Installing a Prop

Correctly installing a propeller is essential for optimal performance for your trolling motor and ensures optimal performance and safety. This guide will walk you through the essential steps, tools, and tips needed to successfully install a propeller, making the process straightforward and stress-free.

Prop Installation Video

Tools Needed:

  • Wrench (either a ½” or 9/16” depending on the model)
  • Flat Blade Screwdriver (only needed if the prop pin is broken)

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 are unsure how or unable to perform the following, we recommend you seek the help of an Authorize Service Center or Click here to contact Minn Kota Technical Support.

  1. Disconnect the positive (+) motor lead from the battery prior to changing the propeller.
  2. Hold the propeller and loosen the prop nut with 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
  4. Turn the old prop to horizontal, 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.

NOTE: We recommend removing the prop after every use to check for weeds or fishing line that may be caught behind it. This can result in damage to the seals and allow water into the motor. Debris is not always visible, and prop must be remove to be properly inspected.
CAUTION: DISCONNECT THE MOTOR FROM THE BATTERY BEFORE BEGINNING ANY PROP WORK OR MAINTENANCE.

Prop Drive Pins

Replacing the Prop Pin

  1. Remove the propeller by removing the nut and washer holding the prop in place.
  2. The prop pin is located on the propeller shaft and is covered by the propeller.
  3. The pin should slide out. If it does not, you will need to tap it out with a punch.
  4. Slide the new pin in place.
  5. Slide the prop on and seat it over the prop pin.
  6. Replace the nut and washer for the propeller securely.
