  1. Great rebuild kit for Minn Kota 55 lb motor 5 Star Review

    Posted by on Sep 24th 2025

    These rebuild kits are surprisingly difficult to find. Of the few places I found that had them in stock, Trolling Motor Parts had the best price. The kit had everything I needed to rebuild my motors.

  2. Perfect Rebuild for Terrova Lower Unit 5 Star Review

    Posted by on Sep 16th 2025

    I was having issues with my 2011 Terrova draining the battery and periodically stalling during operation. After disassembling the lower unit and finding water in the unit I searched for a rebuild kit and found this one available on TrollingMotorParts.com. Following a YouTube video that I found elsewhere, I was able to disassemble and reassemble the unit rather quickly and with little difficulty. At this point, the motor runs smoothly and seems to be operationally fine (although I have not water tested it at this point.)

  5. Little Known Fact 5 Star Review

    Posted by on May 7th 2025

    Something none of the several YouTube videos I watched mentioned: the kit includes a "paper tube". What the heck is that for you say? Apparently it can be used to hold back the brushes {thus the description "brush retention") while the replacement armature is inserted. Not absolutely required since apparently most people just use their fingers to separate the brushes, but potentially useful nonetheless.

  8. easy way to renew a trolling motor 5 Star Review

    Posted by on Sep 14th 2024

    My trolling motor is 20 years old it started to slow down. I thought maybe it started leaking water inside due to age. I was wrong about that however I rebuilt it with parts from here and was super simple to do now my trolling motor is like it’s new. I’m very happy the results.
