Revitalize Your Trolling Motor: The Complete Minn Kota 3-5/8" Motor Rebuild Kit

Bring your trusted Minn Kota trolling motor back to peak factory performance with this comprehensive motor rebuild kit. Designed specifically for models with a 3-5/8-inch diameter lower unit, this all-in-one kit provides all the essential components needed to perform a complete overhaul of the motor's core wear parts, addressing issues like water intrusion, noise, and power loss.

Over time and through hard use, the internal seals and brushes of any trolling motor will degrade. This can lead to water seeping into the sealed motor housing, causing corrosion, bearing failure, and ultimately, catastrophic motor damage. This rebuild kit is the definitive solution for preventative maintenance or for resurrecting a motor that has started to show its age. By replacing these critical parts, you can restore lost power, ensure quiet operation, and significantly extend the life of your investment.

This kit contains all the genuine-quality components required for a successful rebuild, ensuring a perfect fit and reliable, long-lasting performance on the water.

Key Kit Components & Their Functions:

• T-Seal Kit (Center Section Seals): This crucial set of inner and outer T-seals creates the primary barrier against water intrusion along the main motor shaft, located in the center housing.
• O-Rings: Provides a watertight seal between the lower unit housing and the end bells, a common point for leaks if compromised.
• Brush & Spring Assembly: A complete set of new motor brushes and springs. Worn brushes are a primary cause of power loss, excessive noise, and poor efficiency. Replacing them restores the motor's electrical connection for maximum torque and RPM.
   
   
• Brush Plate Assembly: The foundation that holds the brushes in their correct alignment, ensuring proper contact with the armature's commutator.
   
• Ball Bearing: A high-quality replacement ball bearing provides smooth, friction-free rotation for the armature, reducing noise and improving efficiency.
• Prop Shaft Seals: Includes the outer seal and the inner seal with a protective seal cup. This is the first line of defense against water entering the motor housing via the propeller shaft.
• Steel & Rubber Washers: Essential for proper spacing and tension within the motor assembly.

Important Note on Fitment: The most reliable way to confirm this kit is right for your motor is to measure the outside diameter of the lower unit (the "can" or motor housing). If it measures 3-5/8 inches, this kit is designed to fit. It is not compatible with larger 4" or smaller 3-1/4" diameter motors. Please verify your motor size before ordering to ensure a successful rebuild.
