Before repairing a propeller, make sure the hub is in good shape. You would replace the hub first if it were defective. Because this operation necessitates a large deal of pressure, caution should be exercised to avoid harm. Several lubricants are effective. Any lubricant used must be water-soluble and include no petroleum additives. The petroleum additives will cause the rubber to degrade and fail. To make installation easier, soak new hubs for a few minutes in hot water (about 180 degrees Fahrenheit). It will cause no damage to the hub and allow it to compress with less force.
