Zinc is the traditional choice for saltwater, aluminum works in both salt and brackish water and is a common modern choice, and magnesium is for freshwater only. Picking the wrong metal lets your expensive parts corrode instead, so match the anode to where you keep the boat.

Tecnoseal offers complete anode kits for Mercury Alpha, Yamaha, Volvo, and other drives with the right hardware included, plus plate and bar anodes for hulls and brackets. Inspect anodes through the season and replace them once they are about half consumed to keep protection steady.
Zinc suits saltwater, aluminum works in salt and brackish water, and magnesium is for freshwater only. Match the metal to where you keep the boat so the anode protects your parts.
Replace an anode once it is about half consumed. A heavily wasted anode no longer protects your engine and drive, leaving the metal at risk.
Many Tecnoseal anode kits for Mercury, Yamaha, and Volvo drives include the mounting hardware needed for that engine. Check the listing to confirm what is included.
