Propeller Information and Maintenance

Replacement Propellers

To determine which propeller you need, please see the owner's manual for your motor. You can access the manuals by clicking this link. We do not recommend using an aftermarket prop on your Minn Kota Motor as it will increase the amp draw of the motor causing it to overheat and will void the warranty. There is a PDF available for downloading and printing at the bottom of the page for replacing the propeller.  If you do not see the prop kit you're looking for listed, it is no longer available

Propeller Maintenance

It is recommended that you remove the propeller after every use to inspect for fishing line and weeds.

Propeller Vibration

Props and shafts are not 100% symmetrical. Often times simply removing the prop, rotating it 180 degrees, and re-installing it will lessen or eliminate the incidence of vibration. If this does not correct the problem then you should contact your local Minn Kota service provider for an evaluation.

Propeller Replacement

The steps below will walk you through replacing your propeller. There are also videos below the step by step instructions showing how to replace your propeller. 

NOTE: Only tighten the propeller nut / anode a 1/4 turn past snug [25-35 inch lbs.]. Over tightening can damage the propeller.

CAUTION:  Always wear safety glasses and gloves. Disconnect all power to the trolling motor before beginning any work or maintenance. Johnson Outdoors Inc is not responsible for any damage due to improper rigging or installation. If you do not have the skills, experience and tools to perform the following maintenance and repairs, we recommend you seek the help of a Minn Kota Authorized Service Center. Or contact our Technical Service Department by submitting a request to the Minn Kota Help Center.

Tools Required:

  • Wrench (either a 1/2" or 9/16" depending on the model)
  • Flat Blade Screwdriver (only needed if the prop pin is broken)
  1. Disconnect the positive motor lead from the battery prior to changing the propeller.
  2. Hold the propeller and loosen the prop nut with a pliers or a wrench.
  3. Remove prop nut and washer. If the drive pin is sheared/broken, you will need to hold the shaft steady with a screwdriver blade pressed into the slot on the end of the shaft (Figure 1).
  4. Turn the old prop to horizontal (Figure 2), to prevent the drive pin from falling out, and pull it straight off. If the drive pin does fall out, push it back into the armature shaft.
  5. Align new propeller with drive pin.
  6. Install prop washer and prop nut.
  7. Tighten prop nut 1/4 turn past snug, [25-35 inch lbs.].

CAUTION: Over tightening can damage prop and bend the drive pin.
DISCONNECT THE MOTOR FROM THE BATTERY BEFORE BEGINNING ANY PROP WORK OR MAINTENANCE.

NOTE:
We recommend removing the prop after every use to check for weeds or fishing line that may be caught behind it (Figure 3). This can result in damage to the seals and allow water into the motor (Figure 4). Debris is not always visible (Figure 2) which is why the prop must be remove to be properly inspected.

NOTE:  
If you experience prop vibration, oftentimes removing the prop, rotating it 180°, and re-installing the prop will lessen or eliminate the incidence of vibration as all props and shafts are not 100% symmetrical.
