresses the problem at its source, allowing you to restore the integrity of the motor's seals and replace critical wear components, thereby extending its life and ensuring it operates with factory-level power and efficiency.
Whether you are performing preventative maintenance or repairing a leaking lower unit, this kit provides everything you need for a professional-grade reseal. All components are genuine Minn Kota parts, guaranteeing perfect fitment and the highest quality standards.
