Part Number: BRUSHKIT3.62

Minn Kota Brush and Seal Kit for 3-5/8" Diameter Lower Units 1991 - Present

Fits all Minn Kota Trolling Motors that have a lower unit with an outside diameter of 3-5/8" with the exception of 70 pound thrust models built after 2018 or that have been upgraded to the Core 128 Armature Assembly.  If your 70# thrust lower unit has a Core 128 Armature Assembly, you will need the BRUSHKIT3.62(70).

Typical thrust levels include 46-70 pounds.

Not sure if this kit will fit your trolling motor?  Measure the outside diameter of the Plain End Housing and if it measures 3-5/8", this kit will fit your trolling motor.

Anytime a lower unit is reassembled, the thru bolts need to be tightened within 35 - 45 inch pounds for 3-5/8" diameter lower units.

The Rebuild

I've dealt with Northland Marine several times in the last five years. Each and every time, Andrew Boers has been the "go to guy" at Northland. His knowledge of Minn Kota parts and their application to specific trolling motors is truly amazing. He's a walking Minn Kota encyclopedia!! Moreover, he not only knows the motors and parts, he is absolutely amazing at helping you disassemble and reassemble the motors! I won't use any other marine dealer for Minn Kota parts. They're simply that good.

easy install, fast shipping

The kit is easy to install and of high quality. Took about 1 hour after I cleaned my armature. I also installed a new magnet case for a magnet was cracked. Now runs very smooth. Fast shipping to Pennsylvania. Very impressed!

Endura 55 rebuild

Parts all fit perfectly and motor works great.
