When will I know it's time to change the sacrificial anodes of my PWC?
Sacrificial anodes are specifically designed to protect parts of your personal watercraft that are underwater from galvanic corrosion. Like its name implies, they essentially ''sacrifice'' themselves by absorbing the electrochemical process of corrosion to prevent metal components like the impeller, jet pump nozzle or engine from being ''eaten away'' instead. Galvanic corrosion can cause major damage to your PWC if not controlled. Inspect your sacrificial anode at least once a month. Replace your anodes when they are 50% depleted.
