Complete Rebuild Kit for Classic Minn Kota 4" Trolling Motors

Bring new life and restore the original factory performance to your trusted older Minn Kota trolling motor with this comprehensive 4" Motor Rebuild Kit. Designed specifically for classic models with a 4-inch diameter lower unit housing, this kit contains all the essential, high-wear internal components needed to perform a complete and thorough overhaul.

Over years of hard use, components like brushes, seals, and bearings wear down, leading to decreased power, increased noise, and potential water intrusion. Instead of replacing your entire motor, this all-in-one kit allows you to replace the core electrical and mechanical parts, ensuring many more years of reliable service on the water. It’s the perfect solution for the DIY-minded angler looking to maintain their legendary Minn Kota motor.

This kit addresses the most common failure points in an older trolling motor, restoring lost power and efficiency. By replacing these critical parts, you can expect quieter operation, a noticeable increase in thrust, and better battery life.

Compatibility:

This rebuild kit is designed exclusively for older Minn Kota trolling motor models that feature a 4-inch outside diameter lower unit housing. It is crucial to measure your motor housing before ordering to ensure a proper fit.

This kit is compatible with a wide range of legacy Minn Kota motors, including many of the most popular models produced through the 1990s and 2000s.

Common Compatible Models Include (but are not limited to):

• All Terrain (AT) Series:

  • 48AT, 55AT, 65AT, 70AT

• Maxxum Series (4" Housings Only):

  • 55, 65, 70 (including both transom and bow-mount versions)

• Endura Series (4" Housings Only):

  • Many models in the 46, 50, and 55 lb. thrust range.

• PowerDrive Series (4" Housings Only):

  • Models in the 65 and 70 lb. thrust range (e.g., PD65, PD70).

• AutoPilot Series (4" Housings Only):

  • Models based on the PowerDrive platform with 65 and 70 lb. thrust ratings.

• Classic Magnum & Spider Series:

  • 48M, 48S, 65M, 65S

Important Fitment Notes:

• Voltage: This kit is typically designed for motors across various voltages (12v, 24v, and 36v) as the internal components are often shared. However, always confirm the voltage compatibility if specified by the kit supplier.
• Thrust Rating: This kit fits a wide range of thrust ratings, generally from 46 lbs up to 70 lbs, as long as the motor has a 4" diameter housing.
• Exclusions: This kit will NOT fit smaller motors with 3-1/4" or 3-5/8" housings (like the Endura 30). It will also NOT fit newer motor designs or those with larger "Variable" or "Digital" motor housings, even if the thrust rating is similar.

If you own a classic, powerful Minn Kota motor that has lost a step, this 4" Motor Rebuild Kit is the most cost-effective and reliable way to restore its power and ensure it remains your trusted partner on the water.
