- Next, remove the two bolts on both sides of the nut. These are long bolts, remember that it may take some doing if you are doing it manually.
- Once both bolts and the nut have been removed, the armature can be pulled out easily.

To diagnose and repair this Minn Kota Trolling Motor;
- Remove the top cover first. You will find six long screws holding the circuit cover. Remove them with the help of a Phillips head screwdriver and gently pull the top cover off. If you are unable to, note that some older models used to have eight screws as well.
- Once the head is removed, you will find all the circuitry therein.
- If, after diagnosing, you conclude that the problem is with the motor, take a closer look and as mentioned above, mark the orientation.
- You will need to pull out a pin that holds the propeller blades with the shaft. It can be found in a slot within the propeller.
- Remove the top nut and file down the shaft with a 220-grit sandpaper. About half a minute of scuffing should be enough.
- Pull out the top cover with your hand or with the pry bar.

3. Minn Kota Riptide Trolling Motor
This is a 70-pound thrust trolling motor. One of the most common problems with this trolling motor is that a part within may break if you hit debris or rocks, which may require you to open it up and repair it.
You can disassemble the Minn Kota Riptide Trolling Motor easily by following these steps;
- You will need a ½” hex socket wrench to take off the end-cap of your propeller. This step will require some effort, so just hold on to the propeller head and twist until the small disc comes off. Be careful; the headpiece is made out of zinc and may break due to corrosion.
- It should expose the shaft a bit. Pull out the end-cap, and the shaft will then be exposed. Be careful when removing the cap; there’s a washer in there that may fall off.
- You will find two bolts at both ends of the next cap. You will need a 5/16” hex socket wrench for this. Remember, these bolts go all the way through the assembly, so be patient when pulling these out. There’s a rubber washer on these bolts to keep the water out.
- The next piece will come off automatically. A rubber seal will be holding it together so you will have to tug on it a bit. You will then see the magnet and coils.
- You can pull the magnet out of the lower end-cap quite easily. It’s a bit heavy so be careful.
- Simply lift it, and you will expose all the circuits. There is another, bigger seal here.
- Use a T20 screwdriver to pull out the parts further. . There will be two screws here that you need to remove.
- You will then be able to pull out the whole circuit. Just remember that it will be attached at the bottom with at least two wires.

4. Minn Kota Edge 55
The Minn Kota Edge 55 is a 45-55 pound thrust trolling motor that often comes with a foot pedal.
This troll motor disassembly and assembly is fairly easy, but there is one complication to keep in mind; if anything inside breaks, it will most likely break other things too, and you will therefore need to be careful of that.
You can easily find the parts for this motor on eBay, Amazon, Minn Kota website, or any local parts shop due to the extensive use this motor finds. To take this motor apart, follow these instructions.
- There are three screws on the shaft to pull out the head.
- Remove the four bolts that hold the headcap in place (next to the handle). You can pull off the headcap after that to expose the wiring within. This is your control mechanism.
- The Minn Kota Edge 55 has a 45” (3.75 feet) shaft that may not fit many boats. Just like the three screws on the top, there are three screws at the bottom that you can unscrew to pull out the shaft and replace it with a shorter (or longer) one.
- If you are looking to repair the head (because of a broken head or a stiff throttle), you will find three screws holding everything in place with the help of a metallic plate. Unscrew those, and you’ll get better access to the wires.
- There are two more plates that you can remove to remove and clean out the gears as well.
- To repair the Minn Kota trolling motor’s bottom, refer to the same guidelines presented for Minn Kota Rip Tide’s lower unit.

5. Minn Kota SP70
This 70-pound thrust trolling motor is, in every sense of the word, a monster. It’s big and very useful when looking to catch some big fish, or simply when going out on rougher waters. However, one problem that you might face – especially in colder regions – is that saltwater may make its way into the turning head.
Normally, this wouldn’t present a problem but if you live in a cold area, you will end up with freezing saltwater within the turning head, and need replacement.
- Start by ordering a replacement part – otherwise, your trolling motor will be useless until the summer – when everything melts. However, even then, you will find that the turning head will be stiff until a point where you won’t be able to turn it even in the summer.
- Now open the head of your Minn Kota SP70. There should be four Phillips screws along with a water seal holding them in place.
- If there is corrosion on the wires, put some grease on them when reassembling.
- There will be another longer screw at the base of its head. Unscrew it and simply wiggle the head off.
- After this, you should be able to remove the shaft by simply pulling it out from the bottom.
The lower unit can be opened up just like other Minn Kota trolling motors. Here is a video to help you visualize the process.
Taking apart a Minn Kota trolling motor is easier than it seems – and if you mark the orientation and remember how you pull it apart, repairing and reassembling them becomes even easier. All it requires is a level head and presence of mind. The tools required can be found at any hardware store while the replacement parts can be found at the Minn Kota store or Amazon.
