    The parts that I received came in an acceptable time and were a perfect fit. After I reassembled the troll motor I put it in the water, and It worked like a new toy. I’d definitely recommend (trollingmotorparts.com) for all the parts for your tolling services and needs.

  5. Perfect for Minn Kota 55 lb thrust rebuild 5 Star Review

    Posted by on Oct 2nd 2025

    This kit included all of the parts I needed to rebuild my Minn Kota 55 lb thrust trolling motor. I didn't realize the seals on these motors give out frequently and should be replaced every couple of years. I'm sure I will be ordering this again.

  6. 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.

  7. 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.)

  9. Acciurate and quality 5 Star Review

    Posted by on Jun 9th 2025

    Easy to find what I needed, received parts in good manner, quality parts……Recommend this company highly..

  10. 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.
