Complete Pro-Series Rebuild Kit for Minn Kota 3-1/4" Trolling Motors
Bring your trusted Minn Kota trolling motor back to factory-spec performance and ensure years of future reliability with this comprehensive motor rebuild kit. Designed specifically for Minn Kota's ubiquitous 3-1/4" diameter lower units (motor housings), this kit contains all the essential, high-wear components needed to perform a complete and professional overhaul.
Over time, the internal components of even the most reliable trolling motors can wear down. Brushes lose material, seals can become brittle and fail, and bearings can develop play, all of which leads to reduced power, increased noise, and the potential for catastrophic water intrusion. This rebuild kit addresses all of these failure points in one convenient package, providing everything you need to restore the heart of your motor.
By rebuilding the motor, you can fix issues like slow or inconsistent speeds, grinding noises, and intermittent operation. It is the perfect solution for routine preventative maintenance on a motor with high hours or for bringing a non-functioning motor back to life, saving you the significant cost of a brand-new unit.
Compatibility:
This rebuild kit is designed exclusively for Minn Kota freshwater and saltwater trolling motors that utilize a 3-1/4" outside diameter lower unit housing. This is one of the most common motor sizes produced by Minn Kota over the years.
The kit is compatible with, but not limited to, the following Minn Kota motor models:
All Terrain (AT) Series:
- 30AT, 33AT, 36AT, 40AT, 42AT, 44AT
Edge Series:
- 40, 45
Endura & Endura C2 Series:
- 30, 34, 36, 38, 40, 42, 45
Endura Pro Series:
- 32, 38
PowerDrive & PowerDrive V2 Series:
- 36, 40, 42
Classic Series:
- 28, 36, 40
Other Models:
- 35A, 35TA, 65, 65TA
- 365T, 365TA
- Spider 48
- Various other models with thrust ratings typically between 28 lbs and 45 lbs.
Important Note on Verification: The most reliable way to confirm compatibility is to measure the outside diameter of your motor's lower unit (the "can" at the bottom). If it measures 3-1/4 inches, this kit is designed for your motor. It is not compatible with larger motors (e.g., 3-5/8" or 4" diameters) found on higher-thrust models. Always verify your motor size before ordering to ensure a perfect fit and a successful rebuild.

A close fit
My model 35 doesn’t quite follow Minnkota “standard” parts. But worth a try. Customer service is great at Mike’s! I am sourcing the bearing to make the kit fit my motor. I’m good with that.

Minkota 3.25" rebuild kit
Everything worked well. The average guy would probably like some instructions. I used rtv silicone as well as the O rings and the seals, as the housings were a little corroded, so even after cleanup they were a bit pitted. But the parts fit perfectly and it all worked out and works fine just like new.
