Installation and Maintenance

Replacing the propeller nut is a task that should not be taken lightly. Regular inspection of the nut's condition prevents unexpected failures during your trip. Remember to use the tightening torques recommended by the manufacturer during installation. A loose fit can cause the propeller to slip, while overtightening may damage the drive shaft threads. By using the original Parsun part, you can be confident that the corrosion-resistant and vibration-dampening material will ensure a long lifespan for your propulsion system.
