Propeller Inspection and Maintenance
• Inspect the leading edge of the propeller frequently for nicks, gouges, and damage.
• Propellers with large, deep dents, gouges, or torn metal should be replaced or repaired.
• Mineral deposits on stainless steel propellers can be caused by an inoperative or missing MerCathode system.
NOTE: Mineral deposits can be removed with household cleaners such as vinegar or other cleaners that remove lime and
mineral deposits.
