Those small metal pieces on your running gear, called sacrificial anodes, are your boat’s unsung heroes. They protect your propellers, rudders, trim tabs, and more from corrosion. No matter if you’re in freshwater, saltwater, or both, they help keep your boat safe.
Anodes act like shields for your boat. They corrode first, which protects your more expensive parts. Make sure to choose the right type for the water you use.
- Saltwater: Zinc or aluminum
- Freshwater: Magnesium
- Both: Aluminum (best all-around option)
Replace your anodes every year or when they wear down to half their original size. If you notice unusual wear, it’s a good idea to look into it further. Checking your anodes now can help you avoid bigger problems and get your boating season off to a good start.
