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.
