Minn Kota trolling motor shaft replacement

How to replace a Minn Kota trolling motor shaft using a brush and armature kit.
Last time I was on the lake, I crashed my old trolling motor into some rocks and bent it. In this KZbin, I'll show you how I repair the bent trolling motor shaft using a brush and armature kit.

I'd never even touched a Trolling Motor until last weekend. Went out on my jon boat, bottomed my motor into the mud and it quit working about 20 minutes into my float...thought I was screwed. Then I came to YT, typed in "minn kota trolling motor", your video was 1st or 2nd I watched. Last night I took it apart, cleaned out a bunch of mud and sludge. Cleaned it up. Regreased everything. Put it together and viola! Thanks for your comprehensive video!

[@ProWrenching]

That's awesome! Glad my video was helpful. Thank you.

[@garypinholster2569]

Lot of help. My tips would be to tie the brushes back with zip ties around brush wire. One around skeg one around shaft. After armature is installed put something hollow over shaft, pvc pipe a couple of feet long, this allows you to hold pressure against armature when you slide the cover over it otherwise magnets will pull armature out.

[@jasonkrohn5416]

Thank you for the video, you probably saved my life, I was trying to figure out how to tell the wife I needed a new trolling motor. 😂

[@mick9850]

Too easy, I'm back on the water. Thanks legend

[@patrickweis4593]

I have the kit for the Maxxum sitting in my kitchen and have watched 4-5 videos and this one has been the best by far. Going to tackle it tonight - feel so much better about the job after seeing this. Great job!

[@ProWrenching]

Awesome! Thanks for the feedback. Glad the video was helpful.

[@patrickweis4593]

@@ProWrenching so far so good - but I am going in reverse! I reinstalled the brush plate (switching the polarity) and the prop is still spinning in the wrong direction....any ideas?

[@ProWrenching]

@@patrickweis4593 check to see if the motor case (main tube the motor goes in) is installed in the wrong direction. That could be it.

[@ProWrenching]

There’s only a slight difference in the ends of the tube and its easy to mistakenly install backwards.

[@patrickweis4593]

@@ProWrenching will do.... it looks like on the casing, each end has a beveled edge, one is about 1/2 to 3/4" deeper than the other. I looked at your video and it seems like the shallower edge goes toward the nose (brush end). Sound right?

[@marcduplessis553]

Great vidéo! Thanks for sharing your expertise.

Very helpful thank you!!!!!!!

[@ProWrenching]

Thanks!

[@pox489]

Thanks for sharing. I’ll have to change the bearing and seals on mine, would you recommend to grease the bearing, shaft, brushes and rotor? In that case, what grease woul you recommend?

[@ProWrenching]

Yes- I used dielectric silicone grease on the seal and shaft, but not the brushes or rotor. Thanks for watching!

[@arkadysokolov4701]

Which Torque is recommended for tightening axial screws, propeller nuts, for motors 3 1/4, 4 1/4 ? Thanks

[@marcduplessis553]

Hi! I ordered a new kit to replace the propeller shaft but mine didn’t come with a new brush plate assembly. Do I really need to replace the brush plate like you did in your vidéo. Thanks again!

[@ProWrenching]

If your brushes are still good, I’d say no need to change them.

[@dikki1990]

Do you happen to know what # that prop is I can't seem to find the right one

[@ProWrenching]

It’s a Weedless Wedge 2

[@noahbelcher5182]

How’d you find a kit, or did you just buy all the parts individually off of minn kota’s parts portal?

[@noahbelcher5182]

Thank you

[@user-tz4wy2zq9u]

anyone have the part # for the kit to rebuild endura c2 55lb lower unit?

[@fishbustin7926]

Can I use regular marine grease for that?

[@ProWrenching]

FishBustin- yes- marine grease would work fine for lubricating the seal. Thanks for watching!

[@pistonforge]

where i can order the motor shaft like the kit you got? on minn kota they only sell the entire motor unit already sealed but my casing is intact only the shaft is bend a litle bit..enought to shake pass speed 5-6.. ty sir

[@ProWrenching]

I see the armature for sale on the Minn Kota parts website: motors.Johnsonoutdoors.com. Have you checked that site out?

[@richward2288]

Is yours the 55 lb. thrust? What was the part number for the armature? For my 2015 Edge 55 lb. Minn Kota says the number changed.

[@ProWrenching]

Mine is the 70 lb thrust so it probably is a different part number. I don’t have that number, but I found it on the Minn Kota website.

[@richward2288]

@@ProWrenching thanks, I got the number from Minn Kota site, just wanted to compare. Great video, I'm happy to not have to plow that ground for the first time.,😀

[@ProWrenching]

@@richward2288 thanks. Working on another repair video as we speak- changing out the base plate on my trolling motor due to it being worn out. Gotta keep these trolling motors running!

[@avidwaterfowler7522]

There has to be someone that can straighten these shafts? I beat the shit out of my trolling motors since I use them for duck hunting.

[@kendallkilgore7799]

Is that all one kit? Fishing line got in mine and pulled the shaft seal out and water nuked everything inside the lower unit.

[@ProWrenching]

I bought a kit from minnkota.johnsonoutdoors.com. You can look up parts on their website using the serial number of your trolling motor

[@kendallkilgore7799]

@Pro Wrenching I am going for a full lower unit but am having issues as to how the lower unit attaches to the shsft.

[@ProWrenching]

@@kendallkilgore7799 I suggest calling the Minnkota technical support line at 1-800-227-6433. I have called them before and they have been a great help.

[@stevebasanyi4374]

Looks great, but i have this cardboard ring, (brush retainer)? Not sure where it goes under the brushes?

[@ProWrenching]

You might try the MinnKota Johnson Outdoors website. If you look up your motor by serial number on that website, you can find some excellent parts diagrams that may answer your question.

[@stevebasanyi4374]

I've looked at parts diagrams, and it says "brush retainer". It costs about 50 cents, lol. Mine was flopping all around in the bottom of the brush plate. I dont understand the point of it. No one has explained what it does. Any info?

[@ProWrenching]

@@stevebasanyi4374 I don’t recall seeing that with my motor. We can leave your comment here and maybe some other viewers will respond with the answer!

[@AlissonHora76]

Hello, friend! Do you would send to Brazil the kit for Endura 34lbs

[@ProWrenching]

Hello! Sorry- I don’t sell them.

[@fisherlism8774]

I can't take out ARMATURE. I think bearing has rust with BRUSH PLATE W/HOLDER. Do you have any idea?

[@ProWrenching]

You might try some penetrating oil and let it soak.

[@fisherlism8774]

@@ProWrenching I try to use sonax soak 2days still not out. I will try more. Thank you for your help.

[@ahordos17]

I have a very small bit of play in my shaft. Is this normal?

[@ProWrenching]

As long as it’s not enough play to damage the seal on the front of the motor that keeps out the water, it should be OK.

[@billspradlin9619]

I have a Minn Kota trolling motor Endura C2 30lb thrust. Does anybody know what that molded / epoxied section in the front motor case is? It has there wires into it, two-yellow and one white. Sure it's part of the speed controller. Maybe the Power MOSFET drivers. Placing in the motor case in the water to keep them cooler (Of course just guessing). I'll take back what I mentioned about that incased/potted section in front of the motor compartment. I saw the part description of that part, SPCOIL Speed Coils - FW potted. I ohmed those three wires "YEL/WHT/YEL" all three of them ohm out to zero ohms. So maybe those are coils / inductors / surge protectors ????

[@ProWrenching]

Maybe a viewer with this trolling motor will be able to answer. The Minn Kota website has parts diagrams that might be helpful and they also have a tech helpline. 1-800-227-6433 Mon-Fri

I woulda ran it another 2 years like that lol

[@ProWrenching]

The way the economy is looking now, I’m gonna have to start running everything longer!

[@nuwanr7179]

Sir..i want made this in my home..but i havent buy this motor in my country..can you sujest sutable motor this for use..vehicle radiator fan motor or etc...sorry my english is bad.im from sri lanka

[@ProWrenching]

Thank you for watching over there in Sri Lanka! I don’t know of any motor you could use in place of a trolling motor under the water. Trolling motors are sealed so they can be used under water. A radiator fan motor, etc, wouldn’t be sealed and the water would ruin it. If you were going to use a different motor that wasn’t waterproof, you would have to keep that up out of the water and have an extended shaft running to the propeller in the water. I bet you could use a radiator motor if it was out of the water with an extension shaft to the blade. I’ve never tried it!
