Installation Guide

  1. Safety First: Ensure the outboard engine is turned off and the shifter is in the neutral position. Disconnect the battery for added safety.
  2. Access the Shift Rod: Remove the engine cowl to gain access to the shift mechanism and the old boot protector.
  3. Remove the Old Boot: Carefully pry or pull the old, deteriorated boot off the shift rod cap. Clean any residue or debris from the mounting area.
  4. Install the New Boot: Align the new boot protector over the shift rod cap.
  5. Press to Secure: Apply firm and even pressure to press the boot down until it snaps or seats securely into place, creating a tight seal.
  6. Final Check: Test the shift lever to ensure it moves smoothly through all gears without any binding or obstruction from the new boot. Reinstall the engine cowl.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
